The wiki says that "As it is difficult for proponents of Flat Earth Theory to obtain grant money for scientific research, it is nigh on impossible to determine which of these theories is correct." and then points to the Dark Energy and Davis Plane theories. I was wondering, what experiments or research could we do to try and better understand the Universal Accelerator? Obviously we can't just dig all the way down until we break through, I don't think there's enough grant money in the world for something like that, but what else could be done?
(I'm just wondering if anyone has any hypothetical ideas, I'm not neceessarily looking for anyone to come up with an experiment someone like me could actually do - if your experiment would need the Hadron Collider or something then that's still fine! The wiki implies they might be kind of expensive anyway, and if it was something I could do, someone would've already done it already.)
Although it may seem gravity and universal acceleration can work as substitute for each other, there is one thing that is different about them, which you can use to distinguish them.
According to the theory of gravity, the downward pull we experience daily is simply another one of the attractive forces that exist between objects with mass. In this case the Earth attracts us, and we attract the Earth. However, the Earth is much more massive and therefore it is able to exert a greater force than we can exert on it.
On the other hand, the theory of universal acceleration states that the Earth is accelerating up to catch us giving the illusion of a downwards pull.
The difference is subtle but it is of major significance. Universal acceleration claims that the Earth is accelerating up. This means that the Earth MUST be accelerating up the same amount EVERYWHERE. Otherwise, faster accelerating pieces would fly off. The implication is that you should get the exact same value for the downward pull no matter where on Earth you take the measurement. Gravity, however, does not requires this. Therefore, you can get different values of downward pull at different locations.
The experiment could then be to take careful measurements of the downward pull in different places of the Earth. If the value is not constant, UA fails to explain observed reality. Though we still would not have proved that it is gravity, but whatever it is, it’s not UA.
