Re: Question about gravity (curved space?)

The essential aspect of gravity in GR is that spaceTIME is curved. In
plotting the trajectory of a small object in spaceTIME, its velocity
becomes an angle in the corresponding space-time plane, and naturally
affects the path of the object.

Hi,

I was wondering, if gravity curves space, then why does it matter how
fast you move through this space?

If it's only curved, the speed at which something moves through it
shouldn't make a difference on it's angle should it? If it would,
wouldn't that mean there's inertia which would be strange if space
itself was curved (ie something moving through it would have to think
it's going straight).

I'm probably just missing something but couldn't find an answer.
