But how can a charged capacitor warp space? I thought only matter could warp space?

I don't understand physics to any degree, but I was under the assumption that EM fields also warped space (albeit orders of magnitude less). I found some explanations that are way above my head on Quora:

[2] http://www.quora.com/Physics/Can-a-large-energy-field-other-...

The second seems to suggest that energy fields, in general, do warp space.

considering e=mc2, it's not surprising that matter and energy can both accomplish the same thing - they are the same thing

Not matter. Energy. Energy warps space. Matter is just a kind of energy.

But all energy warps space, and has a gravitational field.
