OK, so ‘Monthly Mailbag’, might have been a slightly over-ambitious title. But we’re back answering questions from the comments section, this time on the stick topic of gravitational waves. Do the gravitational waves of black holes affect us here on Earth (0:27)? What’s the difference between gravitational fields and ethers (1:15)? Why do we think gravitons should exist (2:53)? Does the Earth’s weight change over time (3:53)? Jon explains all.

Watch Sheila Rowan’s full lecture on Catching Gravitational Waves here:

After Sheila’s talk, there were loads of great questions about the nature of gravity and gravitational waves. This month, Jon dives into the murky waters of the comments section to explain a few of the finer points.
