comment Bear with me, this is a stupid question. Talking on the phone and time
Back in the day, I made a number of international calls that were routed by satellite and suffered from the delay. I found it took training to make the conversation work. It seemed that it came because I would say my piece and signal (by tone of voice, etc.) that I was done. When I didn't hear a response after the expected time, I would conclude the other person had nothing to say and would start talking again. Their voice would come in and we would be talking over each other. With training, you could make it work.

comment Magnetic paradox in relativity?
Are observers A and B the electrons? If not, please do not reuse symbols. If so, neither one sees a relative velocity, so they are in the same frame.

comment What does it mean to increase volume by X decibels?
$Y$ in the second equation is in bels, while in the third equation it is decibels. This is clear because $\frac{P_2}{P_1}$ has two inconsistent expressions.

comment Are there planets that do not rotate on their axis?
If you think about the phase space that truly zero rotation represents, you will probably convince yourself that all planets rotate at some rate greater than zero. This does not prohibit planets rotating quite slowly.
