this is prob gonna sound really dumb... (1 Viewer)

umm in multiple choice.

wat was the answer for the two spaceships relatative speeds, and the light ??

 

[Afurotsu]

Light is always the same speed. The speed of light was the same for both ships.

 

[bevstarrunner]

A... light ALWAYS travels/arrives/does whatever at speed c

 

[senso]

but with that? isn't that only from einsteins theory?
I thought it hadn't been definately proved yet

 

[Jezzabelle]

Light is always the same speed. The speed of light was the same for both ships.

woooooooooohooooooooo i hope your right cos thats wat i thought too. i HATE multiple choice where one of the option is "not enough info" its sooo annoying!!

 

[mr EaZy]

speed of light is speed of light

einsteins theory is the theory we all use when dealing with light!

 

[ahvan]

but with that? isn't that only from einsteins theory?
I thought it hadn't been definately proved yet

wow didn't even think about that..
yeah it hasn't been proven, so in a way you could say 'not enough info', yeah?
but I take it that bos want us to tell them mr einsteins' theory states that c is always the same...

 

[peeasoup]

Wasnt it D. Because, say alpha spaceship is travelling at 0.9 the speed of light. An observer on that spaceship will view the light as moving very slow, catching up to the spaceship.
?!?!?!?!?!?!?!?!?!

 

[Plebeian]

If you lived in the 19th century, that's exactly what you'd think. But half the point of relativity is that the speed of light is constant for all observers.

 

[peeasoup]

What are you an idiot. The observer in the fucking rocket sees the light catching up to him, you stupid fuck. If alpha was moving at the speed of light, then the light wouldnt move, so alhpa would see nothing...
Think before you type shit like that, you dumb arse, and grow a brain...

 

[Brad]

ummm no. Einsteins theroy says that the speed of light is constant for all frames of reference.... If we are saying it hasnt been proved then we could do that for many other things too....

 

[artfaggette]

I move that BOS only allows people who have a clue to post replies. For the question above, it's impossible for rocket alpha to move at the speed of light, therefore it's moving slower than light, therefore it will SEE the light and so Einstein's theory tells us that the observer in Alpha will measure the speed of that light as C.
And special relativity HAS been proved you dickheads. Did anyone here actually DO the HSC physics course? I didn't and I know this much FFS!

 

[Afurotsu]

Yeah, time changes so that the speed of light relative to you is always constant.

Unless you're trying to prove Einstein wrong, then you're wrong Peeasoup. Bad luck.

 

[pussy_cat]

Hey peesoup you shouldnt get all angry and insulting ppl until u know ur right cuz now u just look like a total dick that thinks they know everything but dont. lol, lighten up a bit will ya, its over now...

Oh and by the way it was A cuz the speed of light is the same in all frames of reference

 

[sub]

it was A? YES!! another one right for me...

it was bloody obvious tho

 

[peeasoup]

Why do i bother even argueing with you morons.

 

[Afurotsu]

"Morons"... I guess you'll have a good time when you get back your mark for Physics then, eh?

 

[peeasoup]

Huh. Wasup ?

 

[pussy_cat]

your real nice hey, and why are u being a jerk when ur obviously wrong???? it just doesnt work like that!! lol

 

[SeDaTeD]

Peeasoup, have you actually done the HSC physics course? There's an entire section dedicated to relativity.
