FAQ: Is The Universe Infinite?

Is the universe infinite or expanding?

The universe encompasses everything in existence, from the smallest atom to the largest galaxy; since forming some 13.7 billion years ago in the Big Bang, it has been expanding and may be infinite in its scope.

Does the universe have an end?

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).

What is beyond the universe?

The universe, being all there is, is infinitely big and has no edge, so there’s no outside to even talk about. Oh, sure, there’s an outside to our observable patch of the universe. 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.

How far is the end of universe?

The comoving distance from Earth to the edge of the observable universe is about 14.26 gigaparsecs ( 46.5 billion light-years or 4.40×1026 m) in any direction. The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs (93 billion light-years or 8.8×1026 m).

Where is end of space?

No, they don’t believe there’s an end to space. However, we can only see a certain volume of all that’s out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn’t had time to reach us yet, so we have no way of knowing such a galaxy exists.

Who created the universe?

A Belgian priest named Georges Lemaître first suggested the big bang theory in the 1920s, when he theorized that the universe began from a single primordial atom.

What happens when you reach the end of space?

It will expand forever; the galaxies within groups and clusters will merge together to form a giant super-galaxy; the individual super-galaxies will accelerate away from one another; the stars will all die or get sucked into supermassive black holes; and then the stellar corpses will get ejected while the black holes

What is beyond a galaxy?

After all, our galaxy is a warped disc about a hundred thousand light-years across and a thousand light-years thick, so it’s incredibly difficult to see beyond that. But now, a new study is saying there could be extragalactic exoplanets.

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.

Can we go beyond our galaxy?

Our Galaxy, the Milky Way, is a disk of stars about 100,000 light-years across, and about 1,000 light-years thick. So, to leave our Galaxy, we would have to travel about 500 light-years vertically, or about 25,000 light-years away from the galactic centre.

What is the deadliest thing in the universe?

For one, falling into a black hole is easily the worst way to die. Halloween is a time to be haunted by ghosts, goblins and ghouls, but nothing in the universe is scarier than a black hole.

Where is the edge of universe?

At distances of 31 billion light-years, corresponding to a time of just 550 million years after the Big Bang, we reach the edge of what we call reionization: where the majority of the Universe is mostly transparent to optical light.

What is the farthest we can see into space?

“From previous studies, the galaxy GN-z11 seems to be the farthest detectable galaxy from us, at 13.4 billion light-years, or 134 nonillion kilometers (that’s 134 followed by 30 zeros),” Kashikawa said in a statement. “But measuring and verifying such a distance is not an easy task.”
