 A straightforward response to this worry is to imagine that the flipping took place yesterday and was recorded on video. The first flip occurred at 11 p.m. sharp, the second flip \(\frac{60}{2}\) minutes later, the third \(\frac{60}{4}\) minutes after the second, and so on. The video has not yet been made available to anyone, but as soon as the player has paid the fee for playing the game the video will be placed in the public domain. Note that the coin could in principle have been flipped infinitely many times within a single hour. (This is an example of a “supertask”; see the entry on  supertasks.)
