# How long would it take to travel 13 billion light years?

## How long would it take to travel 13 billion light years?

To travel 13.3 billion light-years from Earth, Voyager 1 would then take 228,900 years to do so.

Can we see 14 billion light years away?

The most distant parts of the Universe are only visible in the early stages. In fact, anything further away than about 4,300 Mpc (or 14 billion light years) today is at the limit of what we can reach at the speed of light.

How far away is 1 billion light years?

The supercluster is about 1 billion light years away. A plot of the entire sky of the 60,000 brightest galaxies shows how galaxies clump together into large supercluster formations.

What was there 13 billion years ago?

Scientists believe that everything in the Universe started around 13 billion years ago with a giant explosion called the Big Bang. For billions of years since the explosion, the Universe has grown and cooled, while matter has formed into galaxies, stars and planets.

How old is our universe?

14 billion years
The universe is (almost) 14 billion years old, confirm astronomers. With discrepancies looming over the true age of the universe, scientists have taken a fresh look at the (expanding) observable universe and have estimated it to be 13.77 billion years old (roughly 40 million of years).

How old is the earth?

4.543 billion years old
Earth/Age

The Earth is estimated to be 4.54 billion years old, more or less around 50 million years old. Scientists have scoured the Earth for the oldest rocks to be radiometrically dated. In northwestern Canada, they found rocks about 4.03 billion years old.

#### How many light years are there in a year?

The answer seems obvious: 13.8 billion light-years, since a light-year is the distance that light can travel in a year, and nothing can go faster than that. Unfortunately, like many of the answers that seem obvious when you apply your logical common sense to them, that’s not how things actually work.

How big is 13.8 billion light-years?

But 13.8 billion light-years is far too small to be the right answer. In reality, we can see 46 billion light-years in all directions, for a total diameter of 92 billion light-years.

How old is the universe in light years?

The universe is almost 14 billion years old but remember the rate of expansion is faster than the speed of light (in general relativity this does not violate the laws of physics) so cosmic space detectable is actually larger than this number in light-years or parsecs.

## How many light years away is the Milky Way?

At 4 billion light-years away, we can now see it as it was 13.4 billion years ago. It’s only 400 million years after the big bang. It is one of the first galaxies ever formed in the universe.
