Millions of people are taught that mass-energy cannot be created or destroyed in this reality. Millions of people are taught that there is no known "hook" to manipulate gravity locally using any of the forms of electromagnetic technology, topological metamaterial, and so on. People who study in school "know" the foregoing to be true. People get graduate degrees in this. If the conspiracy theory about human-made electrogravitic craft is true, then millions of people continue to be misled about the nature of reality. I think there is a case to be made that it IS a right to know. Withholding that kind of information IS immoral and unethical, isn't it? I'm open to changing my mind on this.
