All good answers, but the simple fact you were not self centered but curious and asked what OP would do back, made your answer great. Thank you. Up vote freely given.

Go back to when I sold all 100+ Bitcoin for like $5 each and tell myself "no".

Kick my dad in the nuts on my conception night

• Going back to slavery and beat some slave masters
• Meet my mom when she was younger, maybe in high school. Tell her that she seems like a lovely young lady and very smart. I don't think she heard that enough.
• Go back to the first day I got my first cat.
• I would like to see a royal party of some kind.
• Go to a Shakespeare play while he was still alive.
• Go back to where my grandma alleges she met Bill Cosby to confirm if it's true, and, if so, punch him because apperently he was rude as hell.

I’d go back to “old enough to understand but still young enough to do something about it” me and have a nice long conversation 🙂

Option 1: Attend Stewen Hawking's time traveller party - he likely won't expect someone so dumb though
Option 2: Watch and experience Warsaw Pact invasion of Czechoslovakia - I often hear our conservatives argue this was actually friendly

I'd definitely try to record everything in both cases.

I can't really answer without possibly breaking some rule... But my destination time would be exactly nine months before my own birth date...

At first I thought you meant "go back in time 24hs" in which case my answer would have been "yes! And get my haircut elsewhere!!!" But seeing what you mean for real, and with no consequences, I'd go back in time to see extinct animals. Shame I can't bring photos back with me

Initially I read that as “you can go back in time for 24 hours” and thought why would 24 hours ago be that interesting? :)

So my initial answer is: Not eating the late night burger I had last night.

My final answer is: San Francisco in the 60s/70s to hang out with the Dead and all the other amazing artists of that time. Maybe see a show at the Fillmore.

My two choices:

• Pontic Steppe, around 3000 BCE. Likely region where Late Proto-Indo-European was spoken.
• northern Lazio, around 650 BCE. If possible/reasonable I want to spend a bit of time in an Etruscan city, then in a Faliscan city, then in a Sabine one. I'm OK travelling by foot if necessary, as long as there's always people talking around me.

In both cases I want to be able to record everything people say. Preferably video, but audio is good enough. I just want to know better about languages of the past.

It's kind of tempting to include 1450 Uruguay as a choice, since we barely know anything about the Charrúa language. However the Charrúa weren't exactly friendly to outsiders, so this option would be only if neither side can interact with each other.

Gonna go see some dinosaurs

See Jimi Hendrix live.

• Go to Teotihuacan to see how non/hierarchical it was, maybe trip balls if the opportunity presents itself.

• Go to Harappa or Mahenjo Daro and see how indus seals were used.

• Kindly ask the Minoans if that topless lady holding the snakes is in charge.

So many bands I'd love to see! But that's somewhat small fry, so to speak, so ancient history, if I could travel to a different location also instantaneously (guess that'dhave to be possible or else it'dbe pretty boring or hard work!). Ancient Egypt, Greece, Central America Mayans... but then, are WE immune from consequences also?! Free from contracting diseases, free from being sacrficed to a god or getting enslaved?! Can we communicate with them?! Dinosaurs would also be awesome, if immunity was guaranteed....chomp!

Or perhaps just see my dad again :)

I'd try to meet the Buddha, and see if he could shed some of that instant enlightenment on me. In the stories, he seemed to be able to say just the right thing to people to wake them up out of the matrix.

My first answer was "buy Apple stock" but no effect on the time line probably means I don't make any money. (well wait, what about enlightenment then, does that come with me?)

Attend the 1934 Nuremberg rally.

Not keen on the politics of it obviously but you can't deny the nazis knew how to put on one hell of a spectacle.

Prevent myself from being born.

I wanna see Carthage

I think it'd be neat to go to like 10,000 BC and just live a day in the life of some tribe/ancient city.

Go back to the moment when the current highest level administrator of Twitter set the password. Then when I come back with the password. Now in the present, I log in and delete the entire twitter server.

History didn't change, I just went back to retreive some information to be used in the present.

😈

I could finally ride every ride at Disneyland.

Choose the last non winning lottery numbers. It’s currently at 130 million. There was no winner. So it shouldn’t affect the time line. If op thinks it does I will revise my choice.

If I can transport things back and forth, I would probably go and max out a credit card and buy all of the gold that I can to bring with me for trade.

Then I would go to the library of Alexandria and use my cell phone to get photocopies of as many books as I possibly can, and in the downtime I would go to any open Street markets and purchase any cool relics that I can find.

Then I could come back and share some of the Lost books of Alexandria with the world and also have period correct relics that have somehow magically not been exposed to a thousand years of environmental corrosion.

Then again, that would probably also mess up their radioisotope dating but I don't know if it's specific enough to only cover a thousand ish years.

Maybe if I have a little more time to prep I can find some place that I know hasn't been Disturbed and like put them in an airtight safe and store them for me to go back and ReDiscover now.

Ops mom.
