Question

hi what is length of our universe ​

Answer 1

hi friend

the length of universe is 13.6 billion light days but actually universe is very vast

Answer 2

Answer:

The radius of the observable universe is therefore estimated to be about 46.5 billion light-years and its diameter about 28.5 gigaparsecs (93 billion light-years, 8.8×1023 kilometres or 5.5×1023 miles).

if only the radius is this much...then you can think how large our universe is....

however, the scientists only know 5 % of the whole universe ..and the other 95 % is dark universe. which is not known by the scientist.
