Antigravity aficionados and fans - it isn’t real or possible by everything science knows. You need negative mass to make antigravity apparently but there is no known negative mass in the known universe.
And sure there has been even fairly serious research into antigravity. There was lots of research into transmuting base metals into gold too, but nothing ever came from it. I believe someone demonstrated it by bombarding some nuclei with accelerated particles but the sample was probably very radioactive and cost far more to do than the gold was worth (by a factor of a trillion).
Folks need to have more than hand-wavy conspiracies if they are going to claim these things. Show us the information spirited away in innocuous patents. Provide examples.

Anyone who sees this kind of junk science needs to understand that just because the military and scientists looked into these things out of responsibility to the truth, it doesn’t mean there is anything to it. The military also looked into ESP just in case there was anything to it. Again rejected. It’s what the movie “Men Who Stare At Goats” was based on.
People who push this stuff are playing on ignorance and scientific illiteracy. Don’t fall for it. So much of this junk science is easily disproved. The rest may require things regular people don’t have access to (like particle accelerators) and you have to take science and scientists’ word on it.
The thing is none of this is hidden from the general public. Get a physics degree and you too can understand why this kind of bunkum stinks to high heaven. Because it is bunkum.
