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.
So much...

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.
xxce2AAb@feddit.dk 1 day ago
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.

…safe maximum distance.
FTFY.

Easier to reach the stars with meth, not math.
technocrit@lemmy.dbzer0.com 21 hours ago
This requires lots of Physics. The math required is relatively minimal.

Eh, I remember just googling space stuff and absorbing info and that alone had enough dopamine. My world was so small before I got access to the internet, when I was a kid, I had a children’s book about science stuff, stars, but they barely had much info. Internet access was so magical. Unlimited information.
Lemminary@lemmy.world 1 day ago
I thought they meant movie stars and meant you could only get near them by becoming an engineer. I’m… not that smart at certain hours of the day.
captainlezbian@lemmy.world 21 hours ago
In my experience being an engineer keeps them further away

If you learn just a little bit of math you can realize that no one else is getting anywhere near them either.

Next year, Voyager I will have traveled 1 light day. It will also be over 49 years old at that time. Think about that for a moment. Almost 50 years to travel the time it takes light to travel in a single day. Our closest star is Proxima Centauri is 4.25 light years away. To reach Proxima Centauri, Voyager I would need to travel ~77,500 years. Voyager 1 is one of the fastest man-made objects in existence and it would take longer than the entire history of civilization to arrive.
Space is big.

And then Kerbal Space Program too had to go be a cash grab.
At least we have kitty space program
regdog@lemmy.world 1 day ago
KSP 2 was a cash grab, but KSP 1 is still a very good experience.
MBech@feddit.dk 20 hours ago
I love KSP 1,but it has gotten a bit stale with the years and playtime. I was 3 days from buying KSP2 when they shut down, lucky me.

Nah, just take a positional average and you’re pretty much in the middle of one!

Only if you weight by mass.

reading that as “stairs” was hella confusing for a solid minute.

Municipal development guy here.
You’d be amazed how many contractors and architects have issues with stair math.

I kept reading stairs but yeah both I guess

I interpreted this to mean that you need to learn a lot of math in order to have a career in astronomy. I don’t think OP thought it was possible to actually go to the star and math was the limiting factor.

That’s because math is fundamentally flawed.
Shhhhh. Don’t tell anyone, they get all upset about it.
Axioms@lemmy.dbzer0.com 1 day ago
Interesting! Could you elaborate on this? I’m intrigued to know the intrinsic flaws.
nednobbins@lemmy.zip 1 day ago
Kurt Gödel wrote a whole paper on it.
He used math to show that all statements, in any language, can be expressed as math statements. He then proved that it’s impossible to create any cpnsistent set of math statements that completely describes everything.
homesweethomeMrL@lemmy.world 1 day ago
It has to do with creating measuring devices out of what we can empirically derive, and building successive generations off of those. It’s fine for our local system but by the time you get intergalactic (or quantum) with it, flaws start to propagate themselves bigly.
I can’t reveal more at this time or Big Math will get suspicious.
gandalf_der_12te@discuss.tchncs.de 1 day ago
Just define “star” to include Earth, then you’re already very close to one!
Tollana1234567@lemmy.today 1 day ago
yes, astronomy, astrophysics, if yuo dont have knack in that field you wont get into it. physics, if you cant pass simple CComunity level physics classes(for scientists, not for life sciences), you wont pass upper division physics.
realitista@lemmus.org 1 day ago
The math isn’t really the main limiting factor to getting close to stars.
fascicle@leminal.space 1 day ago
Learning math is what makes you realize that
Tollana1234567@lemmy.today 1 day ago
but you need to have significant math skills to even understand physics in general.
solomonschuler@lemmy.zip 23 hours ago
No. physics is generalized to algebra, you don’t need to know a lot of math to learn physics. Having more math will allow you to do more complicated problems and understand concepts the way it was discovered, but it isn’t limited to those who know calculus.
technocrit@lemmy.dbzer0.com 21 hours ago
No. The math used in physics is just a tiny tiny part of wider math.
Chakravanti@monero.town 1 day ago
Yeah but a little bit of meth and you’ll surely figure it out.
