Ok so, two situations: 1] Both the boat and the submarine is at rest 2] The boat is moving in the -x direction and the submarine is moving in the +x direction. Wouldn't the speed of sound be different in the two cases?

I agree with TCS and Austin on one point. I think it could very well be a medium which we 'perceive' as space. It doesn't have to have a flow as was the basis of the M-M experiment. And matter could be the perceivable 'complement' of space.

I know what you mean. I understand the concept of higher dimensions and other realms of our universe (beyond our perception), but honestly, seems I need to study deeper to get it clear. Well light has to originate somewhere, what if I let that 'somewhere' be the reference object (say, the...

@bcrowell But this again is experimental right? And I'm sorry but my knowledge in this field is yet shallow, so you lost me on the universal simultaneity thingy. Also, what I inferred from you post is that a particle cannot be accelerated to light speed with such high a force due to some...

But this is again experimentally shown isn't it? Is there any available derivation?

So this still leaves the reason behind the invariance of c, a mystery. I guess it's better to leave it that way.. for now. Another question: Is there any solid experimental evidence to prove that mass increases with velocity or the phenomenon of time dilation?

I understand the Michelson–Morley experiment and its result; but what I don't know yet is the REASON. Example: A torch in free space is moving at a velocity [v] w.r.t me. Considering the material nature of light, shouldn't the speed of photons emitted from the torch be [v+c] w.r.t ME? According...

"Torque produces a change in angular momentum of the top" The last part was a bit uncelar. Does rotation always have a 'revolution' effect or vice versa? I mean does a rotating body tend to revolve around some central point? If yes, then how? If no, then how does the top start its precession?
