hey.... how can this affect photons???? i mean light contains nothing but phtons... how can this dark matter attract photons ?????

thanks buddy ))

Hey guys, Once my teacher was taking class on thermodynamics.. and we came to know about kelvin's experiment. he said that if the body is cooled upto -273.15 deg. C or 0 kelvin, the pressure exerted by the body will be 0. I have a doubt. If p=o, force/area = 0, mass * g / a = o. a cannot be infinity.... so there are two cases.. either of mass or acceleration due to gravity is 0 case i.) g=0 that means temp. has efect on gravity... i.e. if temp. =0 , g=0. as far as iknow gravity and temp. are independent. case ii.) m=0 if mass = o, enormous energy will be liberated. And if mass = 0, that means the body no more exists. so how can superconductors exist in 0 deg. kelvin??? and even all tha bodies irrespective of shape and mass should loose all their mass at 0 deg. kelvin which is again practically nt possible... so please hepl me out.. just tell me how the pressure exerted by the body becomes zero.

I have been assigned to do a science project for my school... can you guys give me some idea abt the project.... Thank you...

I never said that the rotation effects the path of light. I just said that till the light of sun reaches the earths ground, i.e. eight mins, we will be moved 2 degrees.So the position of the sun what we see will be changed relative to our motion.

We see the sun's light after approx. 8 mins ( we will take it 8 mins and neglect that 32 secs.). That means that we see the sun as what it was 8 mins before. But earth rotates along its axis. It rotates 2 degrees in 8 mins. Therefore what we see from the earth is not the actuall position of the sun. what we see the sunfrom earth should be its position 2 degrees west. Ain't I right or am I just Confused??????

Music is sound. Sounds are waves. Wave is science and thus music is science.
