comment How would a black hole power plant work?
Actually tiny black holes are not expected to be black while they're also tiny - which means hey have relatively low gravity, mass and volume and as such are easier to build around.

comment How would we tell antimatter galaxies apart?
@TobiasKienzler yeah, I meant electrons. Here's some reading on the difference of anti-matter (which is real) and negative matter (which is probably just sci-fi): askamathematician.com/2012/02/…

comment Since cables carry electricity moving at the speed of light, why aren't computer networks much faster?
Whaddahell? "Photons in anything else travel slower, like in your cable (0.64c)." - may I remind you it's the electrons traveling, not photons?

comment How would we tell antimatter galaxies apart?
@TobiasKienzler You're mistaking antimatter and negative matter. Anti-matter, such as positrons is matter with opposite charge. Positrons annihilate neutrons on impact. Negative matter, on the other site, would be opposite of matter - with opposite gravity. It would annihilate matter without leaving anything behind.

comment What would happen if an accelerated particle collided with a person?
If what you say is true, isn't the beam visible when passing through air at atmospheric pressure?

comment Are all machines linearly scalable?
Lazy answer is that any machine eventually collapses under it's own gravity provided it's huge enough.

comment Why is there a scarcity of lithium?
@RobJeffries agreed, as the old star collapses, the energy from the collapse is thought to be used on energy-consuming nuclear fusion.

revised North and south of magnetic field
made the image smaller and rotated it so that it better fits the text. No need to upload images that freakish big.
