None of the methods of time travel discussed holds any hope for objects like human bodies to be able to do it. And why travel in time anyway(14/21 December 2024, p 54)?
Even assuming it were possible, the dangers would be enough to make it unthinkable: diseases to which one had no immunity, for instance. Not to mention the risk of being involved in complex and probably fatal social situations. Above all, the logical puzzles of doing something like causing the death of one’s own grandfather is enough to stop the enterprise.
A better bet would be information transfer. Isn’t this more likely to be possible? One can imagine miniaturisation reaching a point where we can make cameras that are small enough to go through a wormhole and transmit data.
This would also address an issue often raised by sceptics. If time travel is possible, people at some point in the future will achieve it. So where are they? Well, if tiny cameras have already been sent back to see what we are up to, we may be surrounded all the time by hundreds of them.
