If the WMAP data is combined with other cosmological data, the best estimate is 70.4 1.4 (km/sec)/Mpc. This experiment modeled the expansion of the universe. An image of the CMB by the balloon-borne BOOMERANG that journeyed through the stratosphere above Antarctica in late 1998. You will need the following items: A round balloon (do not use a long, thin one).
You might find it easier in the next step if you put all 5 on the same hemisphere. expanding universe balloon experiment 29.4M views Discover short videos related to expanding universe balloon experiment on TikTok. The circles represent galaxies. Ever since, the universe has been expanding. I assume that the constant readings are not constant but increasing in decimal numbers. experiment is proposed as a metaphor for describing one of the most intriguing facts of cosmological theories, i.e. Another method, used by scientists working with the Hubble Space Telescope, for example, involves looking at "Cepheid Variables" in distant galaxies. If the balloon is in a colder environment, then it will shrink or contract. It posed some questions at the end - and if you've come here, you probably want to know more. The second law defines the force on an object as the . Save.
Distance between stars are measured after each pump was accomplished. 2. S universe = S water + S air Title: Newton's Balloons. Some coloured stick-on dots (at least 5 different colours). You may want to look at both of them and de-cide which sequence is best for your students. The results of this study have been submitted to the journal Nature. Consider using the analogy of a loaf of raisin bread expanding as it bakes, with the dough representing space-time and the raisins representing galaxies or galaxy clusters. In the 1920's, astronomer Edwin Hubble observed that the galaxies are moving in the same way. Experiment To Prove Expanding Nature Of Universe. This activity is part of the "Cosmic Questions" educator's guide that was developed to support the Cosmic Questions exhibit. The "big bang" theory places the origin between 10 and 20 billion years ago, when the universe began in a hot dense state; according to this theory, the universe has been expanding ever since. Step 4 - Place two teaspoons of baking soda into the funnel so it falls into the balloon. The balloon represents the universe. 2. 1. . -The balloon represents the universe and the dots are the galaxies. the Hubble law of space-time expansion. Ball on a Spring (Quantum) 3. The readings of distance between stars created during the expansion of the balloon are then recorded. Next, attach the balloon to the top of the flask; make sure not to pour the baking soda into the. Explain to students that the balloon represents space-time, and the dots represent galaxies or galaxy clusters. . Terms and Concepts Mylar Matter States (of matter) Solid Liquid Gas Plasma However, a recent discovery involving . The expansion rate at the present time, H o, is about 70 km/s/Mpc (where 1 Mpc = 10 6 parsec = 3.26 10 6 light-y). The discovery was apparently made while experts were working on an experiment in Antarctica to detect cosmic rays. Recent observations by astonomers about large-scale geometry of universe and total amount of matter and energy it contains support Dr Alan Guth's 1980 theory about what set off Big Bang explosion . (Note: If this exercise is available and being conducted online, the setup, materials, and directions may differ. I've heard that the universe is expanding similar to a balloon being blown up with all reference points growing further apart. Saul Perlmutter, who led one of two teams that simultaneously discovered the accelerating expansion of the universe, has been awarded the 2011 Nobel Prize in Physics, to be shared with two members of the rival team. So here are ten top questions about the expanding Universe, answered for us by Dr Francisco . If this is true, then all movement is perpendicular to the point of origin (the "center of the balloon"). Figure 5: Dark energy experiment balloons Tell students Fact 2: Gravity of dark matter and normal matter holds everything in Universe together. 1. As you do this, look at the movement of the three dots. The Expanding Universe: A Model Introduction In this activity you will use a balloon to model the expansion of the universe. Resonance; 2. The following are the readings of . Give one weakness of this balloon model in representing the idea of an expanding Universe. If you would like to save time, have a strip of elastic and 5 sequins or buttons sewed on (for each group) prepared in advance. So we have a balloon for a model. Balloon Blow-Up Experiment Directions: Have your children scoop the baking soda into the balloon using the funnel. The independent variable in my experiment is . The distance from each dot to the Home dot increased every time the balloon expanded. Visit. Ball on a Spring (Classical) 1a. Yet it took the microwaves of that afterglow originating from its outskirts 13.7 billion years to reach us. Explore 1. if you imagine yourself living on the surface of the balloon, you can run experiments by drawing triangles and summing their angles. . The experimental points show the results of the early experiments in 1990. 5) Measure the distances to each of the dots and the balloon's circumference. With the universe at a "small" size, measure the distance from galaxy #1 to galaxies 2, 3, 4 . Dark energy is though to make up between 67-70% of the universe. You have a balloon in a vacuum. The XL-Calibur project is currently funded by a $4 million NASA grant and international contributions. The first results from a balloon-borne experiment peering back to a time shortly after the big bang provide confirmation of a mysterious "dark matter" and "dark energy" that make up most of the .

In this experiment, the system is the water, the surroundings are the air in the room. An easy way to visualize the expanding universe is to drop a spatial dimension and pretend that the observed universe is 2-dimensional. One way is to increase the pressure, but that's like creating energy ex nihilo. Use the markers to make 10-15 dots on the balloon and number 10 of them after the balloon is partially inflated. Consider using the analogy of a loaf of raisin bread expanding as it bakes, with the dough representing space-time and the raisins representing galaxies or galaxy clusters. Independent Variable. _____ 3. Each of the dots represents a whole galaxy, with the surface of the balloon being the Universe that they exist in. 3. with 4 medium breaths to about the size of your fist; do not over inflate the balloon! Materials balloon 25cm of string Procedure science-mattersblog.blogspot.com. The problem is that the entire Universe has been and still is expanding at an incredible rate. As the balloon was inflated, the dots moved farther away from the home dot and each other. The balloon represents the universe. sentences. Based on the models, is the Universe expanding, contracting, or staying the same? Use a marker to make small, filled in circles on the balloon. The elastic represents space; the sequins /buttons represent galaxies. What we would call the inside and outside of the balloon is NOT part of the model, just the 2-d rubber part. Long a staple of science fiction, it's possible that scientific observations here on Earth could provide evidence for the existence of parallel Universes. there is a limit to how far the balloon can expand. Despite this effect of gravity, Universe has been expanding and galaxies fly away from each other. The shortcomings of the experimental design is what the universe has no known limit to which it can grow, as for a balloon . It was the first experiment to make large, high-fidelity images of the CMB temperature . See the As the balloon expands, the distance between the dots or "galaxies" become farther apart. 6. You can draw more galaxies, if they are decorative. He or she will give you and your partner a balloon and a permanent marker. Results; Conclusion; Gallery; Bibliography; Question How does temperature affect gases behavior? The experiment was done by accomplishing ten pumps. 4 . Students should work in groups of 3. The findings also clear up the sources of the Far Infrared Background, long shrouded in mystery. You may wish to make some of the points . The universe is expanding as the cosmologists say and the analogy given as in the expanding balloon. The pressure inside is balanced by the tension in the skin, and there's two ways to make it bigger. The circles represent the galaxies. The results demonstrate that various parts of a Wubble Bubble Ball undergo approximately uniform expansion; moreover, with the increase of the balloon diameter, the slope of the fit line decreases gradually, i.e. Long a staple of science fiction, it's possible that scientific observations here on Earth could provide evidence for the existence of parallel Universes. The MAXIMA team launched its balloon twice from the National Scientific Ballooning facility in Palestine, Texas. At each Stage you will measure the distance between the dots. What do current LHC results (mid-August 2011) imply about supersymmetry? The universe as we know it began with an event known as the big bang. But gravitational redshift is rarely significant; two other effects are far . Place the thermometer and all three balloonsone at a time, if necessaryin the area where you have chosen to do your cold-temperature testing; such as in the freezer. Explain to students that the balloon represents space-time, and the dots represent galaxies or galaxy clusters. This activity can be in conjunction with, or independently . theory supported by results from other experiments. Stick your five dots onto the balloon. The Painted Balloon Experiment The observation of cloud segmentation dynamics is the definitive measurement for the gravitational expansion of mass, space and time. Procedures: 1. Their new experiment, already making observations, uses 2,560 detectors. The new measurements were accepted as important evidence for a hot early Universe (big . it's possible that the universe is still expanding as the researchers describe it more like an inflating balloon. The balloon obviously is expanding into the surrounding space, so it is easy to see why many people might think there must be something outside of the universe for the universe to expand into. A piece of string . This activity is part of the "Cosmic Questions" educator's guide that was developed to support the Cosmic Questions exhibit. It represents how change plays a big part in the theory because it's a never ending expansion therefore never being the same. Blow up the balloon a little bit and hold the "nozzle" closed, but do not tie it up. This relationship means that the further a galaxy is from Earth . Sewing is involved. Step 5 - Next, secure the mouth of the balloon over the mouth of the bottle. Results announced last year from MAXIMA and BOOMERANG, another balloon-borne experiment, showed that the Universe is flat. Now choose 6-12 circle . If clouds didn't segment the way they do, then it would be a decisive proof of either General Relativity's curved gravitational spacetime or Newton's flat gravitational . then the big bang model . Moreover no raisin, or galaxy, occupies a special place in this universe - unless you get too close to the edge of the loaf where the analogy breaks down. Draw 5 "galaxies" randomly on the balloon and number them. Recent measurements (c. 2001) by a number of ground-based and balloon-based experiments, including MAT/TOCO, Boomerang, Maxima, and DASI, have shown that the brightest spots are about 1 degree across. Tell students that in fact Universe expansion has become faster. When Hubble observed the redshift of the light coming from stars and galaxies , he realized that the galaxies were moving away from each other . Use a marker to make small, filled-in circles on the balloon. Dark energy is how scientists refer to the force that is thought to be behind the expansion of the universe. This distance between different points is because of the expansion process. Try to spread them out over the whole balloon. Record below what happens to the dots. the system. Hubble concluded that the universe is expanding, just like our balloon expanded. If your results show that the sum of the angles is always greater than . On a flat, not-yet-inflated balloon, mark a series of points using a permanent marker. Balloon Galaxy Model Observations Center of the Universe Balloon Model Raisin Bread Galaxy Model Observations Raisin Bread Universe 1. : The origin of the universe remains one of the greatest questions in science.
The discovery of cosmic microwave background radiation constitutes a major development in modern physical cosmology.In 1964, US physicist Arno Allan Penzias and radio-astronomer Robert Woodrow Wilson discovered the CMB, estimating its temperature as 3.5 K, as they experimented with the Holmdel Horn Antenna. Use the permanent marker to make four to six small dots on one side of the balloon. The January 2008 Popular Astronomy carried a project in which you mark a balloon with galaxies, then blow up the balloon so that the galaxies expand away from each other, just as in the expanding Universe. Microwave Background Radiation and an Expanding Universe Name: Section: Course: Date: Your instructor has provided you with a balloon to represent the Universe. as the balloon expands the dots get further apart, representing the galaxies moving apart . expanding universe school observatory . These and future experiments not only help confirm that the universe inflated dramatically, but are providing theorists with the first clues about the exotic forces that drove space and time apart. Materials needed include a balloon, ruler, paper strip, a copy of this page, and a marker. Testing Your Balloons in the Cold Area. . The Expanding Universe: Balloon Model. Hypothesis (an educated prediction of what is going to happen and why) If a balloon can be a model of the expanding universe, then the locations marked on the balloon will _____ as the balloon is inflated, because _____ This is beacause gases contract in colder environment and they expand in warmeer environments. Alternatively, draw several dots on a balloon with a felt pen. Alternatively, draw several dots on a balloon with a felt pen. In this chemistry science fair project, you'll investigate these changes in average kinetic energy by using a different kind of balloona latex balloon, which is able to expand and contract as the force and frequency of the elastic collisions change with temperature. The common analogy of an expanding balloon illustrating the expansion of the universe probably helps fuel this misconception. Hubble's constant is approximately \ (2.3\times 10^ {-18}s^ {-1}\) if the distance is in metres and the speed in metres per second. An excellent closing activity may be to ask them how their experiments relate to our spatially 3-dimensional Universe. The surface of the balloon will represent space. Now begin to blow up the balloon. 3. They are . Before students begin the lab, you should let students know that, ultimately, they are about to examine what happens in a 1-dimensional Universe as it expands. 5. to the notion of the expanding universe and the Big Bang. The discoveries hail from the Balloon-borne Large Aperture Submillimetre Telescope (BLAST), which . Perlmutter, 52, a professor of physics at the University of California, Berkeley, and a faculty senior scientist at Lawrence . Take a deflated balloon and draw three dots on it, and label them 1, 2, and 3. experiment, you'll create a simple model to learn how the universe expands over time. This is what we call redshift, where something happens to make the wavelength of your light longer and lower in energy. Let's go back in time to the start of the universe and recreate the expansion! A new map of the early Universe has reinforced a long-running conundrum in astronomy over how fast the cosmos is expanding. Record the distances in the table as "Balloon Circumference # 1." Measure the balloon's circumference as well 4) Inflate the balloon so that its diameter is about 10 cm bigger ( 20 cm total). In sum, students will be using elastic with sewed-on sequins to model an expanding universe. 5.7 Data on the spectral distribution of the cosmic microwave radiation obtained from the COBE satellite experiment. If you can only put one balloon in at a time, this step will take 3 hours. the receding velocity of the labeled point relative to the reference point drops.
In this activity, students use rulers to measure distances between hypothetical galaxies and then use these distances to calculate the velocities of the galaxies.
The ACT is the first ground-based CMB experiment that could have challenged Planck's results, says Erminia Calabrese, a cosmologist at Cardiff University, UK, who led the analysis of the data. Pick four of the circles around the balloon and label these A, B, C, and D. Hypothesize what will happen to the distances between the labeled circles when you . Results released yesterday came from the radiation data captured by the first MAXIMA. You will place several dots on the balloon to represent galaxies and you will blow the balloon up in several Stages. Scientists led by Konstantinos Migkas at the University of Bonn in Germany analyzed data on x-rays released by hundreds of clusters of galaxies, revealing that the universe seems to be expanding. This is a simple, but fun lab to do about the expanding universe.
So the change in entropy of the universe, or S universe is a sum of the change in entropies of these individual components, assuming there is only energy exchange between water and air. . Waves (Classical Equation of . Reset image size Figure 5. Why so quiet at LHC? The theory of inflation predicts a period of rapid expansion of the early Universe and a "flat," or ordinary, geometry for the Universe, in addition to the fine scale variation in temperature. 1. ExpandinG Balloon UniversE Name: Lab partners: (credit: This lab was inspired by the University of Washington lab. Help your children put the vinegar into the flask using a pipette or small measuring cup. However, a recent discovery involving . Waves (Classical Form) 4. XL-Calibur reaches to higher X-ray energies, 15-80 kilo-electron volt per light particle (photon), compared to IXPE's 2-8 kilo-electron volt. You may want to consult or give out the background articles on galaxies and the universe from The Universe at Your Fingertips disk. When expressed as a function of cosmic time, H ( t ), it is known as the Hubble Parameter. The first law states that an object at rest tends to stay at rest and an object in motion tends to stay in motion, both unless the object is acted upon an outside force. The results show that the farther away a dot is from the home dot, the faster its movement. With a partner, pick a balloon. The data collected using a telescope in . The balloon is marked with a waveform repre- senting a light wave. The other way is to reduce the tension of the skin. Expanding Universe Experiment. The balloon represents the big bang theroy by showng constant expansion of the objects in space. to make 10 - 15 dots on the balloon and number 10 of them after the balloon is partially inflated. When the balloon is filled with the baking soda, carefully remove it from the funnel. Then think back to the balloon analogy for the expanding universe. This activity can be in conjunction with, or independently . Science. Equipment Needed Describe the motion of these galaxies (each raisin represents a galaxy in the bread model) relative to one another. 4. end of the balloon down and paper clip it so that no air escapes. Physicists have known the universe is expanding for years, but in the late 1990s, observations made it clear that the universe was not just growing larger but doing so at an accelerating rate. In this activity, students use rulers to measure distances between hypothetical galaxies and then use these distances to calculate the velocities of the galaxies. The current WMAP results show the Hubble Constant to be 71.0 2.5 (km/sec)/Mpc. If the universe were closed, the brightest spots would be greater than one degree across. Group members should decide on . Subjects. The balloon will represent the universe. Place an un-inflated balloon on the table. To understand how the redshift of galaxies is due to the expansion of the Universe, try the following experiment. But the balloon still has a center. Step 2 : Making the Measurements. The universe has 4 dimensions: height, width, depth, and time. Record these measurements as "Balloon Circumference # 2" in the table. The inverse of the Hubble Constant is the Hubble Time, tH = d / v = 1/H o; it reflects the time since a linear cosmic expansion has begun . Modeling the Expanding Universe Activity H9 Grade Level: 8-12 Credit: ACT Collaboration. Take a balloon and mark different points on balloons like galaxies are there in the universe. Your teacher will divide the class into pairs.
vinegar! When recent satellite data and those from balloon -borne experiments are combined, a very exact t
In this activity, you are going to create a model of the expanding Universe. The false-color image shows subtle fluctuations in the temperature of the hot plasma which filled the universe before expansion cooled the material, producing the familiar stars and galaxies. For decades, scientists have been conducting a series of Earth-based and space-based experiments to measure the rate of expansion of the Universe. Don't tie it off. Make a model for the expanding universe. 2. So, what was a miniscule distance of 380,000 light years back then turned into the enormous distance of 13.7 billion light years as of today . In astronomy and observational cosmology, the BOOMERanG experiment (Balloon Observations Of Millimetric Extragalactic Radiation ANd Geophysics) was an experiment which measured the cosmic microwave background radiation of a part of the sky during three sub-orbital (high-altitude) balloon flights. some believed the results could just have been down to a scientific glitch.

On a flat, not-yet-inflated balloon, mark a series of points using a permanent marker. Balloon Galaxy Model Observations Center of the Universe Balloon Model Raisin Bread Galaxy Model Observations Raisin Bread Universe 1. : The origin of the universe remains one of the greatest questions in science.
The discovery of cosmic microwave background radiation constitutes a major development in modern physical cosmology.In 1964, US physicist Arno Allan Penzias and radio-astronomer Robert Woodrow Wilson discovered the CMB, estimating its temperature as 3.5 K, as they experimented with the Holmdel Horn Antenna. Use the permanent marker to make four to six small dots on one side of the balloon. The January 2008 Popular Astronomy carried a project in which you mark a balloon with galaxies, then blow up the balloon so that the galaxies expand away from each other, just as in the expanding Universe. Microwave Background Radiation and an Expanding Universe Name: Section: Course: Date: Your instructor has provided you with a balloon to represent the Universe. as the balloon expands the dots get further apart, representing the galaxies moving apart . expanding universe school observatory . These and future experiments not only help confirm that the universe inflated dramatically, but are providing theorists with the first clues about the exotic forces that drove space and time apart. Materials needed include a balloon, ruler, paper strip, a copy of this page, and a marker. Testing Your Balloons in the Cold Area. . The Expanding Universe: Balloon Model. Hypothesis (an educated prediction of what is going to happen and why) If a balloon can be a model of the expanding universe, then the locations marked on the balloon will _____ as the balloon is inflated, because _____ This is beacause gases contract in colder environment and they expand in warmeer environments. Alternatively, draw several dots on a balloon with a felt pen. Alternatively, draw several dots on a balloon with a felt pen. In this chemistry science fair project, you'll investigate these changes in average kinetic energy by using a different kind of balloona latex balloon, which is able to expand and contract as the force and frequency of the elastic collisions change with temperature. The common analogy of an expanding balloon illustrating the expansion of the universe probably helps fuel this misconception. Hubble's constant is approximately \ (2.3\times 10^ {-18}s^ {-1}\) if the distance is in metres and the speed in metres per second. An excellent closing activity may be to ask them how their experiments relate to our spatially 3-dimensional Universe. The surface of the balloon will represent space. Now begin to blow up the balloon. 3. They are . Before students begin the lab, you should let students know that, ultimately, they are about to examine what happens in a 1-dimensional Universe as it expands. 5. to the notion of the expanding universe and the Big Bang. The discoveries hail from the Balloon-borne Large Aperture Submillimetre Telescope (BLAST), which . Perlmutter, 52, a professor of physics at the University of California, Berkeley, and a faculty senior scientist at Lawrence . Take a deflated balloon and draw three dots on it, and label them 1, 2, and 3. experiment, you'll create a simple model to learn how the universe expands over time. This is what we call redshift, where something happens to make the wavelength of your light longer and lower in energy. Let's go back in time to the start of the universe and recreate the expansion! A new map of the early Universe has reinforced a long-running conundrum in astronomy over how fast the cosmos is expanding. Record the distances in the table as "Balloon Circumference # 1." Measure the balloon's circumference as well 4) Inflate the balloon so that its diameter is about 10 cm bigger ( 20 cm total). In sum, students will be using elastic with sewed-on sequins to model an expanding universe. 5.7 Data on the spectral distribution of the cosmic microwave radiation obtained from the COBE satellite experiment. If you can only put one balloon in at a time, this step will take 3 hours. the receding velocity of the labeled point relative to the reference point drops.
In this activity, students use rulers to measure distances between hypothetical galaxies and then use these distances to calculate the velocities of the galaxies.
The ACT is the first ground-based CMB experiment that could have challenged Planck's results, says Erminia Calabrese, a cosmologist at Cardiff University, UK, who led the analysis of the data. Pick four of the circles around the balloon and label these A, B, C, and D. Hypothesize what will happen to the distances between the labeled circles when you . Results released yesterday came from the radiation data captured by the first MAXIMA. You will place several dots on the balloon to represent galaxies and you will blow the balloon up in several Stages. Scientists led by Konstantinos Migkas at the University of Bonn in Germany analyzed data on x-rays released by hundreds of clusters of galaxies, revealing that the universe seems to be expanding. This is a simple, but fun lab to do about the expanding universe.
So the change in entropy of the universe, or S universe is a sum of the change in entropies of these individual components, assuming there is only energy exchange between water and air. . Waves (Classical Equation of . Reset image size Figure 5. Why so quiet at LHC? The theory of inflation predicts a period of rapid expansion of the early Universe and a "flat," or ordinary, geometry for the Universe, in addition to the fine scale variation in temperature. 1. ExpandinG Balloon UniversE Name: Lab partners: (credit: This lab was inspired by the University of Washington lab. Help your children put the vinegar into the flask using a pipette or small measuring cup. However, a recent discovery involving . Waves (Classical Form) 4. XL-Calibur reaches to higher X-ray energies, 15-80 kilo-electron volt per light particle (photon), compared to IXPE's 2-8 kilo-electron volt. You may want to consult or give out the background articles on galaxies and the universe from The Universe at Your Fingertips disk. When expressed as a function of cosmic time, H ( t ), it is known as the Hubble Parameter. The first law states that an object at rest tends to stay at rest and an object in motion tends to stay in motion, both unless the object is acted upon an outside force. The results show that the farther away a dot is from the home dot, the faster its movement. With a partner, pick a balloon. The data collected using a telescope in . The balloon is marked with a waveform repre- senting a light wave. The other way is to reduce the tension of the skin. Expanding Universe Experiment. The balloon represents the big bang theroy by showng constant expansion of the objects in space. to make 10 - 15 dots on the balloon and number 10 of them after the balloon is partially inflated. When the balloon is filled with the baking soda, carefully remove it from the funnel. Then think back to the balloon analogy for the expanding universe. This activity can be in conjunction with, or independently . Science. Equipment Needed Describe the motion of these galaxies (each raisin represents a galaxy in the bread model) relative to one another. 4. end of the balloon down and paper clip it so that no air escapes. Physicists have known the universe is expanding for years, but in the late 1990s, observations made it clear that the universe was not just growing larger but doing so at an accelerating rate. In this activity, students use rulers to measure distances between hypothetical galaxies and then use these distances to calculate the velocities of the galaxies. The current WMAP results show the Hubble Constant to be 71.0 2.5 (km/sec)/Mpc. If the universe were closed, the brightest spots would be greater than one degree across. Group members should decide on . Subjects. The balloon will represent the universe. Place an un-inflated balloon on the table. To understand how the redshift of galaxies is due to the expansion of the Universe, try the following experiment. But the balloon still has a center. Step 2 : Making the Measurements. The universe has 4 dimensions: height, width, depth, and time. Record these measurements as "Balloon Circumference # 2" in the table. The inverse of the Hubble Constant is the Hubble Time, tH = d / v = 1/H o; it reflects the time since a linear cosmic expansion has begun . Modeling the Expanding Universe Activity H9 Grade Level: 8-12 Credit: ACT Collaboration. Take a balloon and mark different points on balloons like galaxies are there in the universe. Your teacher will divide the class into pairs.
vinegar! When recent satellite data and those from balloon -borne experiments are combined, a very exact t
In this activity, you are going to create a model of the expanding Universe. The false-color image shows subtle fluctuations in the temperature of the hot plasma which filled the universe before expansion cooled the material, producing the familiar stars and galaxies. For decades, scientists have been conducting a series of Earth-based and space-based experiments to measure the rate of expansion of the Universe. Don't tie it off. Make a model for the expanding universe. 2. So, what was a miniscule distance of 380,000 light years back then turned into the enormous distance of 13.7 billion light years as of today . In astronomy and observational cosmology, the BOOMERanG experiment (Balloon Observations Of Millimetric Extragalactic Radiation ANd Geophysics) was an experiment which measured the cosmic microwave background radiation of a part of the sky during three sub-orbital (high-altitude) balloon flights. some believed the results could just have been down to a scientific glitch.
