Aliens and UFOs explained on Google Video

The amount of work NASA does in attempt to find extraterrestrial life is immense. They've had 2 rovers on Mars for what 2 years now? They've been trolling around that planet non-stop in that time and have made some amazing discoveries - some very recently. NASA and the US tax payers are funding the biggest science project in mankind's history - all to find life. At least half a dozen probes are launched every year to go in search of life at other planets.

The thanks they get is few and far between. Then they get people making up crackpot theories that they've already found life and have known about it for years or even decades. Sorry it just grinds my gears a little bit :(

Good post.

And don't forget the billions spent on SETI.
 
I have a feeling that in the next century SETi will pick up an alien signal. However it will only be one way communication, due to the distance between the planet of it's origin. However it would finally confirm to mankind that we are not alone.
 
How far can SETi reach though? Can it listen to our entire solar system? I was under the impression that it can only listen to a very small sphere of space in our galaxy.

We are certainly not alone. Just look at some of the freaks on the interclick. :eek: :D
 
My understanding is that there's no specific limit as long as there isn't something else in the way (e.g. another galaxy or blackhole :p) Once NASA's moon base is up and running in 20 years, SETI reception should become even better as they're already in talks to setup a radio telescope on the dark side of the moon where it's free from all earth interference.

Urm, the "close" stars start from 4 light years away.

thats the closest;) and in terms of distance in space a few 100 light years is nothing saying the our own Milky Way Galaxy is around 100000 light years across
and that is one of around one hundred billion galaxys.

That clip shows an object that appears to change direction. He also points out an object that enters the atmosphere and he calculates that the object is travelling at 900,000 MPH. BUT.. Look closely at the earth's surface and you'll see that the tape has been speeded up and slowed down again. So his calculations are absolutely incorrect, are they not? It's actually travelling a lot slower that that. Can anyone explain why this clip is speeded up at the end? :confused:

look again - the clip isn't speeded up - the camera changes focus and zooms out (you can see the stars get closer together as the camera zooms out).
so the zooming out brings the other objects into the frame (which appear to be moving at gtreat speed because of this but they of course are not) and then once the camera stops zooming it looks like the object changes direction - but it only appears this way because of the zoom out - its been moving slowly in one direction all the time (the zoom out makes the object appear to move towards the center of the lense). the zoom also explains the apparent curve of the other object because its closer to the center of the screen and only moves towards the center a little.

its all very obvious and easily explainable by someone who isn't a grade A moron :p

One of the closest.

That's just 16 light years. Plenty of solar systems there to listen to.

I know 100 light years is nothing in the great scheme of things. But the larger the distance the less chance of receiving a signal. Also, the age of the signal would also be hundreds of years old, meaning a reply from us would take a huge length of time to send, and then again, a possible reply from them even longer.

I always though SETi tried to listen to 'local' solar systems, so that if we did pick up a signal from a planet 8 light years away. Stellar communications between us and the ET's would be of a more tolerable time delay.

Why does that remind me of the Father Ted sketch... Now concentrate this time, ritcH. These are very small; those are far away...

The tether cross-cuts the dust, therefore the dust is behind the tether and you can use the 12 mile long tether to calculate the diameter of the dust to be 2-3 miles long. You are the one that needs to concentrate so nerr nerr nee nerr nerr ;p

On SETI...

The latest info on SETI from Dr. Greer is that one of the top scientists there has received an intelligent single and Greer is in the process of trying to coax him out. Also I don't think SETI is government funded any longer and hasn't been for quite some time - although I haven't checked this out and could be wrong.

I only deleted that because I thought it was too authoritarian to tell people what they can and can't debate. Not because I was being serious. :D

edit: just so this makes sense, I was telling people they shouldn't debate the feasibility of traveling light years because it's impossible to understand. Therefore I suggested we should stick to debating that which we do understand and can "see" on the videos - [sarcasm] human motivation and dust ;p [/sarcasm]

sure theres lots of life out there. HAS to be, but 99.9% are probably like us who have only travelled about the distance of a grain of sand in terms of space travel.
 
So johnny do you therefore believe that it is possible that, the 0.1% which has mastered galactic travel could have visited Earth?
 
I guess it is possible, but I don't believe it is feasible.

Perhaps somewhere out there, two civilisations have met, due to being within a few light years of each other.

Maybe the human race is simply to far away from it's nearest neighbour to ever make contact. :(
