big bang: This is the big bang theory
It is called the Big Bang.
They are called astronomers.
Astronomers, physicists
The big bang theory does not state that "the universe began with a gigantic explosion." The theory suggests that our universe originated from an infinitesimally small point called a singularity. Since all of space was all localized within this point, the rapid expansion of the universe isn't an explosion. An explosion occurs within space, but the expansion of space itself isn't an explosion. Quite simply, there isn't anything outside of space for the universe to explode into. Thus the "big bang" wasn't big, nor did it go bang. Around the time of the big bang (about 13.7 billion years ago), the universe was much hotter and expanding very rapidly (somewhat analogous to an explosion but by no means an actual explosion).

The Big Bang BIG BANG was formed in 13.8 billion years ago when the universe began as a tiny, dense, fireball that exploded. Most astronomers use the Big Bang theory to explain how the universe began.

There are several pieces of evidence for dark matter. For example: * Our galaxy, and many other galaxies, rotate way too fast for the amount of known matter. * Evidence from gravitational lensing.
