The question of what "started" the Big Bang is very much an open topic. We can't be sure that the concept of "started" even applies, since by definition there was nothing - no time, no space, no matter, and no existence - "before" the Big Bang. Or even if the concept of "before the Big Bang" has any validity.
The theory started when astronomers noticed that everything in the universe appeared to be moving away from us, more rapidly the further away it was. If you trace this backward in time, you come to the more or less inescapable conclusion that at one time, everything must have been very very close together.
If you're asking what caused the Big Bang itself ... nobody really knows.
The first peace of direct evidence came from Edwin Hubble in the 1920s. He used Doppler shift in the spectra of galaxies to discover that they were speeding away from each other. This means that the universe is expanding, as if it all started from one point. Then in 1964 came the most compelling observation, radio astronomers discovered the cosmic microwave background radiation. This is the radiation left over from the big bang 13.7 billion years ago
Because of the Red Shift. It's like the Doppler effect. He noticed that the galaxies were moving away from each other. He saw that the light from the galaxies was changing colour more from blue to red the further away they were from us.
Actually this made him think of the expanding Universe. The Big Bang idea was
developed later.
You can get more information on http://www.big-bang-theory.com/ but this is all a matter of opinion.
because it did you nooband if your reading this you suckers got served cause I'm a Muslim,not a terriost, a Muslim
Though it is credited to Edwin Hubble the origin of the idea actually came from a Roman Catholic priest that majored in physics.
Worst Show ever this show sucks its the worst nobody watches it.
