Experimente cu mişcarea elicoidală

- 2 alice de plumb, de mase diferite, coboara prin apa din piscina....pe 2 elicoide/2 frecvente ...diferite?
- 2 bule de aer. de diametre diferite. se ridica cu frecvente diferite...din acvariu?

oameni buni mai aberăm mult pe tema spinului cel misterios!? nu e nici un mister acolo și nu e nici un fel de mișcare în alte dimensiuni ascunse! mișcarea de spin e mișcare în spațiul 3D+T la fel ca orice altă mișcare macroscopică!!!!

i have also a problem with this:
"The radius of the central object must be significantly less than 17 light hours, because otherwise, S2 would either collide with it or be ripped apart by tidal forces. In fact, recent observations[16] indicate that the radius is no more than 6.25 light-hours, about the diameter of Uranus' orbit, leading to density limit 8.55×10^36 kg / 1.288×10^39 m^3 = 0.0066 kg/m^3"

now, compare that 0.0066 kg/m^3 with earth calculated density 5.515 g/cm^3 ... wow! ordinary earth matter density many times more that a black hole!? we live on a superdense black hole already?

5.515 g/cm^3=5.515*(100*100*100)g/m^3=5.515*10^6/m^3 wich is ok because earth is waaay more dense that sun, no news here ... but what means that!? a black hole is actually more puffy and less dense that an ordinary star!? and a humble rocky planet like earth!? WOW!

and all its super strenghts and marvelous properties can be only because is way much more matter, 4+ milion solar mass, clumped together!? double wow!

sun average density 1.408×10^3 kg/m^3 now this look more sane, 1000+ tons per cubic metre is ... dense! that's our sun!

Not a problem. The mass itself is in the form of a singularity of infinite density. The radius mentioned is that of the event horizon. The average density within this large volume can be surprisingly small; that of water was once given. --IanOsgood (talk) 04:23, 17 July 2012 (UTC)
formally true buttttt ... what if is NOT an infinite singularity ( real volume → 0 and density ← ∞ )!? ... we can apply here a common sense logic! because the infinite is forbidden to heavenly spheres of a surreal god, for us, mere mortals, what we have is a real thing which is quantifiable and measurable only by this puffy even horizon radius! only that thing is real, plus many time more gravitational pull! which, i see, can bring to us, using an unhealthy form of logic, the strange conclusion that even if a black hole density is lower that earth density still must be infinitely dense because this is what our equations told us! (LE: which can't be true for any real measurement! we can't measure 0 and ∞! real trajectories of real clumps of matter around that black hole is newer 0 or ∞! no matter how small or big or dense or strange is the measured trajectories!) ... so, why not other way around? an equally sane conclusion can be that between gravitational force field and mass density is an inverse relation! not mass causing the gravitational pull, but the independent gravitational field being the trigger of measurable mass effects sensed by our scientific instruments as clumps of matter! ... this way will be no more a need for strange physical objects like black hole singularities with infinite mass density and infinitesimal spatial volume!
