I have been studying along for these many years and there are so many questions in my mind... so many that i was going down on frustration. if i turn back and see all i have studied seems to be fake.. can someone help me in finding the answers. i have been working on this and made a blog out of this.. go through it and tell me if queries are correct.. or not.. foolishscience.blogspot.com experts of physics please help in this

I ' d like to help you with some of these. First of all Einstein considers that no mass can ever reach the speed of light, due to certain limitations (one of them is infinite mass). Light particles-photons do not have any mass. So there's no problem here. Bare in mind that in speeds like that mass tranforms into energy and vice verca so the everyday laws we know, do not apply. So don't get confused. Now, regarding the nature of gravity noone really knows why it behaves the way it does. Newton laws give only calculations and descriptions. They do not answer whys. It appears to have attractive nature. Scientists believe that there could be other universes where it is a repulsive force. Whether our universe will eventually become a black hole due to the attraction, it is an open matter. What is holding the moon around the earth, is the combination of gravity and original motion. think you have a rope and a ball attached at the end of it.if you spin around yourself holding the rope the ball will revolve around you. It will not collapse on you., although you hold it. If the moon didn't have this original speed, the gravity would pull it towards us, and it wouldn't care about us! Newton's laws are too simple to be used in subatomic systems. They would give false results

Thank you... but has it been proved that, photons do not have mass... and if you are true, then if a particle is at rest then it has to be acted upon by too many forces for the liking of the particle, it will be pulled by too many forces, wont the body get collapsed because of the influence of these forces; has anyone deduced those complex laws that suit sub atomic particles as such.

what is feel is what we consider as insignificant in the broader context hold the key for the small lapses in the theories when we ignore something we are making the biggest mistake knowingly aren't we

Consider that light is electromagnetic waves (energy, no mass). Depending on the situation and the way they interact with matter, we sometimes regard these waves as particles (that is small packages of electromgnetic waves -photons). These particles are not like the ones in the classical point of view were every particle has its own mass. Maybe this is the confusing part. Photons is a new idea. Under these circumstances, the theories about light have been prooved beyond any doubt. What we still need is to complement them or alter them in a way so that they describe everysingle physics phenomena. This is the hardest part, I believe. Also keep in mind that subatomic particles have such small masses that gravity forces are insignificant compared to the other forces (electromagnetic, nuclear etc).Quantum theory is used for atomic level and electro/chromodynamics for the subatomic level. There other theories as well. These are quite complex but extremely accurate.
