The discussion revolves around a forgotten particle resonance experiment, with participants attempting to identify it based on the description of its setup and results. The focus includes aspects of gravitational time dilation and the conditions necessary for the experiment, as well as its historical context.
Participants express varying interpretations of the experiment's requirements and implications, particularly regarding the necessity of vertical distance and the conditions under which the experiment operates. No consensus is reached on the exact experiment being referenced.
Participants mention the historical timeframe and specific conditions of the experiment but do not provide definitive conclusions or resolutions regarding its identity or implications.
What was the conclusion? Some kind of detection of cosmic rays?MagisterMomentum said:TL;DR Summary: I'm looking for the experiment I forgot it was exactly.
As above: there was, I believe some kind of particle resonance experiment: it doesn't work when the level of resonating particles was the same, but raising part of it up by 20-30m (60-90ft) does the job. Could anyone remind me what it was? Thx.
No, it was completely 'earthly local' experiment. And I believe it was done on some US university or official institute connected to it. And I do not remember the time, but I believe it was done in '70s or '80s of 20th century... But I'm not sure finally.pines-demon said:What was the conclusion? Some kind of detection of cosmic rays?
Oh, yeah! --- i believe we are very close, if not even at the point! --- could somebody tell me in short, why this vertical distance was necessary to fulfill the experiment? There was something about energy, it means the vertical distance creates necessary conditions impossible to fulfill in the horizontal plane: so why it was so? Or maybe it was another experment, but in some sense similar?Ibix said:Sounds a bit like Pound-Rebka, which detected gravitational time dilation. I wouldn't say it wouldn't work when the two parts were at the same level, though. It would correctly detect no time dilation.
Gravitational time dilation depends only on altitude, so you would only see a difference in frequencies when one group of atoms was at a different height from the other and therefore time dilated with respect to the other. You can do the experiment with both groups of atoms at the same height, and you would see no frequency difference.MagisterMomentum said:somebody tell me in short, why this vertical distance was necessary to fulfill the experiment?
