That one that deviated from ours shortly after the big bang with the planet sorta like Earth but with a later stage sun and 16 other planets in the system. Specifically the one with higher oxygen content than ours, yellow tree-like plants, and where the main intelligent species looks sorta like 7 legged dogs and sound like they're laughing when they speak.
That would mean less greed as greed let to cheaper options to fuel factories and power cars., in exchange for more profit. However greed is our human nature (sadly). So someone else would have made a point to destroy the environment if it would solely benefit them.
Alas, greed is bred (past sence of breding) into the western societies and then 'exported' from Europe via the US as base for economics to all other areas of the globe. I get the feeling it was 'enhanced' by the middle-eastern trinity of religions, Jewism, Catholism and Muslism (correct spelling?) which places humans above anture instead of smack in the middle of it and totally depending on it.
As a great though experiment start to write to yourself from there and then take on the personality of that person and respond.
What would they say to you? Obviously things go wrong in every universe so how does that alternate universe you mentally frame issues. What decisions do they make when faced with choice.
( trying this with bard led me to being a cyborg this made me like AI more and trust it less)
To be honest, I'd be genuinely curious if they went through their own struggles with expectations, especially ones tied to apparent gender identity. Hell, do they even identify the same way I do? What ripples throughout my entire sense of self could have been caused just by something so seemingly simple?
Would we be even remotely alike?
Probably have consequences on my psyche, but meh. Waking up each day is, too.
Tbh, the star trek TNG universe probably. Go see a post scarcity society, a world where humanity really made it, then go find a job on a starship for a while
I would love to see a world where ww1 (and thus in follow up ww2) would not have happened. So many things in our daily lives have been influenced by the world wars.
Id like to imagine Germany would've become a superstate before it happened in our lifetime. Focusing on industrialization and cooperation with other nations around it to improve the products at the time.
some scifi universe where they hand out anti aging perfect health pills like tic tacs. That would probably be a pretty interesting place to check out for some time. If it's an innate ability to travel and I don't have to worry about getting stuck in a universe, I'd probably want to check out some questions like "what if the Roman empire collapsed way earlier?" or "what if someone killed Hitler as a child?" or "what if religion didn't have such an appeal to people?" (though I suspect I'd be going back to the first universe with the last question).
In the past religion was key to keep the population together under a single purpose. Nowadays that's not needed anymore, but back then the church had a lot of control. Without religion bonding the people the Norms and values would be different than what they are now. However we can't exactly speculate what would've happen since our society was build around religion.
Skip the pill, pick one where you can transfer you consciousness to robots that look perfectly human, but are stronger and faster and all that. You could skydive without a parachute and swap bots if you took damage.
Eh, I don't know, I'm not yet convinced mind uploading is philosophically unproblematic. I'd rather get as much use as possible out of the ol' meat mecha before considering that.
My first stop would be the one where the world came together to tackle greenhouse gases with the same urgency we handled CFCs and the hole in the ozone layer. Not a huge difference but hopefully a big improvement.
I would also like to see what happened in the one we did not handle the CFCs and the ozone layer disappeared, just so I could feel like we aren't complete fuckups in our reality.
To a universe where a version of me that's close to who I currently am has travelled to all the universes I want to explore and made a top 10 list of universes to visit first
I'd probably start with a table of contents universe to see what the various options are. Then I'd look for ones with interesting pathogens, like de-aging viruses, and parasites like in that one episode of Futurama (I just wouldn't be worried if someone loved me because of who the parasites made me into).
Then I'd go visit versions of universes around the present time after I had made various changes in the past to see how it impacted things. The beauty of the multiverse is that I wouldn't even have to ever do those changes in the first place, another version of me would have taken care of it, so I could just jump to the results. Then I could also check out the ones where I failed but still had an impact, they would probably be interesting.
I'd crash Stephen Hawking's time traveler party. I'd be crashing it because I'm not really a time traveler, though I suspect he wouldn't be disappointed.
I'd try to satisfy my curiosity about things with similar laws of physics before checking out more different ones because I suspect it might be difficult to find your way back. There's just so many variables that could change from universe up universe, and each one of those could be its own dimension you could travel along. It would be so easy to get lost, plus there's a good chance I wouldn't be capable of existing in an infinite number of them and would cease the moment I tried going to one of those.
It's possible that in the multiverse, every moment of this current universe is happening simultaneously. So I wouldn't be traveling to our past, but another version of us' present, which just looks like our past. I could go there and cause that universe to believe time travel has been proven and then return to this one and nothing would be different.
Though I will admit that traveling in such a way does stretch the definitions to the point where "is it time travel?" becomes meaningless.
One where history has been altered in somd big massive way wherever that be
no moon landing
heroshima and nagasaki not being blown to pieces
one of the many coldwar close calls that has happened during history not being a cold War close call but instead a bbq so for an example Lt. Colonel Stanislav Petrov not going on his better judgement and reporting the false weather balloons to > higher soviet command or prehaps > B-59 Submarine if if wasn't for one of those senior offices not putting in his key history as we know it would have been altered for the worse
It's threaded with spiraling time threads, like symphonic Christmas lights dancing in an ethereal breeze. Touch one of these time threads, and millenias worth of physics explodes along my skin. You can hear the whispered susurrations of cosmic eddies trembling thru the universe, the songs of stars. It is bright like sherbert, cold and warm on the flesh, and every fiber of my being is rapturously tesselated.
