comment Do gravitational waves travel faster than light?
"Speed of light" is a phrase that needs to be abolished, replaced with "Fundamental Space-Time Constant" or "Universal Speed Constant" or some such thing. It has nothing special to do with light, but with all massless and near massless things.

comment Conservation of momentum in a baseball
Any moment of friction between the bat and the falling ball isn't going to stop the ball's downward motion. At most, since it's only on one side of the ball, it'll torque the ball, adding spin, and slightly decrease the downward momentum.

comment How did they take photos of Jupiter?
The most direct source of information for this image is at ciclops.org/view/97/Io-Transiting-Jupiter CICLOPS is where all Cassini images are released to the public, simultaneous with NASA. You won't get any closer to the horse's mouth than that!

comment What is the minimum pressure of a medium for which a sound wave can exist?
Radio astronomers study density waves in the interstellar medium. Is there a lower limit to a sound wave's frequency?
