comment How would one attach black hole to starship in the Black hole Starship model?
According to wikipedia you are right about the charge but I must wonder how, how does the electro-magnetic force escapes the BH if light (electro-magnetic radiation) can not escape it?

I agree, but are thought experiments not allowed here?

comment Why do we assert Hulse–Taylor binary system's orbital decay to gravitational waves and not radiation?
You are right, but my point holds: Pulses from the companion neutron star have not been detected, but this might only be the result of an unfavorable viewing angle.

I thought chemistry is just applied physics ;)

comment Is there proof gravity bends space or is it just the most convenient explanation?
Nobody is denying that General Relativity has been experimentally confirmed many times. Your answer does not explain how is the concept of curvature of space more accurate / descriptive / useful theory than let's say the concept of gravitation force or field filed.

comment Does lunar module need the same amount of fuel for landing and take off?
nope, crash landing is not part of this question :)

comment Is there any limit on movement of space itself?
Every metaphor is imperfect simplification but that shouldn't prevent scientist from explaining concepts to layman. Strangely you don't like the rubber sheet metaphor - I used to think about objects in space as smarties in jello - if they are tunnelling through the jello they are moving. If the jello itself is warping bringing two objects closer or further then they were without them tunnelling through the jello then the space is moving while the objects are not moving. Or is this metaphor too far from reality?

Thanks for the undoing the hate. I am just a layman trying to understand interesting things.

So space can expand, warp, wave, bend, distort but not move. Got it. So is there a limit at which can space move but not move?

comment Mach's principle in empty universe, centripetal force and violation of Newton's laws of motion
I am not a physicist, I was merely reading Wikipedia when I got curious about the absolute rotation question and in there Mach's principle is presented as credible theory, certainly not outmoded like flat Earth. Does that mean that absolute rotation is accepted by mainstream physicists and Mach's principle is considered outmoded?

How is it different? Does the space not move when gravitation waves propagate through it?

Don't have a fireplace here nor a strong magnet. The answer is?

comment Are tidal power plants slowing down Earth's rotation?
@Mark I think they are. It's the same principle as a child on a swing, I think.

@Ted Thanks for the energy consumption calculation. Are you saying the earth will stop rotating one day completely? That will happen even without the power plants, right?
