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...
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?
