If so, how, and what would it feel like, to step on something that's flatter than the natural curvature of the earth? Hmmm, if gravity is quantized then I s...

Re: Superconducting CPU?

One thing I should point out is that I *think* a superconducting CPU would be amazingly faster (for some computations). The point isn't power. The point is that your clockspeed is mostly determined by the RC (resistance time capacitance) delays in the circuit. If R drops to zero, all your gates (in...

So I've become lost on something, or rather lost on an entire part of this subject due to one question.

How can one determine how much gravity say, a photon, generates? Its energy should be relative to your velocity compared to its velocity (reference frame) so how gravity does it then have?
