To any observer in the universe, it appears that all but the nearest galaxies ...
In the case of accelerated expansion, ¨ is positive; therefore, ˙ was smaller in the past than today. Thus, an accelerating universe took a longer time to expand from 2/3 to 1 times its present size, compared to a non-accelerating universe with constant ˙ and the same present-day value of the Hubble constant. This results in a larger light ...

The prevailing theory is that the universe will cool as it expands, eventually becoming too cold to sustain life. For this reason, this future scenario once popularly called "Heat Death" is now known as the "Big Chill" or "Big Freeze".
Something is changing the expansion rate of the universe, scientists have said. For decades, researchers have been attempting to measure the “Hubble constant”, or the speed at which the cosmos ...
Physical cosmology. The Big Crunch is a hypothetical scenario for the ultimate fate of the universe, in which the expansion of the universe eventually reverses and the universe recollapses, ultimately causing the cosmic scale factor to reach zero, an event potentially followed by a reformation of the universe starting with another Big Bang.
