Did time and Space begin with the Big Bang?

Did time and Space begin with the Big Bang?

For 13.8 billion years, the universe has been expanding, cooling and evolving. Textbooks often say that the start of this expansion — the Big Bang — was the start of time. “Others don’t use the inflationary mechanism but still have a phase which is before the Big Bang — before the conventional expanding phase.”

Does the Big Bang theory have a beginning?

The Big Bang might not be the very beginning of the Universe itself, but it is the beginning of our Universe as we recognize it. It’s not “the” beginning, but it is “our” beginning. It may not be the entire story on its own, but it’s a vital part of the universal cosmic story that connects us all.

Could time have started with the Big Bang?

But in our quest for the beginning, we know already that time couldn’t have started with the Big Bang. In fact, it might not have had a beginning at all. radiation in a rapidly expanding state.

Is the Big Bang a valid explanation of the universe?

The full suite of data, including the observations of the light elements and the cosmic microwave background, leaves only the Big Bang as a valid explanation for all we see. As the Universe expands, it also cools, enabling ions, neutral atoms, and eventually molecules, gas clouds, stars, and finally galaxies to form.

Did the universe begin with a whimper or a bang?

But we know better today. The Universe began not with a whimper, but with a bang! At least, that’s what you’re commonly told: the Universe and everything in it came into existence at the moment of the Big Bang.

What happens when the Big Bang comes to an end?

And finally, when this phase of the Universe — this period of inflation — came to an end, that energy would get converted into matter-and-radiation, creating the hot, dense state synonymous with the Big Bang.
