If you did, you will always have done it, but you will always have used the winning number and will only receive half the winnings. You couldn’t use a draw with no winners, because you will have never won in that case.

Since time travel thankfully does not exist, I’m going to say no it wouldn’t be illegal.

I probably wouldn’t tell anyone that’s how I won it though, since they’d probably have me committed or worse steal my time machine

Three words. Gray’s. Sports. Almanac. Bet on the winner, and you’ll never lose.

please answer quickly i have been waiting since later this afternoon

If you can TT there are way better ways to make money. You can travel in both time and space, or you’re dead like all the other travelers that buried, sky-dove, or spaced themselves… So many forget galactic motion even if they get the solar orbital and rotational calculation correct.

If you can pull off such a feat then get a space suit and hit up the closest M-type astroid. The potential wealth on a single M-type astroid can dwarf all the wealth extracted by humans on Earth in the Holocene; yeah all of it. Planetary differentiation due to gravity is a tyrant that steals away all the valuable stuff in the center of the planet. All our elementally rare materials are the leftover scraps from late collisions after the surface solidified. M-type astroids are the metal core remnants of a differentiated body that was broken up. The wealth they contain is massive and unlike anything humans can access presently.

You want a lottery? I give you a new chapter of humanity and crush the very meaning of wealth.

No, but it would depend on your time travel type. Single universe, branching universe, multiverse. How do you deal with paradox resolution?

When a regular person does it, it’s a “crime.” When the 1% do it, it’s “innovation.”
