I don't want to sound like a conspiracy nut or anything, I try to avoid conversation about aliens and ufo coverups, etc. It just seems a bit odd that our space vehicles are still rockets and arent changing much...maybe this just a lack of newer technologies or the cost. However you'd think with all the new theories of antigraivty, electromagnetism, etc that we'd be at least attempting to create some of these devices/vehicles. So I'm just wondering if we (any country) are doing research in secret, specifically on space travel/vehicles. Not that I care to know exactly what it is, just that's it's going on. Thoughts and opinions are all welcome. Thanks.
