Aliens....!
« on: August 30, 2016, 11:04:16 AM »
Hi everyone,

Aliens could be contacting us....! Really. 

http://edition.cnn.com/2016/08/30/health/seti-signal-hd-164595-alien-civilization/index.html

***********

Astronomers engaged in the search for extraterrestrial intelligence (SETI) are training their instruments on a star around 94 light years from Earth after a very strong signal was detected by a Russian telescope.

"The signal from HD 164595 is intriguing, because it comes from the vicinity of a sun-like star, and if it's artificial, its strength is great enough that it was clearly made by a civilization with capabilities beyond those of humankind," astronomer Douglas Vakoch, president of METI International, which searches for life beyond Earth, tells CNN.

Whenever a strong signal is detected, "it's a good possibility for some nearby civilization to be detected," Maccone tells CNN.

Paul Gilster of the Tau Zero Foundation, which conducts interstellar research, said that if the signal was artificial, its strength suggested it would have to come from a civilization more advanced than our own.

Such a civilization would likely be Type II on the Kardashev scale, an attempt by the Soviet astronomer of the same name to categorize various technological stages of civilizations.

***********

Of course it could just be a supernova or something.... We have had such false alarms before.  :)

Cheers.

Sriram

Just as it would be surprising if Earth was the only planet in the universe to host intelligent life forms, it would be also surprising if aliens weren't trying to explore their bit of space for signs of life.

True, so very true, wait for it, wait for it!!!......................this Universe is so finely tuned to make life possible, why is that, why Floo!! "WHY".

Old Blue will be along in a minute to tell us all about about multiverses and that we are just lucky enough to exist in this one life giving Universe, I am a puddle which just happens to fit, a thinking puddle :o :o

It doesn't look finely tuned to me. Most of what we can see of the Universe is completely inhospitable to life of any sort.

I still don't get the fine tuning argument. Yes life exists, yes some small changes might mean it didn't but there is a leap to what exists is the purpose that I don't think can be made.

And even if we ask the why, how do we get to any answer. If you answer it with a who or even a what you end up with an infinite regress.

Dear Jeremyp,

Most of!! most of!! We are a tiny speck in something we can't even imagine, its vastness is.................... well actually I don't have a word to describe its vastness, how about "mind blowingly unimaginable".

So it would be strange if other tiny specks in the vast universe of ours didn't have the right conditions to produce life forms like us, imo.

The signals were emanating from an old Soviet military satellite....!   These astronomers, I tell ya!

It's not finely tuned for life at all.

You exist on a very thin layer on our planet.

How well would you do on Mars, or Venus or in the vast space between?

The universe is tuned to kill you, and it will succeed.

And that is the point. Any tiny event can wipe out all life on earth. But life has survived for 3 billion years and evolved to be so complex and  intelligent.  If the probability of humans evolving is calculated, it would be Zero.....but here we are!

Why would it be zero?

This is just the lottery winner syndrome.

Something (ANYTHING) that gains enough intelligence to think "I am here, what are the odds?"

Given the size and opportunities in the universe (which we don't know) why would the odds be low, and not high at some point?

The lottery example is nonsense. A lottery is declared and someone WILL win. There is no doubt about that. Who will win is the only doubt.

Life has not been declared by anyone.

A video on the probability of a single protein forming by chance....forget about complex life evolving.

Wot Sriram just said but with finely tuned bells on ;)

A very human reply, a bit like Jeremyp's reply of "most of what we see" Mars, Venus, the bits we see, who knows what is happening in the great vastness of our/this Universe.

No you are wrong.

If no life exists then the question does not arise.

Only if and when it does exist could those creatures say "Hey this universe is designed for me", and they would be wrong.

In every other universe where no life of any sort is possible, what do the creatures there think?

Dear Berational,

I don't say

  "Hey this universe is designed for me"

I say this Universe is designed for, set up for, or rather those pesky scientists say,

seem to be finely adjusted
or

initial state of the Universe must have been carefully chosen

For life.

This Universe brought forth life, we don't have any other Universes to compare.

But any universe that just happens to also have life will have those creatures thinking "this was setup for me".

It may not have been that way, and was just luck. Universes that do not support life do not have creatures saying "this universe was not setup for me"

So your observation is just a silly truism.

Life evolved to fit the circumstances, (the so called Goldilocks zone), that are available here on earth.

You still haven't got a grasp on how evolution works Gonners?

Intelligent life from elementary particles is fantastically rare, but also space and time are mind-numbingly huge.  Maybe there is a simple probabilistic relationship there of the form, complexity varies inversely with the size of spacetime. Or put another way, the size of spacetime limits the maximum complexity it contains. It seems that intelligent life is an inevitable outcome of the natural laws of this cosmos and its rarity is also the measure of its complexity.

I've yet to make my statement to the world, I'll keep you posted Floo.

Let's hope Star Trek lives forever.
