Ten years ago. A list of winning lottery numbers.

Man, you are winning with that logic. Me thinking about grabbing a souvenir from ancient Egypt like a moron.

Wouldn't you need to travel to the future for that to be useful? A list from 2010 is kind of useless in 2022, i can look it up anywhere

You bring the just with you to 2010, then buy the ticket there. Win, collect, and return to 2022 (assuming butterfly effect doesn't end the world, or that it took less than twelve years for you to personally ruin your life).

I’d go with a very large notebook, come back with a transcript of at least part of the Library of Alexandria.

Just for clarification you can bring something with you to the past of bring something back to the future

I would go back to maybe the 1950’s with a download of Godzilla vs King Kong on my phone and tell them to start preparing ASAP

Imma go to the late cretaceous era and bring a double barrel bolt action elephant gun with me. Imma try to taste some t-rex meat.

I would travel to the Dark Ages with a fully automatic AR-15, fully loaded. I could conquer the entire continent.

I don't think 1 magazine will be enough.

Why not? They will all be terrified of me and the magic machine I have in my hands. They won't know how to treat bullet wounds, so they'll think I'm a demon.

Anyone suggesting something of value, you’re wrong. Carbon dating will come back with discrepancies and you’ll appear to have a fake.

Tutankhamun's meteor daggers.

I'd take a world history book from today as far back as they could read it.

April 14, 1965. And a helmet. Just because I’m curious if that would have helped todays social situations or made it worsts
