So does the "Spacetime fabric" have a capacity for inertia? It's stuff, isn't it? so if you applied enough inertia, you could warp it. And could this relate at all to zero friction, which, apparently impossible, could be approached with fluids of varying viscosity in a torus?

Some OC from our concerned TAs

Inertia is the ability of an object to resist a change in motion, such as angular velocity. Space and time are constituents of motion, so it certainly sounds plausible. Fluids of any viscosity will generate friction. On the other hand, fluids of zero viscosity (superfluids) are frictionless, and no torus required unless you want to create a special magnetic field around the object, or something. Why? Are you trying to build a warp drive?

Aww, y'know...

Just hypothesizing 'n whatnot.

>Yeah, if you kept applying energy to speed up a frictionless liquid to near light-speed, you might alter or break"spacetime fabric", because you've approached that sexy lightspeed.

Interesting. How would you speed it up?

Indeed, how to speed up a frictionless substance. Maybe with a polar magnetic field.

hmm... I think that would increase the current (not the flow of the fluid but the flow of electric charge). Maybe you can use that to your advantage though.

I'll bet they're using superconducting magnets to achieve it.

>Why are fusion reactors the size that they are?
It seems like we can't get enough energy to sustain the reaction. So, if we size it down, while pumping the same amount of energy, wouldn't that help?

2.
>Why can't it be sustained?
What about fusion reactors isn't working? Why isn't the reaction sustaining itself.

That's the reason inertial confinement fusion works. It took a 500,000,000,000,000 Watt laser pulse aimed at a fuel target the size of a water droplet, but for a brief flash of time, they finally got more energy out of it than was put in.

>What about fusion reactors isn't working? Why isn't the reaction sustaining itself.

The problem with ICF is that it takes a long time to build up a light pulse that only lasts for a fraction of a second, and the few milligrams of fuel is consumed in just as short a time. The problem with tokamaks and stellarators, is that the magnetic fields aren't strong enough. We already know that we can create uncontrolled fusion reactions (thermonuclear warheads), and the National Ignition Facility has demonstrated that it can be done in a controlled environment, without the need for a fission bomb to create enough compressive force. So now, how are we supposed to sustain these powerful forces... how...

the spacetime fabric would be the mesh that our universe is operating in, so the units would be flying past us at wichever rate the observed system is moving, in relation to the set position of the universe?

I have your zero viscosity fluid right here. Liquid helium will enter a superfluid phase when cooled to below 4.2K. You can increase the flow rate using pressure in a tube. Unfortunately, liquid helium will freeze but the pressure required is enormous, approximately 26 bar... SO I hypothesize your superfluid helium would freeze solid long before light speed due to inertia alone. All other frictionless fluids would have the same problem, but much much sooner.

Bingo.

I've been AFK on this thread for a couple months and came back to find some really cool responses. Thanks y'all.

If only there were a way to electromagnetically compress a DT vapor, while blasting it with a bunch of lasers or a particle beam.

which would allow control towards a constant level of fuel in the reactor...

Last bump I'll give this thread:
Where can I learn more about fusion? I want to help the world, but I don't know where to start learning. I want to learn as much as I can about this jazz without becoming Grant Green. Thinking what can I do to help the process along? Good sources of info. I figure one more mind working at the matter couldn't hurt.

Not on the subject of space-time fabric, but is there a principle limit to superfluidics? I had read that for certain materials, superfluid rotation is accompanied by vortices in the material. With sufficient size, would there be a competition between the vortex speeds and cooling due to expansion, etc? I imagine by definition a superfluid is in an "optimal" configuration of atoms, so what would happen if it was exposed to expansion forces which exceeded some property of the system?

Why not sound? Suspended into a combined magnetic webbing of some sort (mind you this is just me spitting shit) maybe use these magnets to potentially coax a "flow" of electrons from the "æther" or whatever you'd wanna call it. I honestly doubt what i'm thinking will output the however required to bend the universe but then again i'm just spittin shit
