Age and Size of The Cosmos
According to current scientific theory, the cosmos began 13.7 billion years ago short scale in the Big Bang. The current diameter of the observable cosmos is thought to be about 93 billion light years.
The diameter of the entire cosmos is unknown. However, according to Alan Guth's inflation theory, the actual size of the cosmos is at least fifteen orders of magnitude larger than the observable universe. This means that if the inflation theory is correct, the 93 billion light year diameter of the observable universe is approximately as much smaller than the diameter of the entire universe as the diameter of a helium atom is compared to the diameter of the Sun. This is equivalent to a minimum diameter of the entire cosmos of 1026 light years (100 septillion light years short scale).
