Depends on the "conspiracy" theory you want to explore.

Someone was talking about hyperborea the other day in r/conspiracy, you see the idea come up every few years.

Or if you wanna go down the mackinnon rabbit hole.

Basically something like the later seasons of stargate where the american government has a ship capable of faster than light speeds. Hard to say. I want to believe, and hell growing up near wright pat, ive seen some weird stuff. Including some kind of huge aerial ship, or something being airlifted by like 20 helicopters rofl. Ive told this story before, but whatever it was beamed me with a spotlight and had my cousin not been in the car scared out of his wits I would think I had dreamed it.

I was certainly left with the impression it was man made, it sounded/felt like a freight train running over my head. :shrugs:

I dont think its real, but its certainly possible. There is enough money missing from the pentagons budget we could have several moon/mars/space colonies.

Also, does anyone remember one of the users here showing a old map, which showed australia as being bigger?

Came across this article this week. But I havent seen anyone really talking about it.

Wrong side, but I still think its possible it happened to the other side as well. All the land masses were prolly substantially bigger 10,000 years ago.
