Can the universe be created from nothing? It starts with initial conditions. In Einstein’s spacetime, the initial conditions of the universe...
I agree and I think this issue will not be resolved until we have a better understanding of the nature of space and time. More problematic is that...
The Big Bang Theory is based on Einstein’s general theory of relativity. In order to address the flatness and horizon problems in the original...
In its original form the density parameter Omega represented the ratio of the actual density of the universe to the critical density; i.e. the...
I agree with the article you cited that from an outside observer’s frame of reference the shape of the muon will be/is length contracted. Your other...
This is not directed to anyone in particular but it is in response to the preceding general discussion regarding distance contraction. I...
Thank you for that analysis of the issues we have been discussing. The most interesting commentary on this subject I have seen to date was by Dave...
Tach, I am not denying that accelerations can be handled within the confines of SR. I was merely trying to simplify the parameters of the...
In my initial post at the beginning of this thread I stated that a uniform acceleration could be handled within the framework of special relativity...
I am not an expert on SR and GR but I have researched this issue (especially the Twin Paradox) very carefully over the last ten years. When I am...
Thank you for that analogy and I think I understand your point. I know, however, that this is what we say. I just do not think that anyone...
Thank you for clarifying that for me. I guess gravitational time dilation could be the topic of its own thread.
This is a little off topic as well (and more to your point) but Dan Koks has an article on how clock rates only depend on velocity and are...
I assumed that Twin B would stop at Twin Earth and not return. I do realize there is Twin A’s time and Twin B’s time and they happen to be...
I do not even think those with PhD’s really understand the effect otherwise I would think they would be able to agree on one cogent explanation for...
I agree. There are four critical changes of velocity (in the standard Twin Effect)– one at the start of the journey, one at the destination, one at...
I am not sure you are necessarily incorrect about this. I think that in the standard Twin Effect, (not my Twin Earth scenario) unless Twin B turns...
The more I read the less I think we understand the Twin’s Effect.
If you look at the planes of simultaneity on a Minkowski Diagram it seems to imply that on the outward leg of the journey that Twin A’s clock is...
My point exactly. There is nothing paradoxical about the Twin’s Effect. My broader question was about what is really happening in Twin B’s inertial...
