What made the Big Bang happen?

Answer 1

Scientists have speculated that the separation of the strong force from the electro-nuclear force caused it. But you have to think of it this way... time might have not existed before the big bang so could anything cause it... ?

Answer 2

Jesuit priest Georges LeMaitre first proposed Big Bang Cosmology when he noted that the equations of General Relativity do not permit our Universe to be eternally stable -- it must be either expanding or contracting. Since LeMaitre also had trouble visualizing a Universe that has been contracting for eternity, he surmised that our Universe must be expanding. This led him to conclude that our Universe once had (his words) "a day with no yesterday." LeMaitre correctly surmised that the red shift of distant "nebulae" would be explained by this expansion; Edwin Hubble showed that these nebulae were actually galaxies, and that red shift was pretty much as LeMaitre had predicted.

Answer 3

The Big Bang theory states that the universe began as a singularity, a point of infinite density and temperature. The exact cause of the Big Bang is still not fully understood, as it is difficult to probe the conditions of that moment. It is believed that some unknown event or process triggered the rapid expansion of the universe.

Answer 4

God said,"Let there be light!"And BANG! There was light.
