Ah no Wat, I meant to look at one's own past, sort of like a video recording of things that happened in the past, without the ability to change them. That was in an Asimov short story. The viewer was able to see events in history without being able to interact with or change history.
Wat, based on that, it sounds like using the special relativity speed method would be easier than trying to manufacture a source of gravity that strong- you cant get that close to a micro black hole without being destroyed
Stellator- I like the two gravity field method but based on Wat's calculations it sounds like that would be beyond our level of technology for a long time.
Uploading our minds sounds like a better idea, as long as our bodies at home get to share in the experiences!
So based on how long each method would last- would you say a few hundred years for suspended animation/croygenics, a few thousand years for the gravity field method and virtually unlimited for the uploading method?
Ha I love that term "meatsack" I remember it from Supernatural. And transhumanism's time has come as well as lifting up animals!
