Is the sun expanding or contracting?
The sun is actually expanding. As it ages, the sun is gradually running out of hydrogen fuel in its core, causing it to fuse hydrogen in a shell surrounding the core. This expansion will eventually lead to the sun becoming a red giant in its later life stages.
If all galaxies began to show blue shifts what would this change indicate about the fate of the univerese?
If all galaxies began to show blue shifts, it would indicate that the universe is contracting. This could suggest that the universe might eventually end in a "Big Crunch" scenario, where all matter collapses in on itself.
How did Einstein's Theory of Relativity lead to the development of the Big Bang Theory?
In 1924, Alexander Friedman noted that the equations of general relativity have only two solutions: an expanding universe or a contracting universe. Independently of that work, in 1927 Georges LeMaitre used those same equations to show that an expanding universe was the only reasonable description of our Universe. His ideas were later described as a "big bang" by those who opposed them.
Will the universe ever begin to contract?
Current scientific understanding suggests that the expansion of the universe is accelerating rather than contracting. However, there are theories, such as the Big Crunch, that propose a contraction in the distant future. More research is needed to determine the ultimate fate of the universe.
What does it mean when someone says the universe is expanding?
Two answers from me. 1. There is more room for possibilities. 2. The big bang theory and how it all went from one little speck to the universe. The discovery channel actually had a show on this once.
What does red shift of the universe show is us?
universe is expanding at an accelerated rate.
The redshift of light from distant galaxy provides evidence that the universe is?
Expanding. The redshift of light from distant galaxies is a result of the expansion of the universe causing a shift towards longer wavelengths. This supports the idea that the universe is not static but rather undergoing continuous expansion.
How does the big bang theory support the conculsion that the universe is expanding?
Cos it is an amazing tv show

What is the name of the discoverer of the big bang theory?
Jesuit priest Georges LeMaitre was the first to use general relativity to show that an expanding universe was the only reasonable description of our Universe, the first to suggest that an expansion would have observable effects, and the first to propose that our Universe had (his words) "a day with no yesterday."
Who stated that the universe is still expanding?
Hubble did not conclude that the Universe is expanding. Hubble thought the red shift indicated a unrecognized principle of nature. Hubble's constant actually shows the universe is bounded at R=150kMpc/31 and H= c/R = 62km/s/Mpc. The increase red shift velocity indicates a decreasing universe.
Scientists' evidence for an expanding universe is called a because the light waves emitted by stars and galaxies are shifting toward the end of the visible color spectrum.?
Many objects observed in the universe show a red shift. It is believed that this red shift is caused by a Doppler effect - that is, that the objects are moving away from us at a significant fraction of the speed of light. If this is true, then it is evidence for an expanding universe.
What is significant about the red shift spectra of galaxies?
The red shift spectra of galaxies show that most galaxies are moving away from us, indicating that the universe is expanding. This observation supports the Big Bang theory, which suggests that the universe began in a state of high density and temperature and has been expanding ever since. The amount of red shift in a galaxy's spectrum can also provide information about its distance from us and its velocity.
