How you think the universe will end?

The Big Freeze. Astronomers once thought the universe could collapse in a Big Crunch. Now most agree it will end with a Big Freeze. Trillions of years in the future, long after Earth is destroyed, the universe will drift apart until galaxy and star formation ceases.

Is there a end to the universe?

The end result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity).

Do scientists know where the universe ends?

Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space. But nobody knows for sure.

Is the universe coming to an end?

The final basic possibility for the universe’s end is known as the Big Rip. In this scenario, dark energy — the mysterious substance that acts in opposition to gravity — pulls everything apart piece by piece. The cosmos’ expansion accelerates until distant galaxies are moving away from us so quickly that their light can no longer be seen.

What can we see in the universe?

Everything you can see, and everything you could possibly see, right now, assuming your eyes could detect all types of radiations around you — is the observable universe. In visible light, the farthest we can see comes from the cosmic microwave background, a time 13.8 billion years ago when the universe was opaque like thick fog.

What is the farthest back in the universe we can see?

In visible light, the farthest we can see comes from the cosmic microwave background, a time 13.8 billion years ago when the universe was opaque like thick fog. Some neutrinos and gravitational waves that surround us come from even farther out, but humanity does not yet have the technology to detect them.

How much longer will the universe last?

We are currently living approximately 13 billion years after the universe’s start, but, given the different scenarios for its demise, it’s unclear how much longer the universe will persist. In the first scenario — the universe bows out of existence due to heat death — all the stars in the cosmos will burn up their fuel,
