Space and time appear at the Big Bang singularity, so questions of what happens "before" the Big Bang are not well defined. As far as science can tell, there is no before; the Big Bang is the ...

You may think that time started 13.8 billion years ago at the birth of the universe, but physicists with alternative definitions of time have other ideas ...

New research suggests black holes may transition into 'white holes', ejecting matter and potentially even time back into the universe, defying our current understanding of these cosmic giants.

Extrapolating this cosmic expansion backwards in time using the known laws of physics, the theory describes an increasingly concentrated cosmos preceded by a singularity in which space and time lose ...

Our current understanding of the universe is based on the Big Bang model. The model proposes that approximately 13.8 billion years ago, the universe came into existence as a singularity and ...

Although the new model resolves the singularity problem mathematically ... inflation — the rapid expansion that followed the Big Bang — evidence of these changes might be imprinted in ...

“There are very energetic processes in the universe going back to the big bang singularity. We have the opportunity to discover something fundamental about the universe.” Other astronomical ...
