The type 1a supernova (SN) measurements are the very best evidence for an expanding universe. a … There is considerable evidence our universe is expanding.

What might be causing the universe to accelerate?

This is an irrefutable fact about our Universe, and can only be explained by an expanding Universe. The expansion of the universe is the increase in distance between any two given gravitationally unbound parts of the observable universe with time. Detection of the cosmic microwave background (CMB) b. spectra of most galaxies showed red-shifts Hubble and Humanson's observations of galaxies in the 1920's found the surprise that:

quintessence. Almost all astronomers agree on the theory of the Big Bang, that the entire Universe is spreading apart, with distant galaxies speeding away from … In 1920 Edwin Hubble photographed different galaxies and studied their spectrum. But there is also direct evidence that the universe was once smaller than it is now. The Big Bang supports interpreted observational evidence of the Cosmic Microwave Background Radiation (CMBR) barrier that there is an evolutionary expansion of the universe which promotes a … a. This presentation takes the audience through humanity’s changing view of the universe. Based on the galaxies found in the Local Group of galaxies, the most common type of galaxy in the universe is expected to be? Which of thes facts is best supporting evidence that the universe is expanding? Does the space taken up by matter also expand as the universe expands? We need you to answer this question! Explanation: He found the red shifts of galaxies and for more distant galaxies showing higher red shifts..This is the proof of expansion of universe. Expanding universe In the 1920s, astronomer Edwin Hubble discovered the universe was not static. What observational evidence supports the fact that our universe is expanding? Technically, neither space nor objects in space move. Hubble showed that, in our expanding universe, every galaxy is rushing away from us with a speed which is in direct proportion to its distance, known as Hubble’s Law, so that a galaxy that is twice as far away as another is receding twice as fast, one ten times as far away if receding ten times as fast, etc. a possible form of dark energy that can change in strength as the universe ages. In 1998 two independent projects (the Supernova Cosmology Project 10 and the High-z Supernova Search 11 ) announced not only was the universe expanding but also accelerating. Discovery of quasars c. Redshift of galaxies d. Evolution of galaxies with distance supercluster. big rip. The accelerating expansion of the universe is the observation that the expansion of the universe is such that the velocity at which a distant galaxy is receding from the observer is continuously increasing with time.. What observational evidence supports the fact that our universe is expanding? It is an intrinsic expansion whereby the scale of space itself changes.The universe does not expand "into" anything and does not require space to exist "outside" it. Actually It was Edwin Hubble who found and took images of galaxies inorder to study its whole spectrum, hence hubble found Red shifts of galaxies and also the far distant galaxies which was showing higher and higher red shifts and then supernovas was also studied by him, which showed the evidence of universe accelerating along with expansion, which was due to dark energy
