On a hot summer night (34°C), you are listening to a rock group in a stadium 300 m away from you.
A friend of yours is sitting in an air-conditioned house across the country, listening to the broadcast on the
radio. If the signal travels 33,000 km up to a satellite that retransmits it, who hears the concert first (speed
of signal = 3.00 x 10³ m/s)?
