We will assume that, someday, advanced beings will exist with exceptional powers. For example, if future humans ever develop methods for altering past events, then perhaps they would be trying to send us a message from the future. Technology should be sufficiently advanced for a future researcher to insert a message inside the frame below:


We await the appearance of a message.
