I had a doubt regarding the propagation of de Broglie waves. How do we know the speed of propagation of these waves and also do there characteristics( speed and amplitude and frequency) depend on the source particle ( or they depend only on the motion(momentum) of the source and no whatsoever...

But then what about mass being indeterminate?

Well if we consider that "something" can be really "mass less" , would it be correct to consider it to move at the speed of light? If yes, then I have a little doubt. Let's say it moves at the speed of light , then if we apply the mass equation (mass=[(rest mass)/squared root(1-(v^2)/(c^2))] ...

Thank you for your explanation. But still the concept of entropy doesn't satisfy me. It would be great if you could suggest me some resources to understand the same.

I just wanted to clear a little doubt of mine. The second law of thermodynamics says that every physical system wants its entropy to be increased, the universe being a physical system should be doing the same. But , then why would two bodies want to attract each other (gravitation) even though...
