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...
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.
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.
