US Goverment projects involving alternate dimensions?

Are there any project where the US goverment worked on opening portals to alternate dimensions? I have been wondering if any existed because I watched that stephen king movie called the myst and I heard the C2C frantic caller on youtube and he said some thing about this.

I believe the Philadelphia experiment had something to do with a war ship entering another dimension while experimenting with invisiblity. Apparently men dissapeared, some were embedded in the bulk heads and the ship dissapeared for a period of time and ended up a large distance away.

Something to have a dig at anyway

Try doing a search for:

The Philadelphia Project
The Montauk Project
and Al Bielek

you can also check out the Unified Field Theory but that doesn't really involve the gov't

I think your best starting point as Ozweatherman mentioned would be the Philladelphia Project.
There are a number of interesting theories surrounding it including the possible attendance of the great scientific minds of the day such as Tesla and Einstein.

I think there are a few threads on the Project on ATS so i suggest you do a search and see what comes up.

Keep us posted if you find any other projects involving other dimensions as it is a very interesting subject.
