look Beprepared mass of a body is relativistic in einstein theory and in SR you can find a equation on how mass increases with velocity of a body. what einstein said about acceleration is that all laws of physics are same in accelerated reference frame. it is the first postulate of SR. the...

If not the red shift then perhaps microwave background radiation which is the solid evidence of the Big Bang (or something like that) will show some light on your question of accelerating universe. To me it seems that the expanding of universe is true in the highlight of redshift and the idea...

If a man is traveling in a spaceship and it is moving with the speed of relative to c, then several changes will occur. For the guy in the ship, the space is appear to be bending towards it or in other words you can say that the distance is shortening for him. this will happen because of the...

well I think 'isolated in space' is means that body of certain mass is alone to be observe or in other words it is alone. You can imagine that it is easy to observe the effect when it is only one who shows some deformation in light's straight line path. prakash0

you understand it wrongly. Listen Tantalos pulse of light is seems to traveling in diagonal way to you but it did bouncing up and down all the time and didn't goes against the Maxwell law. it is relativity you are talking and in it such phenomena occurs and this point is confirmed by a Harward...

now i can see what troubles you. I didn't understand first what do want from slowing of light clock. Now see, if a man in rocket is traveling at 80-90% of c and he has a light clock in rocket in which a pulse of light is bouncing up and down. for the man in rocket pulse of light is bouncing...

first of all i say interesting idea you got there Hrash0. first you must understand that photon rate of flowing of time is same for photon and it will seems to slow for the man who (try to ) obs. it and don't cosidered space alone and time alone in special relativity. if you do this you will...

As far as we can tell, it does appear to be true that the speed of light is the same for all observers. This fact was predicted by Maxwell when he united the electric and magnetic forces into one. From his equations it was possible to calculate that the resulting electromagnetic field travels at...

well now as you mentioned it I am also looking for such thing and hope to reply soon with a good argument.

well it's not make sense at all. in past matter and antimatter were created from pure energy and the expansion rate of universe is too much for annihilation to occur and matter is taken away from antimatter. This point is also appreciated by Stephen Hawking. But the real question is how we...

you must see this like sun is also relative to you with 1000 mph. your speed then 0 mph is also correct if you consider sun and u both moving around the galaxy with same speed and your speed is zero relative to sun. I'm sorry to say but actually there is no new science in this. you should...

Can anyone tell me how to calculate the energy difference of a "proton and a electron independent and without influence of any forces" from those "who combines to form a hydrogen atom"?

i also agree with Andrew Mason. he is a good champ.

It is true Newton's third law is made for classical physics like Bohr's theory etc. but as bohr's theory is evolve or redifined by quantum physics you can also state third law in qm's language. what you have to do is to take account of changes occur at atomic level in a body when it is in...

what you're saying isn't false but not fully true. That point contains infinite amount of energy and the density of that point is also infinite. this is the answer of your problem with the view of classical physics or by relativity which predict singularities. However in quantum physics no...
