Well friends you must have heard about UFO's and lots of research are being going on this to find the real fact.
So, what do you think about it?
Do you know the technology a race would have to possess to attain galactic/intergalactic travel? It isn't what you see on TV or the movies. If they would ever arrive at our planet there would be no mystery, it would be spectacular and obvious imo. Each and every serious ufo investigation is easily explained and has never been aliens. I'm of the mind it's highly improbable that we are the only life in this universe, but they haven't been here...
It would be spectacular and obvious if they used a reaction drive. But the energetics of reaction drives are awful. The best example, a photon drive, needs energy of mc² in order to produce impulse of mc, meaning that you need c times as much energy as you're actually giving the ship. A photon drive consumes 300 megawatts for every newton of thrust! Imo that is one of the best arguments that nobody's using photon drives; they'd be detectable at cosmological distances.
So we are almost forced to assume that interstellar travel will use a nonreaction drive ... or be in slowboats running at perhaps a few thousand km/sec. The energetics of a diametric (polarized gravity) drive reduce to the energy needed to shift the ship. The philosophical quirk here is that it takes 21x the energy to get from 10km/s to 11 km/s than it takes to go from standstill to 1 km/s. Against which reference frame is a diametric drive acting? cn
agreed most theorys on intergalactic space travel use massive amounts of energy thats would be obvious detectable, even with out meager technology.
even an antimatter drive that uses antigravity to shoot form star to star could be detected by our tech.
UFO = unidentified flying object
It's the things that I can't see that I don't believe in.
No i dont believe in UFO.I think it just a human tendency to research if there is more people talking about particular thing.Now a days people are talking about nanotechnology but still we dont have any practice example of that.
Does anyone care to discuss or explain why religious paintings as far back as the 12th century depict "ufos". In some cases even further back, also there are hundreds if not thousands of artworks in stone depicting alien beings and craft, am I to believe that the conspiracy has been afloat for so long?
