Space is a massive place, in fact it is potentially infinite. But is it really truly infinite, or just extremely big? A new video takes a closer look at our universe, and asks the question whether it is infinite or not.
The video also gives a lot to think about. It talks about how even if you could continue to go across space forever without finding an end, it would necessarily be infinite, it would just have no edge. Think of it kind of like Earth — there is no edge to the Earth, but it’s clearly not infinite. Then again, it also notes that it’s really hard to say one way or another if our universe is really infinite.
Okay, so this whole subject is complicated, but it’s still fascinating. Check out the video for yourself:
