It’s infinitely infinite

Time isn't linear. As light travels through light years in space it can slow or increase it's speed. Time is definitely relative given nuances of size, distance, gravity of black holes etc. This isn't to say that we can go back in time, but we can definitely accelerate.

That and our outer space has another ' outer space' beyond it. Which is hard for us to explain because it doesn't have the qualities of time, space, and matter like we're used to thinking of reality in.

Outer space may actually be inner space it has been theorized that our universe exists within a black hole.

I don’t know the veracity of this theory so it’s not really a fact but the fact that it may be possible is fascinating.

There are pieces of black holes that are as small as an Adam, and have gone straight through the Earth, causing an explosion when they hit.
