Question

What is the farthest place from earth ?

Answer 1

Hint: The farthest place from the earth is measured in light years. For expressing distances to stars and other distances on a universal level, the light-year is most often used. Measuring distances in miles or kilometres isn't enough on the size of the universe.

Complete answer:
A light-year is a unit of space rather than time. A light-year, or $6$ trillion miles, is the distance travelled by a ray of light in a single Earth year ( $9.7$ trillion kilometers). Since the universe is $13.8$ billion years old, the "edge" of the universe could be $13.8$ billion light years away if light travels at the highest possible distance.The universe, on the other hand, is expanding in the same manner as space itself is expanding, because light travelling towards us from afar is like going down an escalator.

As a result, the universe's farthest place from the earth, potentially visible objects have travelled somewhat further away after they released light $13.8$ billion years ago. The radius of the known universe is currently estimated to be $46.5$ billion light years.The visible universe's edge which is the farthest place from the earth is estimated to be $46.5$ billion light years far.

Note: The Hubble Space Telescope of NASA has detected the farthest individual star ever seen: an immense blue celestial body known as Icarus, which is situated over halfway through the world. The star, which is located in a faraway spiral galaxy, is so far away from Earth which means its light takes nine billion years to reach us.
