Eli5: What exactly is space-time?

453 viewsOtherPlanetary Science

So I was reading up about gravity and how objects with a bigger mass actually “bend” the fabric of space which is often called space-time. But what is it exactly?

Can we see space-time? Does it actually exist or is it just a concept/hypothetical?

Also, an article mentioned that that we need to be in the 5th dimension to actually see space-time. So, does that prove higher dimensions do in fact exist and are having an impact on our 3D world?

Gravity and Momentum are pretty much the same thing. The Earth is having an effect on your momentum because it’s great mass is distorting spacetime.
