The idea of having a time machine has lingered in our imaginations for a long time. But we also know it will be pretty impossible to go backwards or forward in time from the technical perspective. Not only do many mathematicians and renowned physicists say it’s impossible, but even thinking about the implications blows our minds so much we probably can’t even understand how one would get started on solving this problem.
Surely, we understand a time machine isn’t as simple of a technical problem, as lets say a federal government health care website (in that the engineering solutions are known), it could still be “hacked” in some crude form. And by “Hack” I mean a crudely and quickly putting together system that could deliver the objective.
So maybe a hack exists. Just mental time travel. Rather than space-time travel.
Some possible reasons for time travel:
1. To make smarter decisions (give myself advice)
2. Help others
3. Save time
4. Nostalgia (re-live the glory days)
Time travel seems to be thought of a physical journey, but what if it was purely mental or emotional – I think it’s possible to meet these outcomes without having to deal with 3 dimensional time travel.
I think the personal diary, or a time-capsule, blog, or annotations like the ones from Genius.com, fits this kind of framework.
By keeping a diary someone can revisit the past to learn from failure or success. The past can also provide the previous perspective they may have lost over the years (make smarter decisions/give myself advice).
Annotations are the other way, where they help the next person “forward through history” since your experience added additional information to the literature they were reading (saving them time from having to research the item themselves and potentially make a mistake). This also helps other people.
By leveraging technology and good note taking, I think we can all experience some benefits of time travel.
