So much of our cosmology is based on light travelling in fairly straight lines. If light curves on earth because of gravity, that has implications that are huge, astronomy shattering stuff.

Light does travel in straight lines, in a vacuum. GR does describe light being affected by mass. That has been understood since 1919.

Yes, there are all kinds of other possible explanations, however, right now people are denying that things can be seen and photographed that are supposed to be over the curvature of the earth.

I known you're referring to me, but the irony is that you are the one that implied repeatedly that such things are impossible to be photographed if the shape of the earth is what it is, and inferred from that that because they are photographed then either the shape isn't what it is or light bends. I on the other hand pointed out that light refracts, that even the position of the moon can have an effect on the ocean and that we don't have all the factors at hand to consider why or how it is possible.

One of the most recent, and that should be joy for all amateur physicists is that with a modern infrared camera and big zoom lens, you can take pictures easily of things that are over, what should be the horizon. IR travels further in air then other light wave lengths. So, we should be seeing a lot of very long range photos appearing.

These cameras have been in the hands of very capable and highly intelligent and qualified individuals for decades now. Why haven't any of them essentially blown the whistle on the psyop?

Now, is this "flat earth" thing a psyop?
The ball earth thing is definitely a psyop. There is a mountain of evidence that the people we rely upon for this information are liars. There is also a mountain of evidence that says they have lied about this.

I wouldn't call photographs that don't come with any real facts and information as mountains of evidence. You though, are convinced that the conspiracy over the shape of the world is true. There is no denying that. You also think that numerous countries that put satellites into orbit all collude to lie to regular people about the most mundane thing, so that when people observed Sputnik it was the Russian and American governments colluding. The ISS is also a combined collision, with no one blowing the whistle. The irony is that the shape of the world was recognized by numerous people from across the world for thousands of years from simple observations and no conspiracy could be maintained to hide it, despite the church decapitating scientists like Galileo for saying otherwise, and it's still as obvious as the sun rotating around itself if you grab any telescope or even a pair of binoculars and a filter to observe the same sunspot configuration every 28 days, and we can see from the shadow the moon has that spherical objects in the sky is not anomalous, and then there are the other planets and almost 200 moons, and comets.

And there are many experiments that seem to conclude that the earth is an enclosed space. There are also many ancient cultures who describe the earth as an egg / egg shell.

Right now, i am just watching for more data. Don't believe anyone.

Yet you are convinced that the psyop is not the fe, and that we cannot even trust our own eyes as space is only an illusion.
