I think it's interesting how the radiation that does get through the magnetic field but not through the atmosphere and create the aurora lights that we see.
ReplyDeleteIt is very interesting how the theory of Continental Drift was not accepted until Sea Floor Spreading was discovered. The amount of evidence for an idea to be accepted is a lot and must have good reasoning.
