Any physics PhD students or postgrads here?

My professor told us about an interesting and very famous thought exeperiment, but he didn't have the time to explain it in full detail.
I hope for you guys to know it and to explain it to me.

So here's the idea:
Imagine a sun made of ice and a sun made of lava. Both are moving at 0.999... c.
What would happen, if they collide?

Hey!
You!
Get fucked!

>> No.4877309

I'm going to answer you with a similar level of intelligence to that which was provided with the question:

What the fuck does "c" mean?

Assuming they collide at an angle of 180° and are both of mass m, they would fuse to form one perfectly immobile sun made out of water with mass 2m.

.9999c = 1 c so this is a bullshit thought experiment.

You're fucking retarded.

ohboyherewego
if a=b then ac=bc
0.999... = 1
(0.999...)c = 1c

>>4877343
That's wrong. It's funny how you cannot into babby maths.

>> No.4877405

>>4877378
0.999... = 1
get on with it.

orly? i didnt make it; i stole it
but several /sci/tards seemed to agree with it at the time.

what does happen, then?

How big is "a sun"

You'll need limits to calculate the result.

>> No.4877632

Moving at 0.999c? lolololol c isn't. speed limit faggot.

Atleast use a real speed limit next time your going to attempt to troll badly.

depends.
how cold is the ice?
