The Observable Universe consists of all matter in our Universe that can be observed by us, with a diameter of 8.8*1026 m, 880 yottameters, or 93 billion light years.[1]

We know the Big Bang happened 13.8 billion years ago and the rate of expansion is currently accelerating. We don't know what accelerates, but we predict it is caused by Dark Energy, a type of Dark Matter.

As the time passes by, the gaps between galaxies are expanding, which means we will lose our opportunities on observing a lot of galaxies over time.
