How long would it take to reach the edge of the universe?

How long would it take to reach the edge of the universe?

It’s Space Day, but traveling the vast entity that is space would take far longer than a single day. The nearest galaxy: 749,000,000 (that’s 749 million) years. The end of the known universe: 225,000,000,000,000 years (that’s 225 trillion) years.

Can we reach the edge of the universe?

Unfortunately, since universe is technically expanding faster than the speed of light (due to the expansion of space between matter), it is theoretically impossible to ever reach the “edge” of the universe, since it will always be moving away faster than we could ever move towards it!

What is beyond the border of the universe?

We are not sure but can theorize what lies beyond the universe that we know. Outside the bounds of our universe may lie a “super” universe. Space outside space that extends infinitely into what our little bubble of a universe may expand into forever. Another theory is that we are creating space as our universe expands.

How far is the end of space?

It extends about 20 miles (32 kilometers) above the Earth. Floating around the atmosphere is a mixture of molecules – tiny bits of air so small you take in billions of them every time you breathe.

What happens if we reach the end of the universe?

Dark energy could still evolve, leading to a Universe that might either recollapse in a Big Crunch, expand forever, or speed up in its acceleration and eventually tear even the fabric of space apart in a catastrophic Big Rip. The different ways dark energy could evolve into the future.

Can James Webb telescope see beyond observable Universe?

Webb will be able to see what the universe looked like around a quarter of a billion years (possibly back to 100 million years) after the Big Bang, when the first stars and galaxies started to form.

How many light years is the edge of the universe?

The distance between Earth and the edge of the universe (in any direction) is about 46 Billion light years. The observable universe is thus spread across 93 Billion light years.

Why is the edge of the universe important?

This is because that “edge” is a boundary in time, rather than in space. This edge represents the limit of what we can see because the speed of light — even in an expanding Universe governed by General Relativity — only allows signals to travel so far over the Universe’s 13.8 billion year history.

Are there galaxies at the edge of the universe?

You’d never come to an edge of this flat universe; you’d only find more and more galaxies. That’s all well and good with most astronomers. A flat universe agrees with both observation and theory, so the idea now sits at the heart of modern cosmology. The problem is that, unlike a spherical universe, a flat one can be infinite — or not.

Is the expansion of the universe without an edge?

We have a complete and consistent mathematical description of the expansion of the universe using only the normal, workaday three dimensions that we know and love. So that means we can have an expanding universe without needing an edge or a thing for it to expand into.
