How long would it take to travel the observable universe?

Posted on May 11, 2021 by Author

How long would it take to travel the observable 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 travel at 90\% speed of light?

Luckily for all of us, NASA addresses these in a recently-released animed video that covers all the basics of interstellar travel! To summarize, according to the immutable laws of physics (specifically, Einstein’s Theory of Special Relativity), there’s no way to reach or exceed the speed of light.

How long does it take to travel a light year at the speed of light?

A light year is the distance that light travels in vacuum in one year, about 6 trillion miles or 10 trillion kilometers. One might therefore conclude that in order to travel one light year at one tenth the speed of light, this trip would take 10 years.

How far away is 1000 light years?

European astronomers have found the closest black hole to Earth yet, so near that the two stars dancing with it can be seen by the naked eye. Of course, close is relative on the galactic scale. This black hole is about 1,000 light-years away and each light-year is 5.9 trillion miles (9.5 trillion kilometers).

How long would it take to travel to the end of the universe?

Now, if you have been doing the math, you’d see that even going that close to the speed of light, the trip to the edge of the universe would take billions of years! Since human beings are mortal, it would be impossible to even survive the trip, right?

How far can we see the universe?

We can’t see that far, but we can detect the traces left behind and draw conclusions, which makes it “observable”. In other words, our observable universe is roughly 93 billion light-years in diameter, but even if you traveled for 93 billion miles at the speed of light, would you be able to get there?

How long would it take to travel to the closest galaxy?

Thank you for you greatly, appreciated, time. The closest galaxy is the recently discovered Canis Major dwarf galaxy, which is “only” 25,000 light-years away. So it would take 25,000 years to get there if you traveled at the speed of light. Actually, that’s the amount of time it would take from the perspective of the outside world.

What is the maximum distance we can travel in light years?

If you define the edge of the Universe as the farthest object we could ever reach if we began our journey immediately, then our present limit is a mere distance of 18 billion light-years,…
