Thanks bud. Reading now.

Sonic black holes are awesome.
Look them up.

>>8499719
How do you make one?

>>8499727
You have a fluid moving faster than the speed of sound.
That way sound cannot escape it. Acoustic black holes (ABH) behave like real black holes in many ways. They even emit acoustic Hawking adiation.

>>8499732
Is it possible to create one in a wind tunnel? Seems really interesting.

>>8499738
Yes, in theory.
However, most of the time, they are created with lasers to heat the fluid.

>>8499740
That seems quite advanced, going to go look up the experimental setup, thanks.

Cool story bro

Soon you'll learn the true meaning of "close enough"

General three body problem.

That is all, astrokuks.

>>8499674
I want to create a slide rule/nomogram that can be used to compute orbits and intercepts around arbitrary 2 body problems.

The mass of the body will be known.

>>8501103
anon teach us about three body problems

>>8501252
Tell us your idea so we can steal it

>>8501252
give us your secrets

>>8501390
If you can't come up with the idea there's a fair chance you aren't able to figure out what's great about it anyway.

>Knows about the 3 body problem

Doesn't know about 2 and a half body problem, does not know about Laplace points, tubes or manifolds.
Good job >>8501252

Lagrangian points.

Binary stars are actually pretty common.
