I'm jealous. As a newly retired fella, I wake up every morning not knowing or caring what day it is.. That's kinda the same thing right? ??

I was just getting used to ATOM now back to syd,  this is the perfect thread for you two.

Maybe if you travel to Sagittarius A* star you could time travel (or just be another squashed bug inside that great superblack hole in the middle of the Milky Way keeping us all in our respective places. This is quite interesting for those who love Cosmology.

Oh, got to put one more from Dr. Becky who speaks Einsteinian Mercurianism!  ?? (and how that affects GPS in your phone or car systems).

Time travel isn't easy.  But if you travel out to our black hole, as close to the speed of light as your technology will allow...then fly around the black hole (a very heavy object - time slows around heavy objects) as fast as you can....then fly back to earth at those speeds....you will arrive to earth in the future, compared to the amount of time that you and your body experienced on the journey....because time was traveling slower for you.     How much time in the future you return depends on how close to the speed of light that you traveled at, the mass of the black hole, and how long you spent there doing donuts (Dunkin') around the black hole.

The general thinking is that you cannot go backwards in time (the whole grandfather paradox thingy).  Although...if you believe in the many worlds multiverse...where the universe splits at just about every decision you make, then going back in time to a different branch could be allowed since it won't matter what you do in that universe because it doesn't affect the universe branch that you left.

So, basically, the short answer is No.     (we can't send you anywhere fast enough to make a noticeable difference...and good luck figuring out how to hop universes)

It's a fun, fanciful idea. I've read where you would have to travel faster than the speed of light, which apparently is impossible.

Impossible right now, but in the future?  Or perhaps on another planet?

And I wake up every day knowing it's Saturday. So I guess I time travel backwards in time every night. Or maybe I too am just retired. BTW why to they call it retired anyway? Seems like I was just tired until I stopped working. Now I can just nap and not be "re"tired or tired..??

In theory... Yes... It has been suggested that the Universe it self may a hologram.. And that there are multi-verses playing out history where scenarios end with a different outcome... Which makes the idea of a Matrix plausible.. I find this shit fascinating as all hell
