The theory of an invisible magical force doesn't need proof? You're all fucking insane, there's no reason here just mad men pushing a giant lie and conspiracy.
What is your definition of proof of existence? If we assume that it exists, all things make sense. If we assume that it doesn't exist, nothing that relies on it existing works anymore. I can say that gravity, however you want to define it, will always do the same thing we expect it to. Whether you want to call it gravity or ytivarg, it doesn't matter, it exists because there is no proof that it doesn't exist. Maybe you are right, and what we call gravity is actually some mysterious force + some effect due to ether or whatever, but those components will equal what we consider gravity. So until a more accurate model is found, we'll call it gravity and it'll be an acceleration of 9.80m/s^2 at the sea level.
I can tell you with 100% certainty, that a 32 mile wide thermonuclear reaction 3,000 miles away would destroy the earth, so that is why I don't believe the sun is the size or distance you claim, not because someone told me. If you set up solar panels, you can get an amount of power from them. That power is very closely related to the ~1400w/m^2 that we get from a sun considered 93 million miles away.
My greater point is, if you are going to claim there is no gravity, or that the sun is 3,000 miles away, please explain how that holds true to what we can observe or predict with some sort of consistency. Put the pieces together for us, and if it holds, it holds. Keep in mind, that if you change assumptions about gravity or the distance from the sun, you can't make the same assumptions that the experiments that prove your point still hold true, so make sure you double check that. Describing something as a function of something else that you claim doesn't exist isn't great math. I can claim the earth is a triangle, because you can go up. But until I unify that theory with proof, theres nothing to talk about.
On a side note, I mean, you could wait 10 years until a trip to space costs the same as a plane ticket to observe for yourself. Or just launch your own weather balloon with a camera for a whopping ~$300 cost.
*edit* Sorry, I didn't ask the real question here. So if gravity doesn't exist, what does?
How do you know it's the earth rotation which causes things to fall at that rate? I think we all agree that things fall at 9.81 m/s^2. That's the how. I think the
is being questioned. Is it the spinning earth or something else? I feel like we are getting caught up in the word gravity. The more appropriate question is can it be proven that things are falling at that rate due to earths spin?
I don't think you can just launch a weather balloon to see the curve. I have seen amateur footage that got to 120k feet. The horizon raised to eye level and was flat. I'm fairly certain you would need one hell of an elaborate setup to get to say double that height. I for one would love to see if we could get a balloon up higher than say 300k feet. Not sure if it would be high enough to see the curve or prove shape. I would love to see the proof in this fashion as it would seal the deal for humanity. I'm talking amateur scientists and enthusiasts replicating the experiment 1000's of times over not NASA or a govt space program.
It's the same basic issue with the pressure gradient. We know the pressure is there we can test it. Why is the pressure there? Can we prove it is the earths spin which allows us to have this pressure with no container?
Cool physics teacher and lesson here about air pressure. (ignore the flat earther comments and enjoy the video and science)
