Jack I think you have seen me list some of my background; if not, I can let you know privately.
Some of us who have been in academia, understand full well what is going on (as well as the ability to vindicate our own math and science), and are not afraid of public opinion or lack of grant money. Some of us, even, choose not to contribute to academia, as it were, because of its history and attitude on modernity and the future.
With that said, the ancients knew the reality of our realm; it isn't new information. People know - both learned and layperson. Most people are just told they do not know, and they believe it.
Neil Tyson may be the spokesperson for modern academia - I wouldn't use "spokesperson," but whatever works for the paradigm. I have the work to prove gravity is electromagnetic in nature next to me (in fact). I would never send it for academic peer review. I am not an anomaly in this context.
The other part of the answer is that academia gets more grant money for innovations that use current energy technologies - not for rewriting the foundations of science (as it were). So, even if gravity is known by academics to be electromagnetic in nature, it won't come out until money can be made from it - since the private grant money comes from someone who is likely a capitalist. Fundamentally redefining science means redefining industry - which is why Tesla was swindled into bankruptcy, and his work stolen.
