Was there anything before the Big Bang?

It’s possible that before the Big Bang, the universe was an infinite stretch of an ultrahot, dense material, persisting in a steady state until, for some reason, the Big Bang occured. This extra-dense universe may have been governed by quantum mechanics, the physics of the extremely small scale, Carroll said.

Was time created by the Big Bang?

The general view of physicists is that time started at a specific point about 13.8 billion years ago with the Big Bang, when the entire universe suddenly expanded out of an infinitely hot, infinitely dense singularity, a point where the laws of physics as we understand them simply break down.

Did anything matter or empty space exist before the Big Bang singularity?

The universal origin story known as the Big Bang postulates that, 13.7 billion years ago, our universe emerged from a singularity — a point of infinite density and gravity — and that before this event, space and time did not exist (which means the Big Bang took place at no place and no time).

How is a singularity possible?

General relativity predicts that any object collapsing beyond a certain point (for stars this is the Schwarzschild radius) would form a black hole, inside which a singularity (covered by an event horizon) would be formed. The termination of such a geodesic is considered to be the singularity.

Did time actually exist before the Big Bang?

Mind-Bending Study Suggests Time Did Actually Exist Before The Big Bang. According to a straightforward interpretation of general relativity, the Big Bang wasn’t the start of ‘everything’.

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.

Does time exist outside of our universe?

Similarly, time, far from being eternal, is just a property of our universe. It is possible to construct hypothetical universes that are logical and self-consistent, with no time at all, or with more than one time. So outside of our universe, time has no meaning. “Before the Big Bang” would be, by definition, outside of our universe.

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.
