e=mc2 squared

[zazzzoom]

e=mc2

 

well you got that far saying matter and energy are the same thing e=m

SO WHAT IS THAT STUFF matter and energy

[psicicle]

mattergy? thats what einstein called it

[ydoaPs]

if i remember correctly, hawking said something to the effect of particles being small pieces of spacetime. i'll look for it. also [math]E^2=(mc^2)^2+(pc)^2[/math]

mattergy? thats what einstein called it

but what is it!

Enery can take many different forms.

 

Kinetic, thermal, electrical, potential etc.

 

Enery could be describe as the ability to do work.

What does "p" stand for.

[Callipygous]

but what is it!

 

i have the answer!

 

after much consideration i have decided that the best, most informative, descriptive, and accurate answer is: STUFF.

[ydoaPs]

p stands for momentum.

[5614]

What does "p" stand for.

p = Momentum

 

[edit] applogies for double post, it weren't there when I loaded the page.

[The Thing]

What its suggesting is that energy & mass are interchangeable, and that mass is a concentrated form of energy.

If I am remembering correctly, Einstein was the first to put this idea forward. It was kind of his dream, he was never able to prove it though. It makes a lot of sense to me, if matter is dramatically curved (maybe curled) spacetime, then gravity is explained. I don't know, It is kinda farfetched.

[simple]

what is spacetime?

[ydoaPs]

space and time got married. then they had a baby. his name: spacetime.

[5614]

Space-time is a 4D universe, such as the one we live in... now other theories say that there are other dimensions, I do not know how this fits in... space-time is used to describe a 4D universe such as the one in the theory of relativity.

I quite like "it doesn't matter".

 

Mainly because it's a realllly good pun.

[Meir Achuz]

"The energy and mass of an object are closely related, but not equivalent. To within factors of $c$, the energy is the time-like component of the momentum four-vector, while the mass is the invariant length of the four-vector. The energy in the rest system equals $mc^2$, but while in motion, the energy varies with velocity".

Matter and energy is that which is in a three diamensional form moves and has gravity. the gravity is what seperates matter and energy from space space does not have gravity but it also is in a three diamensional form moves

[bascule]

SO WHAT IS THAT STUFF matter and energy

 

String theory says that both matter (hadrons/leptons) and energy (bosons) are made of little 1 dimensional vibrating strings
