Welcome to c/science_memes @ Mander.xyz!
A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

That or the right job application and a lot of propellant and oxidizer - but seriously, don't do that. It didn't end well for Icarus. Gravitationally-driven open-core fusion reactors are best admired from a safe minimum distance.
You can only realistically get close to one of them that way.
You are better off studying plasma containment fusion. And that's a fuckton of math.
Oh no. You can get close to any star of your choosing with only minuscule amounts of reaction mass if you start out in vacuum away from significant gravity wells - eventually. Granted, the star in question may or may not have gone supernova or collapsed into a black hole by the time you arrive, but I doubt that'll make a lot of difference to the person doing it at that point.
With that said, I'm not about to discourage anybody from taking an interest in fusion of the up-close-and-personal-kind. And if people aren't into the math of Magnetohydrodynamics? Well, first off, sucks to be them, but second: Then donate to the cause to pay those who are. Fusion is fucking awesome, and we desperately need it.
Even fusion constrains you to the limits of the rocket equation. Laser sails on the other hand, could let you put the bulk of your propulsion system in orbit of the sun or something where you don't have to carry it with you.
FTFY.
Fair.
