Edit: Sorry i totally misread your questions, as i am speaking to someone at the same time.

You could go far into sea nearby a working lighthouse, and do the math yourself, and see howmuch curve there should be for you not to be able to see it, but you do.

Original post: Why, after all these discussions, you dont research yourself? There are a lot of good videos about the different tests being done as far as 100 years back.

There are alot of videos from airplanes that show you the moon far below the horizon, or videos of the moon and sun being surrounded by clouds. Thats should not be possible.

Also the stick test fits the sun being close much better than being 93mil miles away.

Also, why does it take them so much to explain how things work here and in the universe. In the end, that are all theories, nothing is proven. They annouce way ahead, there might be something something out there, they are making formulas and equations that they present years later. But most of the time it has a unknown variable they need to add to maken the equations work, but admit they dont know yet if it exists in the first play. And that mssing thing is presented years later as proof. But you dont see anything but cgi and photoshop.

Final thing is inertia. They are stating that everything feels motionsless because of inertia.

You probably learned about it how it feels in the train, going fast but hardly notice notice it. Bit that onoy works inside a container with its own pressure level inside.

So how can it be that we have that when they are claiming that our atmosphere is flowing over to the notingness of space. No boundarirs

Imagine going in a train without a roof and windshield. Crazy. But that tells me that we are most likely in a closed system too. Also that Bill Nye guy stated on video that we can not leave thid place, we are closed in. We can not leave the earth.

So just take common sense instead of all these difficult, hard to explain equastions and just look into it.

Nasa fakes everything.

Good luck.
