ZOMBIE FORUMS

Or Aussies (Homo Aussiens) from Humans (Homo Sapeins), Or Texans (Who're you callin' Homo? shithead!)

*confused* I used to live in Texas...and I think you missed something in that simulated reaction, like the discharge of a rifle. Such an...interesting place to live.

Heh heh, yeah, where do you live now?

Illinois, land of corn and snow.

I'm from Amarillo originally, then I moved to Lubbock for school, and I have seen no snow. It sucks ass.

I'll see what I can do to try to say something on this and get you those headaches. Bewae that it is 1am and I have not consumed any caffeine recently. I probably shouldn't discuss physics in the state I am, but here goes:

The question of what speed energy travels at is rather tricky. The thing is, we're not sure what energy actually is. It's what makes things happen, "the go of things" I believe some have termed it. The food you eat "contains" chemical energy that your body can store and use (transform, actually. Energy cannot be created or disappear, only be transformed into another kind of energy) to, for instance, move your body. A piece of wood "contains" chemical energy that can be transformed into thermal (is that the word?) energy (usually known as heat) through burning it. As such, if you carry a piece of wood the energy "contained" in it can be said to travel at the speed you're moving.

However, the particles that "transmit" energy such as photons and gravitons (have they proved the existence of gravitons yet? We had something about it in physics last year, but I can't quite remember it), travel at the speed of light. The speed of light in vacuum is usually regarded as a constant, and the highest speed attainable by anything

(Note also that Einstein's famous equation E=mc^2 implies that energy equals mass, just multiplied with a constant, the speed of light.)

Edit: Doh, quoted and forgot to put in my own text before presing submit. Shows how much to trust my thoughts at this moment.

i member that stuff. think most of it was covered in Chemistry.
Energy isn't created or destroy but is transmuted.
i think that was proven wrong. Detonating an nuclear bomb actually creates energy, i think. i not remember so well.
not to cause any damage to other's ways of thinking, but i think Einstein's E=mc² was a little premature. it makes any space travel impratical as it will take toooo long to get anywhere. it could be totally right if someone discovers how to "warp" (erk, need more info on what warp is before i can say that with confidence) or enter "hyperspace" or any of the other sci-fi created modes of space travel.

if meji weighs about 20 lb, ellis about 4 lb: 124 lb = m
speed of light: about 186,000 mph = c

124*186,000²= 4,289,904,000,000 units of E.
that's a big number. wonder if it's right.

Few problems there, firstly, I think you meant to say Meji ways 120 lbs, not 20.

Secondly, this needs to be metric for it to work properly

Lets say Meji is 45 kg and Ellis is 2 (I dunno, I suck at estimating in metric. I just do)

E=mc^2
E=47X(3X10^8)^2
E=4.23X10^18 Joules
E=423000 terrajoules

I have heard the theory advance that there is no fundamental difference between matter and energy, forms of energy and forms of matter are really all forms of the same thing. It makes a sort of sense to me.

dont forget to take into account magic...

Magic:
the easy to understand variable about everything.
It just works! Don't question it!

EDIT for my previous post: oops about Meji's weight. i was originally doing it in pounds and then thought i should do it in metric but couldn't think of the proper energy unit and switched it back to pounds. BTW, their combined weight is more like 54 kilos.

Thanks themadthinker! glad someone could do it properly.

Einsteins theorys stated that any object that approaches the speed of of light, would end up with an infinite mass. He said nothing about things already traveling at the speed of light. So presumably, long distance space travel could be done, but speed would have to start at the speed of light, not below it and approach it.

Mmm...I've always been one of those people that believed that the speed of light is nowhere near constant, just that some dolts assumed it was since they really only measured it through our own atmosphere and now everyone treats it as one. *shrug*

If it was a constant, and anything actually did approach the speed of light, I don't think it would possess infinite mass, but would be in essence divided by zero. This could go either way, or no way..could be considered to be infinite, or infinitely negative, or even verging on a new dimension theory. Do what you will with my idle speculation.

Another cool thing is that traveling faster than the speed of light is possible. You just can never go at exactly the speed of light. Of course the faster you go, the more you mass you gain and if you should hit anything...

If I remember correctly, (and I may be horribly wrong), it was proven that the speed of light is not constant. Doesn't it slow down through water? Or am I thinking of something completely different, and connecting random synapses?

You are correct Ezelek. To the best of my knowledge, the speed of light varies from one substance to another. Now as for the formula E=mc^2, c is the speed of light in a vacuum, where it is pretty much constant.

The constant part is indeed the speed of light in a vacuum.

one of the more filled out equations which takes into account situations slightly more complex than others is:

E^2 = M^2C^4 + P^2C^2

Where P is something like momentum, but i cant recall right now.

The speed of light is relative though. Suppose you've got an imaginary object traveling almost the speed of light away from an imaginary point in space, that happens to be traveling as the speed of light away from you; that is to say, the object is moving almot 2x the speed of light away from you and the point is traveling at almost 1x the speed of light from you.
Relative to the point, nobody's going over the speed of light, but relative to the object, you'd be going almost 2x the speed of light.
How does one know what is or isn't alrady moving relative to space itself?

NO, thats the point. youre not moveing at 2X speed of light, you look like you're moving at the speed of light. thats why its fucked up. thats the whole "holy shit" aspect of it...

This is making my head hurt...
