How did the universe start timeline?

We start out with the beginning of everything – the Big Bang, which gave rise to the Universe 13.8 billion years ago. Fast-forward to 10.4 billion years ago, and the Universe achieves habitability for the first time, and life is finally given a chance to emerge.

Does the universe end?

It never ends, but it’s also constantly expanding. Scientists don’t think there is a true edge of the universe. This is called the edge of the observable universe. It’s the farthest we can see, based on how we get information from light.

How old is our universe?

The universe is (nearly) 14 billion years old, astronomers confirm. With looming discrepancies about the true age of the universe, scientists have taken a fresh look at the observable (expanding) universe and have estimated that it is 13.77 billion years old (plus or minus 40 million years).

How many universes are there?

There are still some scientists who would say, hogwash. The only meaningful answer to the question of how many universes there are is one, only one universe.

When did time begin?

The cosmos is only so old, and light only travels so fast. The current width of the observable universe is about 90 billion light-years.

Where did all matter come from?

Origins. In the first moments after the Big Bang, the universe was extremely hot and dense. As the universe cooled, conditions became just right to give rise to the building blocks of matter – the quarks and electrons of which we are all made.
