Thank goodness for the Internet for addressing questions that we’d never thought about previously. Physics blogger and dad Chad Orzel has a daughter who loves Goodnight Moon. This has given Orzel occasion to read the children’s classic more regularly and discerningly than he might have otherwise, and it’s led him to a surprising discovery: The bunny’s bedroom in Goodnight Moon just may be moving “extremely high velocity relative to the earth, so that relativistic time dilation makes the six-minute rise of the moon appear to take an hour and ten minutes.
