You find a time machine and go back 1 million years then realise its only good for one time use. How do you leave a message that will last a million years and what does it say?

  1. I’d write a note to myself: “Don’t time travel back a million years, life sucks here. Try going a million years into future instead. Also Peter is a prick don’t go out with him”

  2. I’d begin by making a star chart, this will allow the message to be dated. You then want to find a type of rock that will do little to no erosion within that kind of time scale. That is extremely important because something like granite would erode by 100 inches within that time scale. (1/10 of an inch every 1000 years) and so would not make a good source of message delivery. If you have paper or something and want to use it for the message. I highly recommend using amber to preserve it. It’s a really good resin that’s capable of preserving even bugs and such for millions of years with little to no degradation
