Re: Stopping time

Yes, a watched quantum pot never boils. If we have a helium-6 atom in quantum state and we observe it frequently, it should not decay. This is so because when we observe it, we keep reseting it's state. No high energies, or any energy transfer, is involved, just the observation. Nonsense. The above...

Re: Stopping time

Here is a hilarious way to speed up, slow down or theoretically stop time evolution. So take a quantum system, for example an unstable particle, that will soon decay. Keep observing this particle as frequently as possible. So we keep observing the particle that will soon decay. And it never decays,...

Re: A Portrait of reality 2nd edition.

All that's mentioned, from what I read so far, is that galaxies are separating but what about galaxy groups from local to supercluster. Are they separating as group formations or separating within those groups to eventually "unbind" themselves from those structures? From what I've read, supercluste...

Re: A Portrait of reality 2nd edition.

Oh, and we have the nards to call our baseball championship the 'world series' despite not inviting say the Jap and South American teams all of which play a pretty competitive game. Well yeah, but then England had the hubris to assume that Johnny Foreigner couldn't possibly beat a team of eleven En...

Re: A Portrait of reality 2nd edition.

Dear Noax and uwot, Noax gave a value to the expansion rate. He valued it at 1% every 150 million years. Oh yea, I hadn't seen it expressed that way. More like a percent every 140 MY, but yes. Billion I understand to be 10^9. In European nomenclature the same number is called a milliard. A billion ...

Re: A Portrait of reality 2nd edition.

Noax, Can you tell me something? Please. The velocity of a galaxy G near the outermost edge of the universe we can observe is D distance away, and moves with V velocity compared to us. It is accelerating at A acceleration rate. Some things that I think are off-point: The furthest we can see is the ...

Re: A Portrait of reality 2nd edition.

3. I believe I have a very valid point which no physicist or cosmologist has thought of. This should ring a lot of bells if it is a scientific point, not just a philosophical one. If I think I have a valid point which no physicist or cosmologist has thought of, I have a very strong probability of w...

Re: A Portrait of reality 2nd edition.

No, it's only the space between galaxies that's expanding. The galaxies themselves and the stuff in them is largely held together by gravity, EM forces and perhaps dark matter. According to what I've read so far, everthing is expanding, except, of course, space. Space is a given, it can't expand or...

Re: Are You A Garbled Relativist?

A philosophical argument would have been welcome. Instead it was ad hominem - mostly ad hominem against a variety of straw men! - from start to finish. I see what you means. It is indeed full of strawman, begging, and emotional arguments. Even the title is an ad-hom. It could be that to some (there...

Re: A Portrait of reality 2nd edition.

I am awfully sorry, Noax, but acceleration is still not proven with the data you provided. You state that speed and position are both available. But there is no other data about speed and position than what we see now. This would be true only if light traveled instantly. What we see now when we loo...

Re: A Portrait of reality 2nd edition.

Thought I might attempt some of the answers, as best I understand them, which isn't great. Now, this is important: B.1. Was dark matter B.1.a. discovered or B.1.b. hypothesized to exist BECAUSE they knew (or mistakenly believed) that the universe was accelerating outward, and therefore they needed t...

Re: Relativity?

Is 'direction' the correct term to be using in relation to 'inertial frames' and 'time'? No, the correct term is 'inertial reference frame' or IRF. Because for all intensive purposes alpha centauri and earth could NEVER stay synced because they are both moving at different speeds, unless of course ...

Re: Relativity?

Time is the temporal separation between events. You are aware that there is no actual physical separation between events, right? There is very much physical separation between them. If you're going to ask me what time is, you need to use my definition of, among other things, what an event is, which...

Re: Relativity?

Is there an actual 'stationary', which one could ever actually be in? There can be if you want one. Nothing suggests itself. Many people use the ground under them, but that reference is different for every person. Perhaps some object, but I cannot think of one that is not accelerating. The mean vel...
