Ancient Astronauts

The capitalist class has hidden the truth about aliens, like how ancient peoples were visited by them.

[Revy]

Well yeah. the evidence is staring us in the face. When astronauts even come out and say they've seen UFO's. there's a lot of art from ancient cultures which shows beings similar to the "Greys" in appearance. There's also a lot of UFO's that can be found in Renaissance era paintings.

It could also be ancient glamrockers.

Why would capitalists conspire to cover up the existence of aliens?

Sounds like a crazy conspiracy theory!

I saw a black disc on the sky. So awesome!

More seriously, while I do not doubt that there is intelligent extraterrestrial life somewhere in the vast infinity of space, it seems unlikely that the ruling class would cover up their existence. If anything, they would publicize and demonize them so as to create a universal boogeyman to use to keep the workers in check.

Although, I suppose they already use communism to serve that purpose...

Were we to be visited by aliens, they wouldn't come in dinky little saucers. Something capable of crossing interstellar space would be many kilometres in size.

I don't quite understand the logic in that. What does the size of the ship have to do with anything? We don't know how interstellar space travel would work (it is reasonable to conclude that if they have visited us, they have found a way to get past the speed of light, whatever that would be.)

Though, certainly, there could be a huge "mothership" where all the "scout" ships come from.

The common theory is also that they do not "fly" like planes do, driven by propulsion, but rather some form of electromagnetic levitation (anti-gravity). This would explain why hovering UFO's near the ground have always been said to interfere with electronics (because of the EMP).

X-files anyone?

i know Neil Armstrong is getting on a bit, but calling him ancient is just rude :D

[Killfacer]

I think the flood are about to kill us.

Fuel capacity. Even with the densest fuel type that is known to physics (a neutronium/anti-neutronium mix), you'll need a hell of a lot of it to get from one star to the other, at least in a reasonable amount of time.


We don't know how interstellar space travel would work (it is reasonable to conclude that if they have visited us, they have found a way to get past the speed of light, whatever that would be.)How is that a reasonable conclusion? Hibernation/stasis, long lives and a lot of patience, robotics, and generation ships are far more plausible because they don't involve buggering relativity sideways.


Though, certainly, there could be a huge "mothership" where all the "scout" ships come from. That just moves the problem elsewhere. An engine or cluster of same capable of crossing interstellar distances would be very bright and noticeable, as well as having a distinct spectrographic "signature" meaning that it would be unlikely to be mistaken for something else.


The common theory is also that they do not "fly" like planes do, driven by propulsion, but rather some form of electromagnetic levitation (anti-gravity).Electromagnetic levitation is not the same thing as anti-gravity.


This would explain why hovering UFO's near the ground have always been said to interfere with electronics (because of the EMP).But such a propulsion system would be useless for crossing interstellar distances, since electromagnetism obeys the inverse-square law.

Lol, I really didn't want to get caught up in this conversation, but I don't believe we have been visited by aliens..

Although, if i were to speculate on interstellar space travel, I would say that they would bend space so they wouldn't have to travel such a vast distance.

Something like this maybe?


Lol, reminds me when I was 12 I use to watch a lot of tv (like x-files) and i imagined that aliens were humans that evolved and traveled back in time to observe history and that because they were living in space for so long and relied on technology, they developed such frail bodies.. - heh, don't let your kids watch too much tv :lol:

Anyhow, I think it's safe to say that we haven't been visited by extraterrestrial life..

I praise your confidence in Stencil's knowledge of physics..

- No offense stencil ;)

Well that graph cleared alot up for me. :blink:

[NecroCommie]

Bah! Of all the fictional would be space travel techniques, the warp travel is the coolest. It does not move the spaceship forwards, but moves the space around the spaceship backwards. Thusly ignoring the negative effects of FTL-travel because the ship does not move technically. :cool: Granted, such a drive would require the energy of several thousand stars, but on the other hand our extraplanar friends have no doubt solved this problem.

[ÑóẊîöʼn]

Wormholes are somewhat plausible, apart from the fact that they require "negative energy" - which so far hasn't been proven to exist. You'll also need a heck of a lot of it; I'm thinking you'll need to be able to build a Dyson Swarm or two, or unlock the energy potential of a gas giant or something along those lines.

Also, if I remember correctly, warp drives require negative energy as well.

Aye it does... would... something...

Wormholes are more tricky in the practical sense I think. The space and therefore your existence would be... well, quite dense in a manner of speaking, and everything material would surely be crushed out of shape. Some scientists believe that this might have negative effects on the human body. In order to pass through a wormhole intact you would have to go through the wormhole in information. You would be disassembled to atoms, and your atoms' places would be sent to the other side in a beam of data. Then some pre-sent machine on the otherside would reassemble you and your ship around you, and you would be off to explore.

But then again, if such teleportation would be possible, it would make sense to just skip the whole wormhole thingy and travel as a beam of data.

This is ofcourse, if negative energy is ever found.

Really? I've heard otherwise - that a trip through a hypothetical wormhole could be undertaken by a spacecraft as primitive as a Apollo Command/Service Module (http://en.wikipedia.org/wiki/Apollo_Command/Service_Module) - the reason being that the negative energy in the throat of the wormhole stabilises spacetime sufficiently.

Of course, if you strike the "sides" of the wormhole you're pretty much a goner. So - drive carefully!

The world's much smaller than they want you to know. You can walk to Moscow in half an hour!
