if u fell u would hear sometthing like yeaaaaaaaaaaaaaaaaaaaaaaaaaaaa­aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa­aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa­aaaaaaaaaaaaaaaaaaa ooooh a neutrino :) aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa­aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa­aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa­aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa­aaaaaagh *squelch*

What if someone fell into that hole? Oh God...

In contrast to what I suggested earlier, solar neutrinos are generally presumed to not be antineutrinos, although the Majorana neutrino is also an antineutrino, and neutrino flavors can mix, with the mix varying over time and thereby losing and gaining mass, but that's another topic. Also, the size difference in the neutrino image of the Sun is probably mostly a scattering effect rather than terrestrial lensing.

I wrote that "observations of cosmic ray particle families apparently indicates most of the energy has a 2-D sheetlike form." I forgot to mention that this is an effect that supposedly becomes apparent at cosmic ray energies around 1TeV and above.

Solar neutrinos are supposed to actually be anti-neutrinos. Seems antiparticles could have negative mass, cosmic rays involve a mix of positrons and electrons and observations of cosmic ray particle families apparently indicates most of the energy has a 2-D sheetlike form. Seems to me this is the matter part of the beam going one way under gravity and the antimatter part going the opposite way.

If the sun's electron-anti-neutrinos gain energy on their way up to the Earth, to thus include a mix of muon- and tauon- anti-neutrinos, then maybe these antiparticles are behaving in an antigravitational way. A full pass through the Earth has been used to image solar neutrinos and the apparent neutrino-imaged radius is 5 times the sun's optical radius. It's probably possible to tell whether that is gravitational focusing or anti-focusing, as the curvature must be small it suggests the latter.

LMao.... Nice.

become a catholic. 10 hail marys and you're forgiven for everything. you can wait until the last day so no rush.
