E=mc2 ?

[wormholeman]

Dose E = MC2 equal infinite energy?

[ydoaPs]

no. why would it?

[Klaynos]

No:

 

E²=(m₀c²)²+(pc)²

 

There is limited mass, there is a max momentum therefore there is limited energy. Or something like that...

Urm not quite sure what I'm supposed to be saying, sleepy

[Aronathas]

Given infinite mass..

[ydoaPs]

Given infinite mass..

since matter and energy are different forms of the same thing, if you have infinite mass, you will have infinite energy. he didn't say anything about how much mass there is.

Dose E = MC2 equal infinite energy?

What numbers are you putting into it?

 

E and m are definite numbers and cannot be infinite unless the other is. The equation just states that energy and mass are related with the square of c as a factor.

[wormholeman]

E=energy (=comes from) M=mass at C=speed of light, squared=space.

 

Thats how I understand it.

[ydoaPs]

as stated before, you are missing the term with momentum.

[wormholeman]

why dose something that has a limited mass that can always remain at a speed

have limited energy?

[ydoaPs]

have limited energy?

what does speed have to do with anything? what is this speed relative to anyway?

 

limited mass = limited energy.

[danny8522003]

You mean why does an object travel at a constant speed without having to use up infinite energy?

[wormholeman]

or ya, why dose an object traveling at a constant speed use up any energy in space where there is no gravity?

[wormholeman]

what does speed have to do with anything? what is this speed relative to anyway?

if theres speed theres acceleration.

[ydoaPs]

F=ma. if F=0, then a=0. if a=0, v=constant, not negative. there has to be a force acting to slow an object down. fyi, there is gravity in space.

[ydoaPs]

if theres speed there acceleration.

not necesarily

[wormholeman]

dose not zero G equal no gravity? I thought in space there was zero G, no gravity.

[danny8522003]

When you say "in space", i take it you mean without a force acting against the pushing force?

 

If that's the case then it will only use the energy required to accelerate it to a constant velocity.

 

If you however speed it up fast enough (near c) in this Universe, it begins to get more massive because of the energy it contains from the original push and becomes harder and harder to accelerate further. That's why reaching c with a rest mass of >0 is impossible because an infinite amount of energy would be required.

[danny8522003]

dose not zero G equal no gravity? I thought in space there was zero G, no gravity.

Gravity exists everywhere within this Universe, zero G implies no curvature of space-time in the region.

[wormholeman]

ahh, ok I see. thanks

[danny8522003]

You're welcome, i hope that's cleared things up for you

[ydoaPs]

Creationist Lies! mass does not increase. mass is constant. momentum increases.

 

[math]\rho=\frac{h}{\lambda}[/math]

[math]d=\frac{d}{\gamma}[/math]

[math]\lambda=\frac{\lambda}{\gamma}[/math]

[math]\frac{h}{\lambda}=\frac{h{\gamma}}[/math]

[math]\rho={\rho}\gamma[/math]

[danny8522003]

I dont know how you managed to label me a creationist from that, i assure you i am not one.

 

Although you're right, mass doesn't change the objects momentum does. I dunno why i said mass, must be tired *yawns*.

the creationist bit was a joke

[danny8522003]

Glad to hear it.

[wormholeman]

Man! I wish things could be explained in simple terms always. It would make things much easyer...One question though what the hell is a creationist and why is it so bad?

I am a musician, I create, should I be offended? whats up?
