Question: Can You See A Galaxy 20 Billion Light Years Away?

What is the farthest we can see into space?

The farthest that Hubble has seen so far is about 10-15 billion light-years away.

The farthest area looked at is called the Hubble Deep Field..

What is past the edge of the universe?

As far as we can tell, there is no edge to the universe. Space spreads out infinitely in all directions. Furthermore, galaxies fill all of the space through-out the entire infinite universe. This conclusion is reached by logically combining two observations.

How old is our universe?

13.7 billion yearsMeasurements made by NASA’s WMAP spacecraft have shown that the universe is 13.7 billion years old, plus or minus about 130,000 years.

How can you see 46 billion light years?

1.) Stuff is everywhere, and light travels at the speed of light. … So after 13.8 billion years, you’d expect to be able to see back almost 13.8 billion light years, subtracting only how long it took stars and galaxies to form after the Big Bang.

What is the oldest thing we can observe in the universe?

The search for extremely distant galaxies continues today. Astronomers have confirmed the discovery of one the oldest and most distant objects ever known in the universe — a star-forming galaxy 12.8 billion light-years away that started forming within a billion years of the Big Bang that kickstarted everything.

How far have we seen in the universe?

They become abstract, conceptual — so much larger than any human experience. So the age of the universe just seems like a number, but it’s a very big number: roughly 13.8 billion years. That means the “edge” of the universe is 13.8 billion light-years away — so far away that we’ve never been able to observe it.

Why can’t we see a galaxy 15 billion light years away?

Because looking 15 billion light-years away means looking to a time before the universe existed. Why can’t we see a galaxy 15 billion light- years away? … Because no galaxies exist at such a great distance.

How old is our galaxy?

13.51 billion yearsMilky Way/Age

Will humans ever travel to other galaxies?

The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.

How far back in time can we see?

In actuality, we can see for 46 billion light years in all directions, for a total diameter of 92 billion light years.

Can we see 14 billion light years away?

The most distant parts of the Universe are only visible during the earliest stages. In fact, everything that’s more distant than about 4,300 Mpc (or 14 billion light-years) today is at the limit of how far we can reach at the speed of light.

Can we see the edge of the universe?

As far as we can tell, there is no edge to the universe. Space spreads out infinitely in all directions. Furthermore, galaxies fill all of the space through-out the entire infinite universe. This conclusion is reached by logically combining two observations.

Is the universe infinite?

The observable universe is still huge, but it has limits. That’s because we know the universe isn’t infinitely old — we know the Big Bang occurred some 13.8 billion years ago. That means that light has had “only” 13.8 billion years to travel.

Does space ever end?

It’s because of the shape of space. Our part of space, or the observable universe, has a special shape: it is flat. That means if you and a friend each had your own rocket ship and you both took off and travelled in a straight line, forever and forever, you would never meet.

How do we know when the universe began?

According to the standard Big Bang model, the universe was born during a period of inflation that began about 13.8 billion years ago. Like a rapidly expanding balloon, it swelled from a size smaller than an electron to nearly its current size within a tiny fraction of a second.

Could we see a galaxy that is 50 billion light years away?

Could we see a galaxy that is 50 billion light-years away? A. No, because it would be beyond the bounds of our observable universe.

What is outside the universe?

Encountering the Unknown Despite its strangeness, this first idea is one of the easiest to digest. Astronomers think space outside of the observable universe might be an infinite expanse of what we see in the cosmos around us, distributed pretty much the same as it is in the observable universe.

Where is the end of the universe?

The implication though, is that there is no “edge”; there is no place to go where the universe just ends and one could look in some direction and see what’s beyond it. One analogy often used to describe this edgeless universe is the surface of a balloon.

How far can the human eye see?

Based on the curve of the Earth: Standing on a flat surface with your eyes about 5 feet off the ground, the farthest edge that you can see is about 3 miles away.

Can we go back in time?

The Short Answer: Although humans can’t hop into a time machine and go back in time, we do know that clocks on airplanes and satellites travel at a different speed than those on Earth. We all travel in time! … And we are all traveling in time at approximately the same speed: 1 second per second.

Is it possible to see a galaxy 20 billion light years away Why or why not?

Average distances between galaxies are increasing with time. … Could we see a galaxy that is 20 billion light-years away? (Assume that we mean a “lookback time” of 20 billion years.) No, because it would be beyond the bounds of our observable universe.
