Solar System I’ve heard that the Oort Cloud contains trillions of icy bodies. What would be the average distance between these bodies?
Science In the November 2017 issue’s gravitational waves story, Robert Naeye wrote, “If gravitational waves disperse, slower frequencies will arrive at the detectors after the faster ones.” But how are there different velocities for different frequencies? It seems illogical to me.
Solar System, Stars My understanding is that the materials for our solar system and others nearby were created by a supernova. Where is the black hole from that supernova?
Cosmology If not even light can escape from a black hole, how can you explain jets that launch at near light speed extending for numerous light-years?
