註釋

In this novel, scientists at Cambridge University attempt to send a message back in time to warn people of the coming troubles now facing the Earth. To do this they will use the hypothetical Tachyon particle, which travels faster than the speed of light, projected towards the astronomical position the Earth was in at the time the message needs to be received. The message also needs to be sent in such a way as to not cause a Grandfather Paradox and make the situation worse.
