What if I am walking forward at 2 mph on the train that is moving forward at 60 mph? Would my velocity relative to a stationary outside observer be 62 mph or would it be less? Please explain.

Can you elaborate? From the inner-most disc I would only be moving 500 mph. But outside the discs, the inner-most disc could appear as though it is moving at the speed of light. Are you saying simply that from outside the discs the inner-most disc cannot appear to be going faster than light...

If I have an series of discs within each other (imagine a bunch of o's within each other, the outer one the largest, the inner-most one the smallest, and I am not limited in quantity), each spinning in the same direction and each spinning from a motion source in the disc just outside it so that...

True.. but that's what makes arguing about it so much fun, right?

Putting aside the multi-verse theory and focusing on a single universe for this issue (or maybe the way I am thinking implies multiple universes, but from the standpoint of time)... I guess my question really comes down to what it means to be able to travel back in time. If I go into the past...

But I am constantly moving forward even as I go back in time, right? So isn't possible that the ripple simply never catches me? Using a clock ticking off the seconds... if I am at second 30 when I go back to second 1 and kill my grandfather, I am still moving ahead on the clock as I...

Just an amateur (and hardly even that)... so take it easy on me... but I have some questions about the Grandfather Paradox. Assuming time travel to your past were otherwise possible, doesn't that imply that each moment in time is its own unique physical state existing simultaneously...
