I logged onto my Amazon.com account today to discover an item of mine had been delivered early. What surprised me is when I tracked the package via the UPS website for more detail, I discovered they had invented time travel! They haven’t got it quite right yet though, because my package ended up in the wrong state.
In my mind, someone was very confused to open the package and find a Blu-Ray movie, before the format was even released…
Imagine if you could send packages back in time (without altering the timeline, i.e. the parallel universes approach). I would send myself a top-notch laptop back to 1991, because I was still using a 10 year old computer back then. I would also send myself a friend who knows a bunch of martial arts back to 1988 to kick a few arses.
On the other hand, what could your past self send you in return? That one is a little easier… you could just put something in a drawer for a number of years and it would have time travelled (unless it is food). You could ask your past self for a couple of shares of MSFT or GOOG. I, on the other hand, would gladly exchange the laptop for just one curry from my favourite Indian restaurant in England, which sadly shut its doors last year. R.I.P. Mughal Dynasty.
