We all know that neutrinos pass directly through things, even big things
such as the earth.
However it is also known that neutrinos interact with matter as a result
of the Z boson or neutral current. This results in small amounts of
momentum transfer and people have looked at whether this is measureable,
e.g. by making neutrinos bounce off things that they hit at a very
shallow angle.
If matter deflects neutrinos in this way then does this mean that
neutrinos that pass through, for example, the moon will get very
slightly deflected, in random directions, such that the moon ends up
acting as a neutrino diffuser. This will mean that if you are far
enough away the moon will cast a neutrino shadow. Is the earth/moon
distance sufficiently far away such that we are in a solar neutrino
shadow during a total eclipse?
No one seems to have considered this possibility, but it seems not
unreasonable
