Why do they lie about mercury?

Your followers seem to be unaware of the Minamata Convention on Mercury that just about every nation on Earth has signed onto and that will make Mercury unobtainium. There's no denying that there are dangers with Mercury, as with most elements. Elemental Mercury is the least dangerous, but has invisible vapors that are toxic. The vapor issue has been overstated. Inorganic Mercury compounds are usually poisonous or toxic, but we also got by okay with Merthiolate, Mercurochrome, and Calomel for a long, long time. As with most things, a little bit can kill a pathogen but not us, that fine line between poison and medicine. Organic Mercury compounds are the primary concern due to bioaccumulation in lifeforms and some particularly nasty things like dimethylmercury, almost always cited as the case study in why we should ban Mercury due to the death of Karen Wetterhahn in 1997 ten months after absorbing a few drops. This isn't a compound that is common, they specifically synthesized it, and almost nobody will ever encounter it in the wild. There are PLENTY of hazardous elements and molecules and we don't do the kind of ban on those compounds that is being done with Mercury. Because this makes no sense, it suggests another use case for Mercury that has not been disclosed, or is not well known. Mercury will be basically Unobtanium in the USA by 2028.

What did they lie about exacly?

Haven't seen the antigravity on that boring ass video. Is it coming in part 2?

Because it’s the secret of anti-gravity and free energy. The economy would collapse.

One particularly interesting thing I learned about Mercury, which is also true for other heavy elements, is that the inner electron orbitals are moving at relativistic speeds. This affects the melting point of Mercury, and why it is liquid at room STP.

Homopolar motor , like Barlows wheel... they teach this in college. Why do you think they lie about this? It's pretty common knowledge...

Yep this is the path to vertical lift travel. Mercury and Magnets.

Now, how to draw energy from it without getting suicide by politicians and billionaires? Lol
