How long is 13 billion light-years away?
No, because it would be beyond the bounds of our observable universe.about 46.5 billion light years

So the furthest out we can see is about 46.5 billion light years away, which is crazy, but it also means you can look back into the past and try to figure out how the universe formed, which again, is what cosmologists do.94 Billion Light Years

Size: 94 Billion Light Years. The most distant objects in the Universe are 47 billion light years away, making the size of the observable Universe 94 billion light years across. How can the observable universe be larger than the time it takes light to travel over the age of the Universe

How many galaxies can we see : One such estimate says that there are between 100 and 200 billion galaxies in the observable universe. Other astronomers have tried to estimate the number of 'missed' galaxies in previous studies and come up with a total number of 2 trillion in the universe.

Can we see 14 billion light years away

Its observable limit, for us, is the distance 46.5 billion light years in any direction. But forget “limit.” We cannot see anything from anywhere near this distance. Beyond 14.5 billion light years away (the Hubble distance), light in this expanding universe moves only away from us, not towards us.

Can we see 15 billion light years away : It's been 13.8 billion years since the Big Bang, which might lead you to expect that the farthest objects we can possibly see are 13.8 billion light-years away. But not only isn't that true, the farthest distance we can see is more than three times as remote: 46.1 billion light-years.

We know that light takes time to travel, so that if we observe an object that is 13 billion light years away, then that light has been traveling towards us for 13 billion years. Essentially, we are seeing that object as it appeared 13 billion years ago.

5.88 trillion miles

Light-year is the distance light travels in one year. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.

Is space infinite

Cosmologists aren't sure if the universe is infinitely big or just extremely large. To measure the universe, astronomers instead look at its curvature. The geometric curve on large scales of the universe tells us about its overall shape. If the universe is perfectly geometrically flat, then it can be infinite.5.88 trillion miles

Light-year is the distance light travels in one year. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.The observable universe is certainly finite, and indeed we know approximately how large it is. It's very large—literally incomprehensibly so to human intuition, in fact—but still finite. Current cosmological evidence suggest the entire universe is isotropic, spatially flat, and infinite.

You may think that you need a telescope to be a stargazer, but that's not true. There are lots of amazing things you can see with nothing but your eyes, such as constellations, planets, the Milky Way, meteor showers, zodiacal light or even the aurora borealis (northern lights).

How long would it take to go 13 billion light-years : We know that light takes time to travel, so that if we observe an object that is 13 billion light years away, then that light has been traveling towards us for 13 billion years. Essentially, we are seeing that object as it appeared 13 billion years ago.

Can we see past 13 billion light years : No. The universe is 13.8 billion years old. Its observable limit, for us, is the distance 46.5 billion light years in any direction.

How long would it take to go 13 billion light years

We know that light takes time to travel, so that if we observe an object that is 13 billion light years away, then that light has been traveling towards us for 13 billion years. Essentially, we are seeing that object as it appeared 13 billion years ago.

To spot this galaxy, astronomers used the powerful gravity from the massive galaxy cluster MACS J0647+7015 to magnify the light from the distant galaxy; this effect is called gravitational lensing.Specifically, the distance light travels in one year's time, and the time is a year on earth. So a light year is always a year on earth. One lightyear is one year on earth. Forty lightyears is forty years on earth.

Will space ever end : Current observations suggest that the expansion of the universe will continue forever. The prevailing theory is that the universe will cool as it expands, eventually becoming too cold to sustain life.
