universe is the same everywhere on the large scale, at all
times.2 It maintains the same average density of matter forever.
There are observational evidences found that can prove the
Big Bang model is more reasonable than the Steady State model.
First, the redshifts of distant galaxies. Redshift is a Doppler
effect which states that if a galaxy is moving away, the spectral
line of that galaxy observed will have a shift to the red end.
The faster the galaxy moves, the more shift it has. If the
galaxy is moving closer, the spectral line will show a blue
shift. If the galaxy is not
