this world Ufos aliens all come from different dimensions were not so advanced as then though
The existence of aliens would not prove the existence of parallel dimensions.
Regarding the article, this is so full of BS. I made a little research, and here's what I found:
The oceanograph Dr. Meyer verlag, apparently discoverer of those pyramids in 2012 (which appeared as discoveries in newspapers as early as 1991 already) , does not exist. There is no Dr. Meyer verlag, oceanograph, in the internet. Same with the one who supposedly found a crystal ball in one of those pyramids in 1967, Dr. Ray Brown. [url=http://perdurabo10.tripod.com/galleryg/id104.html]There is no trace of him or of that sphere. The articles also mention U.S. and French teams who apparently independently confirmed those discoveries, but those teams are specified nowhere. They probably don't exist either.
As for sources, the link at the end of your article leads to only more articles, and most of those links lead to the conspiracy site BeforeItsNews, which doesn't give any sources. Other link threads end up at a site of a paranormal investigation team founded by Zach Royer, but none of his team has any qualification except being interested in paranormal and esotheric stuff.
The journalists that wrote the article in the local Florida newspaper are said to have lots of data, diagrams and photographies, but nothing is shown or linked in the article.
As for the thing with the Kirlian photography and the energy thing, it leads to some shady sites mentioning a Vanguard Science group doing "alternative science". Do I need to tell what's wrong with that?
Also, those images definitely look photoshopped. Don't forget that at 2000m, virtually no sunlight comes through.
As for the realism of this story, the fictive Dr. Ray Brown tells of having found the ball in one of the pyramids during a dive excursion with friends. The fictive Dr. Meyer Verlag found those pyramids at 2000m depth. Even if, as said so in the article, they are 3 times as big as the Cheops pyramid, the uppermost tip would still be far below 1000m depth. I don't know of any human that dives that low.
Of course there is. Both science and spiritual / religious beliefs say this. And it would be impossible for there to be one dimension. All 4 states of matter can be shifted and perceived in different ways. So yes there is more then one dimension.
I hope you're meaning dimensions as in time, space etc., not as in parallel dimensions.
