It's just some basic trig. But honestly, I would need to see a source on that. Yeah, this is the sci fi forum.

TL;DR at bottomIt's a somewhat accepted convention that in realistic scifi space fighters should be impossible to use effectively. In general they are regarded as being easy targets that, at interstellar ranges would be unable to survive in a battlefield that employs current plausible scifi...

Yes. It's just like shining a flashlight into a fire.

What would you call the "time" before space-time?

Great, so when do we get our Heisenberg compensators?

Let's just assume the wire is super conducting for the sake of simplicity.

I see how that would work in that particular example, but since the light bulbs in this case are in a circle, I wouldn't expect all photons from the lightbulbs to arrive at the same time as the electrical wave. Photons from a light bulb across the diameter of the circle from the power source...

I have a bit of a puzzle I'm trying to answer. A K2 civ decides to celebrate Christmas, so they build a circuit of trillions of Christmas lights 1 LY in circumference. When they flip the on switch, what happens? Do the lights come turn on one after the other in response to the electrical...

Ouch that's pretty harsh. I've read quite a few theories on the matter of dark energy and gravity. Can't say I've seen anyone provide the definitive understanding of these particular phenomena yet.

I'm not neglecting that. Any change in wire A's field propagate at the speed of light. So if wire A's field is shut off the change in the field would take time to reach wire B. So there would be a period of time where the field produced by wire A is present in space occupied by wire B's, but no...

That's why I'm asking questions and not writing papers on astrology. I'm not asking if the galaxy expands. My question is whether or not the accelerated expansion of space, due to dark energy, and the contraction of space, due to gravity around a star, could affect the perceived velocity of a...

But from what I've read about dark energy, it's present in all space, which would include within galaxies. And it does cause space to expand, just not a rate that exceeds the force of gravity. I do have a laymans understanding of the Alcubierre metric, but it seems that the expansion of space is...

So I have a question regarding the Alcubierre metric and the phenomena of stars on outer edges of galaxies moving at higher velocities than their orbital calculations state they should. When taking the accelerating expansion of space into account due to dark energy, could a sub-luminal...

Which just means more binding. He needs to wrap it around the spool more times. The more the rope "grips" the spool, the more the spool "grips" the rope. He also might need a second spool since he's trying to use two ropes. Can't say what rope he needs since he hasn't mentioned what's the weight...

Have you tried using more rope to make a full binding around the spool?
