zazzzoom Posted March 23, 2005 Share Posted March 23, 2005 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 Link to comment Share on other sites More sharing options...
psicicle Posted March 23, 2005 Share Posted March 23, 2005 mattergy? thats what einstein called it Link to comment Share on other sites More sharing options...
ydoaPs Posted March 23, 2005 Share Posted March 23, 2005 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] Link to comment Share on other sites More sharing options...
zazzzoom Posted March 23, 2005 Author Share Posted March 23, 2005 mattergy? thats what einstein called it but what is it! Link to comment Share on other sites More sharing options...
5614 Posted March 23, 2005 Share Posted March 23, 2005 Enery can take many different forms. Kinetic, thermal, electrical, potential etc. Enery could be describe as the ability to do work. Link to comment Share on other sites More sharing options...
ecoli Posted March 23, 2005 Share Posted March 23, 2005 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] What does "p" stand for.

Callipygous Posted March 23, 2005 Share Posted March 23, 2005 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. Link to comment Share on other sites More sharing options...
ydoaPs Posted March 23, 2005 Share Posted March 23, 2005 p stands for momentum. Link to comment Share on other sites More sharing options...
5614 Posted March 23, 2005 Share Posted March 23, 2005 What does "p" stand for. p = Momentum [edit] applogies for double post, it weren't there when I loaded the page. Link to comment Share on other sites More sharing options...
The Thing Posted March 23, 2005 Share Posted March 23, 2005 What its suggesting is that energy & mass are interchangeable, and that mass is a concentrated form of energy. Link to comment Share on other sites More sharing options...
Deified Posted March 24, 2005 Share Posted March 24, 2005 if i remember correctly, hawking said something to the effect of particles being small pieces of spacetime. 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 Posted March 24, 2005 Share Posted March 24, 2005 what is spacetime? Link to comment Share on other sites More sharing options...
ydoaPs Posted March 24, 2005 Share Posted March 24, 2005 space and time got married. then they had a baby. his name: spacetime. Link to comment Share on other sites More sharing options...
5614 Posted March 24, 2005 Share Posted March 24, 2005 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.

Sayonara Posted March 25, 2005 Share Posted March 25, 2005 i have the answer! after much consideration i have decided that the best' date=' most informative, descriptive, and accurate answer is: STUFF.[/quote'] I quite like "it doesn't matter". Mainly because it's a realllly good pun. Link to comment Share on other sites More sharing options...
Meir Achuz Posted March 31, 2005 Share Posted March 31, 2005 "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". Link to comment Share on other sites More sharing options...
eeemmm Posted April 30, 2005 Share Posted April 30, 2005 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 Link to comment Share on other sites More sharing options...
bascule Posted April 30, 2005 Share Posted April 30, 2005 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 Link to comment Share on other sites More sharing options...
