Question

how big is the universe in numbers

Expert Solution

Step 1

The universe is made up of all of space, time, and everything that exists within them, including all of the planets, stars, galaxies, and other types of matter and energy.

The prevailing cosmological explanation for the universe's formation is the Big Bang theory. The universe has been expanding ever since the Big Bang, which occurred $13.787 \pm 0.020$ billion years ago, according to this theory. While it is uncertain how big the entire universe is in terms of space, it is possible to calculate the size of the observable universe, which has a current diameter of about 93 billion light-years.
