Ufology Research

If, as some UFO fans insist, that aliens exist in a "higher dimension" or an "alternate dimension," what does that mean? 

Some UFO fans point to physics papers that postulate eleven dimensions, so there actually may be "higher" dimensions than the usual four dimensions we live in. And that, they say, is where the aliens live. 

But that is mathematically silly, because the eleven dimensions actually apply to everything in THIS universe, and we are only able to perceive four. Has nobody besides me ever read Flatland? (Let alone Sphereland!) I'd like a physicist or mathematician to explain in simple terms why entities cannot exist in only dimensions 5 to 11. In other words, we exist in eleven dimensions, too!

And "higher states of consciousness." Yes, ardent UFO believers accuse skeptics of not understanding the nuances of "new ufology" because they're not as advanced as the true believers, some of whom have received "downloads" from aliens who want them to assist in Disclosure. 

Okay, but don't you mean "awareness" instead of "consciousness?" All beings with sufficient brain size are "conscious." And "consciousness is simply the awareness of one's self. But I think they mean some people have heightened perception and a greater awareness and understanding of humans and society, which is quite different.

And okay, I'm not "vibrating" at the right frequency to see UFOs zipping across the sky, as people who pay money for courses in Monroe meditation or Greer vectoring can do. Isn't that just a faddish recognition of quantum physics, in which we know atoms are constantly in a state of resonance with other atoms? An atom with a slightly shifted frequency (through some undefined mechanism) doesn't just vanish from our universe and appear in a different universe, it ceases being that particular atom and cannot react with other atoms in the same way.

So please, can someone who REALLY knows quantum physics and math please come to the fore?
