It is easier to understand relativity without the effects of gravity (bent space).

That is why the easier version is refered to as special relativity... special because it refers to a flat spacetime (no gravity)... a restricted subset of the more general set of solutions.

While general relativity being the more difficult version to understand includes the effects of gravity. And by definition treats gravity as a geometric effect... in other words space is bent by gravity.

Yes, but maybe you've heard this:
Passenger: Does this train stop at Princeton?
Einstein: One might as well say - does Princeton stop at this train?

What's the difference between that and this:
- Space is bent and things move straightly through it
- Space is straight and things move through bent paths through it

Erm..just my attempt to simplify Copernican solar mechanics - look, it's easy, just think of the sun as a daisy - the corona is the petals and that bee is like, er, Jupiter but furry .... :embarassed:

OK, I'll get my coat. ~:wave:

Einstein is talking about frames of reference.

The difference between space being bent and things going in bent paths is okay from a frame of reference point of view.

From an understanding of cause and effect, it is easier to understand it from the point of view of what is causing the change... space is bent = gravity, rather then things move in bent paths because of ?.

One has a cause and effect, the other just describes the effect.
