You mention two very interesting topics in this video: ufos and the power of 9's.

Regarding ufos, I believe the technology is old but just suppressed by non-human forces living below our feet. As Solomon the wise said:

“The thing that hath been, it is that which shall be; and that which is done is that which shall be done: and there is no new thing under the sun.”

Ecclesiastes 1:9

Now, regarding special numbers (e.g. 3, 6, 9) it has to deal with vortex mathematics which is critical for free-energy. The man who knows most about this is Marko Rodin.
