What lies before the Big Bang?
The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang and thought to have contained all the energy and spacetime of the Universe.
Why did the singularity exist?
The initial singularity was the gravitational singularity of infinite density thought to have contained all of the mass and space-time of the Universe before quantum fluctuations caused it to rapidly explode in the Big Bang and subsequent inflation, creating the present-day Universe.
What was there before the initial singularity?
For now, we can say that before singularity, there was nothing, absolutely nothing. Time and matter didn’t exist. For a moment, it is impossible to think about ‘nothing’ being there just like it is to imagine the first and second dimension.
Were there more universes before the Big Bang?
Armed with string theory, Kaku and others speculate that before our Big Bang, there were simply more universes. “Our universe could have either popped into existence or collided with another universe,” he says. Imagine a bubble bath where each bubble represents a universe.
Was Our Big Bang just a ‘bounce?
Our Big Bang, he argues, may have been just a “bounce” — a transition from an earlier, collapsing universe to the expanding one that we find ourselves in today. Roger Penrose proposed the idea of a sequence of universes evolving over time. David Levenson / Getty Images file
What is the Big Bang theory?
The Big Bang theory says that our universe began as a point of infinite gravity and density called a singularity. Then, in a trillionth of a trillionth of a trillionth of a second, it exploded outward, doubling and re-doubling and re-doubling in size at a rate faster than the speed of light in a phenomenon physicists call inflation.
What happened before there was a universe?
Before there was an Earth, there was just a big cloud of gas and dust floating out in the universe. Before there was a universe well, before that is a point that physicists spill a lot of ink over. We don’t know what happened before the Big Bang gave birth to the universe, but the smartest people in science have plenty of fascinating theories.
