That's the trouble with semantics, Bill. What one person hears might not be what the other one thought he said. I think that you have been on the receiving end of just that in this thread.
Anyway, as I understand it, Penrose is proposing that the Universe does NOT expand forever but just...
This is a fascinating thread but I still think that it is getting bogged down in Semantics.
First of all there are large numbers supporting both the ever expanding universe and the big crunch theories although the former are currently in the ascendancy. Bill seems to be in the latter camp and...
Thank you for that. From my limited reading I can see that the evidence for the current accelerated expansion is overwhelming but won't we have to wait until projects such as SDDS are completed (if that is even possible) before we can say for sure whether this will continue forever or at some...
Seems to me that both sides are stating their preferred view as FACT and ridiculing any contra view rather than referring to supporting evidence or logical argument.
Personally I would prefer to be directed to supporting articles and evidence to help me consider both sides of the argument.
It would indeed be extremely unlikely that the Black Holes would combine if the universe expanded forever rather than reaching a contraction stage but I thought that the jury was still out on that?
Am I correct in saying that in theory Time, Matter and presumably Energy are compressed to a singularity at the centre of a black hole?
If that is so then wouldn't they be "transported" back to the state and position they were in at the very beginning of time. In other words the instant of...
Well the speed of light is also a mathematically proven fact but the OPERA experiment casts doubts on that.
Plus if the experiments prove that actions on one of a tangled pair affects the other then they must have observed the effect on the other. In other words they have passed on...
Thank you all. So now all we need is faster than light communications and we have a viable colony. Anyone invented a communication device using Quantum Entanglement yet?
Thank you for the replies. One further question please.
Does this mean that when our traveller disembarked at their destination, time for them would pass at the same rate as the observer on Earth? Let's not worry about stars moving apart or the universe expanding for now. Their twin would be...
Um not saying it is possible but what I am trying to get my head around is the old conundrum of time "passing" slower for an astronaut traveling close to light speed relative to an observer so that when they returned after say ten years their twin brother on Earth would have aged 500 years or...
If a spacecraft were traveling at the speed of light (OK, forget the difficulties for now) relative to an observer on Earth then would it appear to an occupant on that ship that they had traveled instantly from one point to another?
