The Big Rip is an extreme scenario that supersedes that of a Big Freeze. Both of them are possible consequences of an ever expanding universe. While the Big Freeze can take place if the forces that are believed to govern the current rate of expansion are constant, the Big Rip will happen if the...

can somebody simply explain what is meant by NEGATIVE QUANTUM STATES , as given by dirac in his theory???i know its not as SIMPLE as i want it to be , but still I would like to know its significance in the most basic way!!
:approve:
actually our sir asked this question
and we explained all the things we could ( talking about carbocation rearrangement as well)
but he didnt look to be approved of what we had to say!!:rolleyes:
i mean whats the meaning of by time interval b/w their periodic approaches to each other over the min. distance??
uptill now i m doin this :
T = 2\pi1/2( r3 / GM)
so dT = 2 pi / root of GM * 3/2 r1/2 dr
so i hav found dT / T and hence dT.......
what to do next??
