Were there any universes before this one?

There was actually a universe already existing before it and the Big Bang was merely the end of that universe, said Nobel laureate Roger Penrose. He added that evidence of that previous universe can still be observed today.

What existed first in the universe?

The Big Bang is thought to have kick-started the universe about 13.7 billion years ago. At first, the universe was too hot and dense for particles to be stable, but then the first quarks formed, which then grouped together to make protons and neutrons, and eventually the first atoms were created.

Are there past universes that existed before our own?

Scientists May Have Just Found Evidence For Previous Universes That Existed Before Our Own. Scientists have claimed that evidence for past universes may exist in the night sky – namely the remnants of black holes from another universe.

What is the oldest observation we currently have of the universe?

This is the oldest observation we currently have of the universe. From 370,000 years until about 1 billion years. After recombination and decoupling, the universe was transparent but the clouds of hydrogen only collapsed very slowly to form stars and galaxies, so there were no new sources of light.

What evidence points to the beginning of the universe?

Einstein developed his theory of relativity – which was independently verified by Alexander Friedman and Georges Lemaitre. And, Edwin Hubble observed the redshift in the light from distant galaxies. But, these observations aren’t all of the science we have that points to a beginning of the universe.

What is the chronology of the universe in physical cosmology?

Physical cosmology. The chronology of the universe describes the history and future of the universe according to Big Bang cosmology. The earliest stages of the universe’s existence are estimated as taking place 13.8 billion years ago, with an uncertainty of around 21 million years at the 68\% confidence level.
