Figure this out

Space-time geometry. Best way to understand that, I think, is in quantum gravitational fields. Gravity is fundamentally tied to space, as seen in general relativity. So in order to understand space, we must understand gravity. Quantum gravity is particularly interesting for this subject because at such a small scale, we can analyze the effects of gravity. Conversely we could relate this to where we stand in the universe, and ultimately attempt to describe spacetime geometry. The geometry of spacetime and its relation to gravity could uncover if it is possible to connect two distant points in space with an infinite gravitational well.

Idk why I'm typing all this out honestly, I have three degrees: astrophysics, physics, and mathematics.

My dick curves up, like a banana. At first I thought it was bad but it's actually quite advantages to hitting the g-spot

I have a Möbius dick. The length is immeasurable

Its the same thing.

>>9085973
If pressure is exerted on a fluid by the environment, the fluid is pressurized.

It's the same thing.

>>9086002
>>9086022

How is it the same thing?

Isn't the boiling point defined as when vapor pressure = external pressure?

This implies that external, or environmental pressure is constantly "pushing down" on the substance, trying to make it more liquid or more solid.

>>9085932
yes you can

Source: I took group theory and ring+module theory in 2nd year uni, and didn't take any number theory until 3rd year

So can you like just move time and space instead of trying to move faster then light?

>>9085941
Move it? In what substance does time and space reside through which it can be moved? Luminiferous Aether? Wibbly wobbly timey-wimey stuff?

>>9085954
Cant you just make alot of gravity some how and move spacetime, like if you was swimming through water.

I'll give you a bump with an animation of vortex math and torus geometry

I don't know what it is but it sounds like high-school-dropout tier brainlet pseudomath.

From what I understand it is a good model for electromagnetic fields and could be really useful for everything that is related to them.
Tesla supposedly played around with it a lot.

Just to be clear by what I meant by metal form

I think it's because the surface is so rouge as apposed to the solid metal which will usually have a very smooth surface. Rough surfaces tend to cause light to bounce off randomly and makes it look darker, whereas the smooth surface of cast aluminum will give a nice reflection.

Freshly ground aluminum will also have no oxide layer formed yet, so if you wait a little bit it might start to look more reflective

The surface of the "metal form" is pretty flat, or flat enough to reflect light like this.

I mean in terms of graduate education.

You can always kill yourself

Do you want a coffee mug made out of electrons?

Maybe I want to download 4 ply toilet paper, maybe I want to send a bucket of lithium to a buddy in Thailand, I just want to know if I can do it?

no
energy to matter conversion in such a scale you are asking for takes more energy than our sun could output in approximately one second. scientists, however, found a way to turn light in a photon-photon collider into matter on a subatomic level. it would take a shit ton of energy to do that, and you just create an electron and a positron

Exactly how i would expect anyone to do after reading wiki and some pop-sci. How did he manage to make an hour long video out of this little understanding is beyond me.

When you look at the universe and how fucking hard it is to do fusion, you realize it was always just a meme.

For example, the tiniest red dwarfs need a mass of about 75 Jupiters. And even for larger ones, their rate of fusion is so low that they have a lifespan of trillions of years. Pic is lifespan vs mass of Sun (Sun is 1000 Jupiters).

>>9085086
Yeah, but we do it in bombs, so it aint """"hard"""" to do fusion, it's hard to control it.

That's where

Yeah, I should qualify that by calling it self-sustaining fusion. That's the goal and it's hard. If the goal is any fusion at all, you can do it yourself with a homemade fusor. I just personally don't think fusion power will ever be anything but a meme.

Maybe another way to look at it.. given only a classical understanding of atoms, our Sun shouldn't even achieve fusion. It relies on pressures and temperatures that reduce atom separation enough to allow a very small amount of quantum tunneling to occur. That quantum tunneling is the elegant way. Solar core pressures simply can't happen on earth, so it leaves us just with brute forcing through temperature.
