Visit the library of Alexandria before it burned, just to see the insane amount of books.

As someone else commented, see how stonehenge was built/used.

Find out how the Antikythera mechanism worked and how it was used.

Witness the construction of the pyramids.

Experience the telling of the norse mythology.

I would go back to when this post had no comments and be the first so I can explain to everyone else what no consequence means. That way when I come back to the present I can still be disappointed by half of the answers in this thread.

Go back in time and stop diddy from diddling so bad.

Probably see the dinosaurs in the late Cretaceous. Just before the KT extinction. I want to know how accurate we are about what dinosaurs looked like. All we know are from the bones and some fossilized skin and feathers here and there. I bet there are a TON of animals we don’t even know about because they were never fossilized. What did the T-Rex use their little arms for? Were dinosaurs covered with waddles, weird skin flaps, some hairy stuff, and what color were they? For comparison, if we drew modern animals like we draw dinosaurs from just their skeletons:

I’d love to get the chance to talk to Isaac Asimov and talk to him about the future and how he decided to start releasing his stories. Probably around 1972 because I liked bicentennial man a lot.

Other than that:

• go back to see socialist radical anti-authoritarian Jesus do his real protesting instead of the biblical king washed stories.
• or go back to the fall of Amen to see the end and beginning of monotheism of the modern day and understand the actual departure of the worker force
• see if I can find the actual great flood that all the myths seem to talk about and see if the conspiracy of it being about the Mediterranean basin is true. So probably Mesopotamia time and hope it’s recent enough memory to hear actual stories.

Assuming no consequences means I won’t die, or catch a disease or something, I’d go back like a hundred million years or so to look at dinosaurs.

Camera in hand, time to visit Chavín lands! They’re one of the earliest recognizable societies of the Peruvian Andes. Given that a language barrier would be true for pretty much any “too far back” visits, might as well go with one that I’m really damn curious about!

I would go back to ancient Rome, Athens, or somewhere similar and just do turism.

It would be incredibly cool to just look around and feel it how the world has back then. Video games like Assassins creed Odyssey scratch that itch but it would obviously be cooler in real life.

I’d like to go back many times to earlier in my life and try different dialogue options.

Like that time you thought of the perfect comeback two days later?

Or just learn how people act and react. If I say this, they react that way. Now if I say that how do they react?

I would prefer to go back in time literally 24 hours and HAVE consequences.

I would not eat the food that likely gave me food poisoning.

Go back to see how they built Stonehenge

(Assuming that “no consequence” also means that I won’t die on the trip…)

• Witness the Tunguska impact.

• See a Beatles show when they were just some small time dudes playing in a crummy club.

• Visit the Great Exhibition of 1851 and go inside the Crystal Palace

I’d go back to fuck at a Roman bath house in ancient times. Fuck it, no regrets.

• Kill as many communist leaders as possible

edit: FUUUUUCK NO CONSEQUENCES HOW DARE YOU

I’d go back to the Yukon Gold Rush and make sure Fred Trump never made it out of Canada.

Edit: Doh! No consequences… huh. I’m not really sure it would be worth the trip then.
