I find time travel to be very intriguing--and possible someday! Right now--it's possible--albeit now in dreams. I have had multiple vivid retrograde time-travel dreams.
IMHO, it remains to be decided whether time is a kind of energy or matter; I wonder if there are particles called "chronitons", or if time exists in the form of waves. Time is thought of as the fourth dimension. The known three dimensions can be manipulated, so why couldn't we somehow manipulate time--assuming it's a kind of energy or matter?
Next, we would need to develop technology to manipulate time.
If time travel is proven to be feasible, think of the possibilities!
I believe that time travel would be a VERY lucrative form of tourism! For example, I could take my camera along with me in whatever time machine there is, and bring back lots of photos from the past.
Whether people in other times could see you or not is not known. Or whether your presence in another time (past or future) would affect the timeline.
I would like to go back into my childhood with my camera, take photos of the operating rooms I have been in (20-30 times already) and other places I've been to, even my house as it appeared back then.
I would also go back in time to my local airport (FWA
) (as it was in mainline days) and take lots of photos of the DC-9s, 727s, and other mainline jets that visited it back then--and then submit these photos to A.net! I wonder if they would accept my "time-travelled" photos??
On a larger scale, if I were able to introduce time travel as a form of tourism, it would be quite lucrative. Just think of the possibilities of sending "tourists" back in time to their chosen period of time (even before their lifetimes), with cameras! I bet people would pay big money to do this! The infrastructure would be like Star Trek's "atavachron", with a whole library of historical time periods that people could be sent back to--and hopefully, return from! Do you want to revisit your childhood, or have you always wondered what it would be like to join a wagon train across the Western frontier, or relive the Renaissance?
I'm currently writing an autobiography; retrograde time travel (with my camera, of course) would provide so many pictures from my past (my surgeries, my family life, all the places I've been, school life, speech camp, etc) that would supplement my memories (which inevitably fade with time), as would any documents and artifacts I managed to capture from my past. These photos, artifacts, and documents, many of which I have never gotten to capture in real life, would be invaluable historical documents on my life, not just memories. In other words, using time travel, I would be able to capture as many photos as possible, as well as many of my documents, my old toys, and other artifacts as possible (which were lost in my real life).
The possibilities of time travel are endless.
