It is possible that someday astronomers will measure all the distances of the 100 billion galaxies in the universe.
Lol. No honey the answer is true. :)
Someday astronomers may have measured all the distances of 100 billion galaxies in the observable universe.

You can measure very large distances, such as the size of the observable universe or distances between galaxies, using yottameters. This unit of measurement is rarely used in practical applications due to its extremely large scale.
A light year is the distance that light travels in a year. We use it because it allows us to measure huge distances.
Because, if we continued to measure the distances between star in miles, the numbers would be huge. One light-year is approximately equal to 5,865,696,000,000 miles !
Light years are a unit of distance that represents how far light travels in one year, approximately 5.88 trillion miles (9.46 trillion kilometers). They are used to measure vast distances in the universe, such as the spaces between stars and galaxies, because these distances are often too large to be conveniently expressed in miles or kilometers. For example, when astronomers say a star is 4 light years away, it means that light from that star takes 4 years to reach Earth. This method allows for a clearer understanding of the scale of the universe.
you would measure distances in centimetres, metres and kilo metres.
The concept of a day may not apply at the edge of the universe due to various factors like extreme distances, gravitational forces, and unknown phenomena. Time can also be influenced by the expansion of the universe, making it difficult to measure a conventional day as we do on Earth.
