Yeah, that thought crossed my mind too, but the article I got it from used that term, and it's more easily visualized than x cubic metres....

IIRC one of the bases of thermodynamic physic is to accept light as a wave AND matter.

You mean like anti-light? If you accept light as matter then you must also accept the principle of anti-light. So I guess that i would have to have the same effect as all matter anti-matter effect: a whole lot of energy disload.

If on the other hand ligh tis just a wave and it encounters a wave in the other direction matching speed and frequency then they should either double or cancell eachother out if they are on the same phase or opposite phase.

I, actually, think this is a rather legitamate descussion. I just feel that in even the most logical discussion a little humor is needed. Science is a srious topic but that doesn't mean it has to be taken totally seriously, just look at one of the best, most informative science shows out there: Bill Nye; The Science Guy. He treats science with humor and it works. I bet he would've liked the joke. I had just hoped someone would get it as a joke... Oh, well...

RE: Another odd question...

And another one:D
If u sitt in a spaceship and u goes ar the speed of light.
Would u see your self in a mirror?
This problem made Einstein ponder alot and he said it himself he got into large psykological problems because of that.
He had to force himself to think that u did.
BUT can u see yourself in a mirror if u and the morror goes at the speed of light?:)

Also can u see a the front of a mirror?
This one has been diskused alot in my class.
 
RE: Another odd question...

If you are sitting in a train that is going, say, 25 miles an hour, and your top speed walking is about 15 miles/hour, walk up to the guy a couple of rows ahead ?

I think you can (see yourself in the mirror, I mean). Velocity is alway relative to something.

I dunno.. actually I don't think they do.. I think most of the match head is just sulfur..

Doubt it. If that were true, matches (I'm talking about your regular every-day carton matches) wouldn't cost virtually nothing.

or do you just see the light that is sent in return from yourself.
 
RE: Another odd question...

Well, first it bounces off you, then the mirror, and then it hits your eyes.
The real answer to this question is that only the spaceship travels at light speed. You are sitting motionless in it. So, if you move forward, you actually break the light-speed limit. Well, you don't, and the spaceship doesn't too, but to another motionless object, you are going faster than the light speed. This question isn't really much different from the "two particles at 75% light speed"-question.

That gives me a neat idea. If you put a circle-shaped tube between, say, the earth and anotther point in space (a distant solar system, perhaps, and you spun that circle at light speed, while inside that tube you put a small, astronaut-containing capsule, and have that capsule push itself off the tube (and cearting forward movement, sorry for my bad english), it would travel at speeds above light speed. Neat huh ? Now find a something to construct the tube......

Yeah, but it isn't like cathedrals are as common as your average McDonalds or anything.. when I think of cathedral, I thinking of the Notre Dame cathedral.. and I don't know how "average" that would be..

Yeah, but matter compresses and becomes more massive as it approaches the speed of light. When you finally *do* reach it, you become infinitely thin and infinitely massive. It'd be pretty hard to walk forward like that..

But my question: Does that only happen from the reference point of an observer? *Can* you walk forward in your fast-as-light space ship in *your* reference point?

RE: Another odd question...

Ok , but if the "vehicule" that you sit in motionless would instantetly stop, you`d need a pretty good Air bag on this vehicule cause you're are travelling with it at the speed of light.
I believe that the result of such a change of velocity would result in you becoming a "Coyote-running-after-the-road-runner-and-then-hitting-the-metal-plate-and-making-an-imprint-of-himself-about-three-feet-deep" and then liquify from the impact.

isn`t cathedrals a unit of mesure in your country?
It`s part of the system they use in Englang along with "One pound is 8 stone, there goes 12 stone in one hundredweight, so one hundredweight is effectively two thirds of a sixtieth of a pound. It's that simple and convenient!" :P

No it's not. It's part of a system that was developed for people who have trouble estimating measurements.
Like : four matchboxes are one fist,
four fists are one ball,
four balls are a cardbord box,
four cardboard boxes are one chest
four chests are one compact car
four compact cars our one truck
four trucks are one house
four houses are one cathedral
etc.

RE: Another odd question...

Well, the answer I thinks is with Newton (I could be mistaken). I came across some scientific article about Newton's laws, and the said something along the line of "The laws of newton apply only to system of axis (plural of axe, as in x-axe and y-axe)"
Bah, this doesn't make sense. I'll have to dig up that magazine before I can answer this question properly, and unfortunately, that magazine is at my school.
