>>>12929278 PM: Is China building a time machine?
Don't build a time machine. Build the antenna for receiving messages from the future. Let the future figure out how to build the time machine. You don't get ahead by building a time machine now. Likely the only use is to send information back in time, so you'll need a receiver for that information back at some point in time X. You win the fucking game by having the receiver first because that future civilization will have a target in time that will be before any other target. Think about it.
