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?

What is it? We don’t really know it is one of the key discussions in modern physics, we can see and measure the impact, but can see what is causing it directly. https://youtu.be/3NWnSdBq5eg
