Thanks bud. Reading now.

Sonic black holes are awesome.
Look them up.

How do you make one?

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.

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

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

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.

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.

user teach us about three body problems

Tell us your idea so we can steal it

give us your secrets

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

Lagrangian points.

Binary stars are actually pretty common.
