Space wtf is it?

Those graphs are bullshit, but documentaries insist on using them.

Consider them graphs of the apparent gravitational force between the bodies at distance between the bodies.

Getting this baited

People often say that space is nothing but the existence of dimensions is hardly 'nothing'. Space is an unique type of stuff despite what Veeky Forums tells me.

What's hard to understand? Matter/Energy curves space-time. In the curved space-time, a body without a force acting on it travels along geodesics (which happen to be ellipses in this case) in the same way it would travel along straight lines in usual space-time.

t. non-brainlet who knows next to nothing about GR

Just so that you know. IF you really want to understand gravity as it is seen by today sphysics....
You need to read ART and understand it....
its a long way.

>curves
In which direction?

what the fuck am i reading

Don't let them fool you. Space and time are abstractions (without physical existence) we use as descriptors in our models. As soon as you ascribe properties to space you are talking about the primal medium, historically called ether (not to be confused with the material aether). www-groups.dcs.st-and.ac.uk/history/Extras/Einstein_ether.html

Yep. Definitely due to electromagnetism

>haha guys space and time are relative
>just kidding spacetime has properties and bends around matter and energy

Which is it?
