What is the size of the universe in kilometers?

Answer 1

#2.6 X 10^26 km=0.26# billion billion billion km or more

The cosmos has infinite directions. Presuming that our universe's center

The universe is almost twice as big as us, and it is located 13.8 billion light years (ly) away.

In km, this is #27.6 X 10^9 ly#
#= (27.6 X 10^6)(365.26 X 24 X 60 X 60)# light seconds (ls)
#= 8.7 X 10^17 ls = (8.7 X 10^17)(299792456)# km
#= 2.6 X 10^26# km.

The size may be greater if galaxies exist outside of Milky May.
