It would, but that would mean time travel should be a regularly occurring thing. Which, personally, I think breaks that model. Michio Kaku has a whole thing about this, but, for the life of me, I can't find on the internet. I know it's in a book of his, but I can't find an online source. 

The problem is that, currently, there's nothing to suggest any contraction will ever occur. And we have a lot of overwhelming evidence that the universe was created in the Big Bang from a single point.

It very much is. A closed universe must collapse in on itself. 

That’s not how expansion works, though. The universe isn’t your car. You can’t just hit the brakes later on and slow it down. You need gravity to do that. But as expansion accelerates, the distance between objects grows, and the attractive property of gravity between objects becomes weaker. Gravity is an incredibly…

For us on Earth, yeah. Just live your life. For exploring space, you could face a lot of quirks that could mess things up. A donut-shaped universe would make time travel possible at FTL speeds. Things like that. 

I know it has, but I don't buy it. At least, I don't want to without proof. It limits the universe in a way that doesn't sit well. It wouldn't be as much fun. 

You’d have to explain why expansion is accelerating.

A donut shaped universe would be crazy. 

Basically a closed universe means that gravity wins out, and we end in the Big Crunch.

One thing about models of the universe, you can’t take the names of the shapes literally. If the universe is flat, that doesn’t mean everything is on the same plane and you can’t go up or down.

Ok, boomer. 

No. Because you’re comparing a religious belief system to a group of people that existed when Han was alive. There would have been news stories confirming the Force existed. Video. Eyewitness accounts of battles. Footage of battles. Not to mention thousands of years of actual history. They’re not fables that were…

The point is that it doesn’t make sense. Lucas never planned anything out past ANH. Everyone should’ve been extremely familiar with Jedi and the Force. Everyone should’ve known maybe a second cousin that could use the Force, but maybe not that well. The fact that Jedi couldn’t hone in on Force users and regularly…

But Han was in the military. They wouldn’t sugar coat what a Jedi was. He'd know their abilities. There would be no reason to tell them the Jedi can't use the Force. You don't tell troops the Germans are coming but they don't have guns. It doesn't make any sort of sense. 

It’s the only thing they're famous for. Why would he accept that Jedi existed, but that there was nothing special about them? It would be like believing horses exist but they can't carry people. 

So, the one thing they’re known for, and famous for for literally thousands of years, is the one thing he doesn’t believe?

I think you skimmed over the part where Han actively denied that the Jedi and Force even existed, which is my entire point. People didn't deny Washington existed 20 years after his death. Han denied the Jedi and Force existed 20 years after the Jedi were wiped out. Myth doesn't even come in to play. 

But nobody 20 years after his death, who were very much alive while he was president, denied he existed. Or that he wasn’t a general.

But Han didn’t live in a bubble. He joined the Imperial military. He would’ve been told about the Jedi. He probably would’ve had general orders about killing any living Jedi or Force user on sight. As far as the Emperor was concerned, the only real threat to him or his empire would be Jedi. He would’ve made sure that…

Okay, sure. But the Jedi weren’t killed off 240 years before Han was born. They were killed off while he was still a kid. He would’ve had contact with soldiers and stormtroopers that could verify the Jedi were real. The Emperor specifically mentioned the Jedi when he became emperor. Han was very much alive and well…
