Truth be told, we are * already* time travelers.
After seven days I found it impossible to edit my post. They are inevitably locked in a blockchain.
I totally agree with where you are going with this idea @rok-sivante. There is already part of the future and past right here. I see it in the granite quarries exposing the faces of layers of rock. There I the quarries in Illinois far from the Sea I found fossils of creatures who could only live in the sea.
Honestly you must have taken hours to put this together and I don't think your gonna get that time back. Sorry to see so much spam in the comments.
mmm, actually this one came together in probably about an hour. though, the idea has been cultivating for months.
no worries about the spam. I take a pretty hard stance on it and typically reply with links to posts I've written explaining it, with a full upvote - so they end up getting turned into both lessons for the offenders & onlookers, and more SBD in my wallet. lol. :-)
