Gravity bends space?

If gravity bends space (and therefore elliptic trajectories of celestial objects), then why do comets breakup due to tidal forces? Shouldn't they glide (stretching and shrinking) through the space as it is (bent or not)?

What does it mean for space to be bent? What does it mean for objects that exist and travel through that space.

Wtf, guize, I'm confused with relativity theory and all this gravity bends space thing.

nb4 troll. please, discuss.

Space bends are an illusion produced by gravity, much like seeing a fish in water. The difference between space skews and water is mass, the skews are what we see, not what is actually effected.

Ever heard of a black hole? The explanation of POV when someone is falling into a black hole.
Person1 falling into black hole would perceive the falling into and would be unharmed.

Person 2 watching from the event horizon would see the person being ripped apart atom by atom very slowly.

It's perception! It's all about questioning perception! :P
