Moist Mayonnaise#5570: that isn't what infinite means. Pi is a finite number less than 4.
Cyber#3763: yeah thanks for correcting me
A-Milli👽#7774: I was gonna say something stupid just to be funny, but decided against it
A-Milli👽#7774: Pi is a finite number with infinite numbers after the decimal

Cyber#3763: lol, i am imagining the situation
Cyber#3763: math + alcohol dont mix
A-Milli👽#7774: I thought that said meth

Cyber#3763: yes we all are lmao
Capnarchie#7767: how bad would it be to use normal solar cells in space compared to space-based solar cells?
Deleted User#0000: they're the same cells

A-Milli👽#7774: I am just being sarcastic
A-Milli👽#7774: ignore me
Deleted User#0000: heh
Capnarchie#7767: but lets say you were making a low budget pico satellite, could you get away with using terrestial cells
Deleted User#0000: absolutely, yes.
Capnarchie#7767: good because i aint spending 1.2k on some small cells

Moist Mayonnaise#5570: The main reason being that typical solar cells are not radiation hard at all.
Deleted User#0000: SpaceX uses terrestrial cells
Deleted User#0000: covered in thin glass
Deleted User#0000: for rad hardening

Capnarchie#7767: more like a picosatellite
Deleted User#0000: is it a thing that is going into space from a pillbox launcher
Capnarchie#7767: i guess

A-Milli👽#7774: just break in and steal it
Deleted User#0000: I remember some service doing $5-10kish satellites
Deleted User#0000: but it was just a space on launch, _nothing_ added

Capnarchie#7767: would be nice
Deleted User#0000: but it won't survive more than a single digit orbit number
Deleted User#0000: because extreme temp swing
Capnarchie#7767: most likely
Capnarchie#7767: put a camera on the pcb to prove the flat earthers wrong
Capnarchie#7767: and theyll make a new bizarre theory

Deleted User#0000: successfully?
Deleted User#0000: as in, 5m off the ground?
Capnarchie#7767: like 700m
Capnarchie#7767: i dont know how much 1700feet is
Deleted User#0000: with a steam rocket?
Capnarchie#7767: yes
Deleted User#0000: heck
A-Milli👽#7774: yes,
A-Milli👽#7774: but, he got nowhere near high enough to see... |
A-Milli👽#7774: you can't physically see the curvature until about 35k feet
Capnarchie#7767: i think you can see the curvature from like 40km
Deleted User#0000: yeah
Capnarchie#7767: ~~close enough~~
A-Milli👽#7774: lol
Deleted User#0000: and weather balloons are like
Deleted User#0000: $200 each?
Deleted User#0000: + ... |
Capnarchie#7767: like weather balloons almost take you to space
Deleted User#0000: edge of space maybe
Capnarchie#7767: but how would you now get to orbit
Deleted User#0000: rockets.
Capnarchie#7767: well thats a good idea but something else than rockets
A-Milli👽#7774: You need a form of thrust
Deleted User#0000: noth... |
Capnarchie#7767: how far away from earth do you have to be to use current ion thrusters
Deleted User#0000: they're not powerful enough
Capnarchie#7767: is LEO good enough?

Moist Mayonnaise#5570: Carbon nanotubes are strong enough by a significant fraction, the problem is it's very hard to make long carbon nanotubes without any imperfections.

Deleted User#0000: or length @Moist Mayonnaise
A-Milli👽#7774: it would eliminate the issue with having it freestanding, and you could build it continuously
Deleted User#0000: or structure

Deleted User#0000: isn't it relativistically okay still
Deleted User#0000: I don't know much about the em drive theory
Capnarchie#7767: neither do i
Capnarchie#7767: i just know it doesnt like newton
A-Milli👽#7774: as far as I know it was supposed to be launched into a decaying orbit and turned on to see if it outlast... |
Deleted User#0000: too much to account for when the em drive is basically a space fart
Capnarchie#7767: interest is financial stuff and intrest is actually the correct term **right**?
Deleted User#0000: interesting
Moist Mayonnaise#5570: There's a huge amount of things that actual physicists would much rather test in s... |
Moist Mayonnaise#5570: That isn't pessimism in the slightest, it's realism.
Capnarchie#7767: tell musk that this will get stuff to mars and boom you might get a sponsorship even
Salt#1137: EM drive is trash
Moist Mayonnaise#5570: There's no reason to believe I could manage to throw something to the moon either, that is... |
Capnarchie#7767: although technically the general relativity or special relativity still had maxwell equations for the wormhole mumbo jumbo and ftl
Capnarchie#7767: **if*
Salt#1137: GR doesn't have maxwell equations
Salt#1137: That's electromagnetics

Deleted User#0000: well, harder math
Capnarchie#7767: well unless you have a disability towards math you can even if youre dumb
Deleted User#0000: I can design electronics but if you give me a calculus book I will stare at it as if it's an alien language
Capnarchie#7767:... |
Capnarchie#7767: because i havent studied it yet
Capnarchie#7767: and i probably wont until i actually go study maths in college
