The article on the theoretical possibility of sending messages back in time via quantum entanglement made me wonder if it might be time to try again with Stephen Hawking’s secret time traveller party, but this time at a quantum scale?
The reason why we haven’t seen messages from the future might be that we haven’t noticed them, just like if we sent mobile phone texts back to Victorian Cambridge! Perhaps we don’t need to figure out the exact mechanism, just create a simple miniature alphabet or code that we can easily monitor with a quantum computer? It’s then up to the future to do the hard work. I can imagine, though, that if successful, it would be very dangerous for geopolitics, so perhaps we should just stick to the long route to the future!
