How far does the universe reach?

about 46.6 billion light-years
Since the universe has been expanding for 13.8 billion years, the comoving distance (radius) is now about 46.6 billion light-years.

How many miles is it to the edge of the universe?

It’s about 238,855 miles on average, and I say on average, because the distance does change.

Is there a limit to how big the universe can get?

There’s a limit to how much of the universe we can see. The observable universe is finite in that it hasn’t existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).

How far have we Travelled in space?

The record for the farthest distance that humans have traveled goes to the all-American crew of famous Apollo 13 who were 400,171 kilometers (248,655 miles) away from Earth on April 14, 1970. This record has stood untouched for over 50 years!

How big is the universe, and how do we know?

We know the size of the observable Universe though. That has a diameter of approximately 93 billion light years (28 billion parsecs). And that, in itself, is a tremendously huge distance. But, for all we know, the actual Universe could be much bigger (even infinite).

What are the biggest things in the universe?

Most astronomers agree that the biggest thing in the universe is the cosmic web. It’s an endless scaffolding of clusters and superclusters of galaxies surrounded by dark matter and resembles a three dimensional spiderweb.

What is the estimated diameter of the universe?

The diameter of the observable universe is estimated at about 28 billion parsecs (93 billion light-years), putting the edge of the observable universe at about 46–47 billion light-years away. All electromagnetic radiation, and also gravitational waves, all of which are limited to the speed of light.

How big was the universe just before the Big Bang?

Most physicists, he begins, agree on the big-bang theory, which says that 14 billion years ago the entire observable universe was “roughly a million billion billion times smaller than a single atom” and has been expanding ever since, to its current size of something like 100 billion galaxies.
