To the future to see if humanity survives my lifetime and, if so, Then back to my time to "invent" future tech. Or if humanity doesn't survive, I'll try to think of a past to go to.

Remember when that lottery reached a record ~$1.6 billion? I’d hop back and win it at the drawing before it hit $1.6 billion. No split for me!
I’ll just relive the couple years it’s been since. Maybe stop a couple incidents from happening (like Kawhi Leonard leaving SA). Use the other time jump later on for a heretofore unknown purpose.

Then again, maybe I should travel back far enough to stop Trump from ever becoming a problem.

Better yet, collaborate with people smarter than myself. Come up with a plan to stop, or at least greatly slow down, the destruction of Earth by introducing certain technologies and discoveries early enough that such things as fossil fuels never become major industries. Do.... do you guys think that would work? Maybe? Help me out here.

I just want the chance to fix one MAJOR mistake that I made: I'm going back to December 2013. My ex-girlfriend (we had broken up the last time in 1998... yup, 15 years prior) had changed her mind and was suddenly doing all the things I always wanted her to. Showing me love and affection, wanting to be around me, saying all the right things. And did I fall for it? Yup. Worst mistake I ever made.

I go back to 1972 and hand my 6 year old self a long book where I've written everything down that she should do differently and what to avoid and what to embrace....then I come back here to see how it all worked out. Then I write a best selling SciFi book about the whole thing.

I use it twice for the exact same time I'm in now and end up with 3 clones to takeover the world with.

I'd take my phone with a few flash drives and a solar battery charger back to about 1965 and give-up the seat to my 18 year old self. Then continue on to about 1898, staying on for the duration. I'd find Mark Twain, Thomas Edison, Susan B. Anthony, H.L.Mencken, George Schuyler, Zora Neale Hurston and Wilhelm Reich to show them the future and enjoy their reactions. Oh, and because it was more fashionable then than now, I'd seduce Clara Bow and hopefully,,, enjoy her reactions too.

I'm assuming the second trip is an escape hatch.

I'd go forward only.

There is at least a chance things might be good.

The past. Even the near past is not a good place for us split tails.

As recently as the 70's a woman could not have her own credit card.

I would travel back to see my Grandfather one last time. I didn’t get the opportunity to say goodbye to him. I would just like one more chance to tell him how much he influenced my life. And thank him for everything he did for me.

First, I would set an age to which I would decide to be cryogenically frozen. I say age 70, 37 years from now. We should have the technology to properly freeze people. Then I would travel something like 500,000 years from now. I get to see if we die off or spread throughout the galaxy. If we survive and spread, by that time we should have figured out how to properly thaw people and even reverse aging, as well as all sorts of genetic manipulations. If we survive and figure out how to travel the universe, I would like to exist then. Then I would travel back to a younger version of me and enlighten me with this knowledge. If we exist, I would have myself frozen at a set time. If we don't, then I won't worry about freezing myself and would live all my years out to take in all that I can take in.

I would wait 2 weeks, visit a different time, then go back to one week after I got the machine and tell myself to go somewhere else. Rinse and repeat.

Need more info. Do you stay the age you are now or get younger? Do you retain all the info and experience you have gained or do you lose it?

First time I go back to my 21st birthday. Stay there for 10 years. On my 31st birthday I go back to one second after I used it the first time so the machine don't know what to do, hoping it will sent me back to the beginning on my 21st and repeat an infinite loop where I am always in the best part of my 20s !!!!!!! ???

Very first thought is to go back to when my Granny was still alive and tell her about how life is now, show her pictures of my niece, nephew, and other important people in my life, ask for her advice on things that I've struggled with since she passed, and just catch up in general. I think I'd use the second trip to talk to her again, maybe at a later time when I really need her again.

It's weird that I have such a hard time believing in religious and spiritual things. I think wanting so badly to reconnect with my Granny is the one thing that keeps me hanging on to believing that MAYBE something out there is real.

And now I'm crying. ??
