Thanks for your responses. I was thinking that two objects were stationary with respect to each other but a long way apart. Me, the observer, did a fly by leaving the first behind as i approached the second at nearly c. An event was scheduled simultaneous on both objects. In this scenario i...

Am i right in thinking that relativistic simultaneity explanations tend not to mention the fact that one of the ‘simultaneous’ events may well be red shifted and the other blue shifted and by analysing wavelengths you could presumably work out whether the event was in reality simultanous or not.

I thought that your comment, "The movement of the air pocket is dominated by the flow of the water, which is being modified by the dolphins." inferred that there was a movement of water (underwater current) along the direction of the forward motion of the ring which was somehow counteracting the...

I also thought it may be dominated by a modified flow of water produced during the ring's creation but then if you look at this air vortex cannon video, about 1m 40 secs in, and look at the residual smoke there doesn't appear to be any modifying air flow associated with the smoke ring. I would...

If you look at this YouTube video you will see an example of a ring vortex made by a dolphin (there are quite a few other examples). The problem is I can't understand why the ring doesn't immediately float to the surface. Only when it breaks up do the bubbles rise. The ring appears to...

If you produced a focused beam from, say, a cassegrain transmitter which consisted of two waves merged but one inverted what would be the result. I presume there would be destructive interference. My question is, where does the energy go?

I think the actual variation in time is just dependent on what acceleration you subject the voyaging clock to and there will be no time variation once your clock is traveling at a constant speed, even if it traveled for years and years. I'm not sure what happens when you relatively subject it...

I think you need to forget about the ferric sand and think more about copper or aluminium 'sand'. Use gravity to drop it as normal and an induction arrangement to push it back up.

It's a nice idea. I think there are some hurdles ot overcome, the main one I can see is that as you suck the ferric sand with a magnet it will magnetise each particle so you will end up with them all sticking to each other. You may end up with a long thread of this ferric sand going up through...

Kev - re. your answer to Q2 what do you think would the be the visual effect if, for arguments sake, the black hole sphere is so large that for all intense and purpose the surface was flat (I'm assuming this would result in flat spacetime)?

Q1 if you were traveling at .99c and held a mirror at arms length orientated perpendicular to your direction of travel would you see a perfect reflection? Q2 if you were hovering within a few feet of the event horizon of a black hole and, as before, held a mirror at arms length...

Thanks for the link and your explanation. I thought that the 'lights would go out' for the reason that although the photon reaches you its wavelength has been red shifted to such an extent that it can no longer be considered a wave for practical 'viewing' purposes.

I think debating about the wire or the rope spanning galaxies is a bit of a red herring (not a criticism of your good postings just a general observation). As I read the original post the underlying meaning is "is it possible to go faster than light?". If it is true for distant galaxies it is...

So in practicality, we have two time variables, the significant one due to an illusion and the other real and due to relative acceleration (presumably this includes gravitational effects)? Could it be possible that if you accelerate time slows down but when you decelerate it speeds up...

Thanks for that. So I think we have established that in this new found symmetry the muons die at the same time. What happens when we reverse the process and accelerate the .99c muon back to the beginning again to join its twin in the laboratory? Do they still die at the same time?
