Quotes About Pre-Big Bang

events before the big bang can have no consequences, so they should not form part of a scientific model of the universe.

You can't get to a time before the Big Bang because there was no time before the Big Bang. We have finally found something that doesn't have a cause, because there was no time for a cause to exist in.

As far as we are concerned, events before the big bang can have no consequences, so they should not form part of a scientific model of the universe. We should therefore cut them out of the model and say that time had a beginning at the big bang.

What came before the Big Bang? According to the no-boundary proposal, asking what came before the Big Bang is meaningless—like asking what is south of the South Pole—because there is no notion of time available to refer to. The concept of time only exists within our universe.

I love existing in pre big bang conditions.

The scientific issues that engage people most are the truly fundamental ones: is the universe infinite? Is life just a sideshow in the cosmos? What happened before the Big Bang? Everyone is flummoxed by such questions, so there is, in a sense, no gulf between experts and the rest.

We don't know what triggered the big bang, nor what, if anything, existed before it. But somehow the universe emerged as a vast sea of ultrahot gas, expanding fast in all directions like the fireball ignited by a nuclear bomb blast or by the explosion of a gas pipeline. Except that the big bang was not destructive (so far as we know). Instead, it created everything in our universe, or rather the seeds for everything.

It's also important to understand that the universe did not emerge from existing material but from nothing—there was no matter before the Big Bang. In fact, chronologically, there was no "before" the Big Bang because there are no "befores" without time, and there was no time until the Big Bang.
