gravity waves' intensity decreases quite rapidly, so it approaches 0 much before universe's edge

QM, QFT, String Theory, M-theory and Chaos Theory

I don't believe half of what theoretical physics says, I think it's mostly nonsense, especially things like "time dilation" - if anything happens the molecules slow down, in my opinion you are changing the normal definition of time otherwise in a senseless way. There are signs of this sort of "heresy" starting to trickle into the highest authorities of the science, which is never a good sign for it being right. I just wish they would stop experimenting with things like the LHC because sooner or later a mistake or oversight will be made and it'll be curtains for everyone.

>especially things like "time dilation"
You say that but a big reason GPS works properly is because the clocks on the satellites correct for time dilation. It's definitely a thing.

it allows you to literally play with nature. You can make drugs, explosives, medicines, materials, etc...

Sounds like you've already judged it before learning anything about it. Typical brainlet.

because mathematicians don't have sweet labs and some people think physicists messing with lasers is outright boring.

My senior research was on organic chemistry; think about how frustrating it is to try to create something from a simpler chemical, then walking down to the NMR downstairs and BOOM you find out (by literally solving a puzzle of data) that you've successfully synthesized your product. As hard as it was, it was the most challenging and rewarding experience of my life.

heh, its pretty funny, psychology if you know how to use it can help you run the world.

He was successful because he was born rich in an influential family, people have used religion and all manner of other bullshit for the same means, but the rules of propaganda have changed dramatically since Bernays.

While I'm always happy to see the space exploration sector make positive moves, this is the literal definition of it's fucking nothing.

They're not made of coal, they're made of carbon.

>>8055216
You can see it like this:
[math]X = [/math] coal [math] \implies [/math] carbon [math]\in X [/math]
[math]X = [/math] diamond [math] \implies [/math] carbon [math]\in X [/math]
It's a one way implication. Containing carbon says nothing about what the material actually is.

Some cool shit so far, not sure if anything new.

-1 is also a lesser number then 0.

-0 and 0 are identical values

No. This whole post is the unfortunate abortion of your incredible boredom and exposure to popsci/scifi.

>r incredible boredom and exposure to popsci/scifi.
well at least you didnt call me on my ignorance, thank you

what i mean is, what is the closest to this we got? is there any project aiming for even something similar to this? im sure there must be research done about it, at least theoretical

I admire him for being curious and having enough of an interest to explore space, that said, I think it should be left to the Public Sector to do so. Private Sector is so far behind and lacks funds substantially.

>>8036026

what in the fuck are you even saying, the only time the public gets off their lazy social-wellfare asses and politicians taking funds for themselves is in times of war

That's not too difficult
Haven't taken math since high school, so I hope I didn't fuck anything up
Anyway
When we consider opposing tetragons, we see that they consist of two triangles. A right angled triangle that's the same for each segment, and two traingles with base b and height h1 and h2.

The surface area of a triangle is equal to 1/2 base*height. Their combined surface is as follows:
A = 1/2 b * h1 + 1/2 b * h2
A = 1/2 b (h1 + h2)
h1 + h2 is constant, so no matter where we move the centre point, the combined surface area of the triangles remains the same. The combined area of opposing tetragons is therefor also constant.
Opposing tetragons have a surface area of 16 + 32 = 48 cm2 , so A = 48 - 20

A = 28 cm2

Did I do a good job? I used to love geometry
