There is such a possibility:Alien people’s culture are different from ours.Maybe they are finding us in another way,but we don't know...

Who knows what technology they might have. Far beyond our imagination.

Maybe so but presumably still within the laws of physics as we know them.... unless different parts of the universe have different physics? For any sort of long distance space travel to even the nearest star to be a practical possibility, we have to go faster than the speed of light. But we are told that it cannot be done, because at that speed mass becomes infinite.

If there are aliens they could well be within our own solar system. Who knows whether there is a giant planet out there 10 times further than Pluto?

That we do know. The planets orbit where they should.

That far from the sun those would be icy aliens. Hey, maybe that is the home of the Abominable Snowman?

I was under the impression that we still struggle to define all the laws of physics in the known universe let alone the others which may (or may not) be a sneeze away.

Even when we 'know' everything about our physical universe we will then have to devise ways of using that knowledge. That could take a while.

I accept that SETI may be a waste of time. 'They' may not want us to know they are there. I do it simply because I am curious.

Mind you, I am also an artist so I can make it all up as I go along anyway!

I think it's nearly impossible for them to hide. Because every lifeform leaves footprints. If they are intelligent they must use a kind of information transfer, and now/ or in the future we are/ or will be able to detect them.

Au contraire, mon frère! The moon is positively littered with spacecraft: 26 (so far). Indeed, six of them were piloted by intelligent beings.

Of course, they are all of terrestrial origin: http://en.wikipedia.org/wiki/List_of_lunar_probes

If you are interested to look at them, you can see the images taken by the Lunar Reconnaissance Orbiter (LRO) at moonzoo.org.

Well when Neil put his foot down, it was the only footprint on the moon, but that only lasted a few minutes.

I think Monty Python said it best:

"So remember, when you're feeling very small and insecure,
How amazingly unlikely is your birth,
And pray that there's intelligent life somewhere up in space,
'Cause there's bugger all down here on Earth. "

Would be nice to see this one day where credit was shared...

"I am delighted to announce that SETI@Home has discovered a tenth new radio galactic communications emitter in data. Acquired long ago the tapes containing the data were analyzed utilizing FFT's and Signals analysis for advanced communications concepts including Pulse Amplitude, Pulse Position, Pulse Phase and other techniques far more revealing than previous software.

Further details about the newly-discovered emitters can be found on this web page, and will be published in due course. We are in the process of contacting the volunteers whose computers found this alien group of emitters, and will post information about them in the coming few days.

Located over XX light years from Earth it is anticipated that these emissions represent something so far back in time as to be absent from the present day universe in a form we would comprehend.

Thank you for contributing to SETI@Home"


We can but hope...

Goodbye Steve!

I see the thread is a bit old now but I have two questions if anyone is still out there.

1) Why was Pangaea all scrunched up on one side anyway?

I assumed it would be strung out symmetrical about the earth if it had been there for billions of years. Had it drifted back together after a previous separation or is it the remnants of a collision with another body?

2) As we are looking for signals from other life forms, have we actually ever sent any deliberate signals out (other than Carl Sagan's Gold disc)?

With apparently, some of our less passive brethren intent on war with Iran, perhaps we should send out an SOS? Or is that a bad idea as well as too late?

Actually more than a couple of questions.

I think a case can also be made for Douglas Adams:

There is a theory which states that if ever anyone discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable.
There is another theory which states that this has already happened.

50 years of SETI - no signs of life out there. What a waste of time.

SETI observes an extremely small part of the radio spectrum in some of the sky. I'm afraid your statement is quite premature.

The continents are not very symmetrical now (mostly in the Northern Hemisphere), so why would they ever be symmetrical? We see some pretty non-symmetrical features on other planets in the solar system as well. Some of those were caused by collisions, so your question about collision with another body may be very relevant.

I believe Pangaea is a hypothesis that says the continents we see today were once joined. It doesn't say anything about other continents that may have come and gone in the mean time. In other words, who knows what the parts of the planet that were not Pangaea looked like back then?

The variations in height that produce continents and oceans are very very small, when viewed on a global scale. The existence of dry land at all is just random scatter in the data. Looking out my window on a rainy November day in the Northern Hemisphere I could almost believe dry land is a myth.
