21:55 ...when these particles come into the atmosphere well
22:03 they're coming in very very fast between eleven and about 73 kilometers per second that 73 kilometers per second is
22:10 a sum of the Earth's orbital velocity as well as the escape velocity for a
22:15 particle in orbit about the Sun so they can certainly be faster but then we're talking about things that have an
22:21 interstellar origin
