Why finding alien life in Universe is now 'only a matter of time'

Methane is inert to silicon atoms unless there is photochemical excitation (electron excitation from light) that creates a "methylsilylene polymer." That might make a great battery but unlikely life.

Note also that there is only about 1,000th of the sunlight received by Earth that reaches Neptune. 

Gosh.  Such specificity. 

 

Perhaps it's silicon and liquid ammonia, or any other combination that's reactive at high or low temperatures, outside the Goldilocks zone.

Like up until they were able to get down there, they thought there was no life on the deep sea floor.  And didn't realize there were organisms spanning acres and acres, but underground.

Tens of thousands or perhaps a million years from now after when we have poisoned our planet and died out as a species, and then after hundreds of millions of years the earth will have buried the detritus of human existence and there will be no trace of us. 

 

Alls well that ends well.

There’s no doubt it anymore. The American government has admitted not that long ago, couple of years at best, that there’s flying objects on earth that can do maneuvers that are simply impossible for anything man made. They even released radar, infrared and video footage of them. The French and the UK government have released information as well. 
 

The only thing I wanna know is how they found us, given the size of the universe and how tiny our planet is. The odds are way worse than finding a needle in a haystack. 
 

There’s several Joe Rogan episodes that deal with the subject matter. It’s quite interesting actually. The ones that stood out the most for me are the one with a navy pilot called David Fravor and the Bob Lazar episode.

More chance of silicon and ice cream.

Neptune has solid and gaseous ammonia (combined in clouds of hydrogen sulfide) than naturally-occurring liquid ammonia (which goes directly from ice state to gas). Silicon can combine with ammonia molecules AS silicon dioxide. But the lack of free oxygen molecules will defeat such a chemical reaction.

So, I take it that you're a Carbon Chauvinist?

I have no doubt that we have been visited by aliens from another world but they took one look at us and said F/that they can't get on with themselves what chance have we got.

 

There is also the Fermi Paradox which first came to light in the 1950's, well worth a read.

 

My favourite theory is whenever a civilisation has evolved enough for space travel they have exhausted the planets resources before conquering the technology required or they simply fight among themselves until they collapse out of existence.

Yes , there is / was / will be intelligent life forms on other planets in the universe .

Will we ( our species ) , ever establish contact to an intelligent alien life form ...?

Probably not . But if so , the aliens will be intelligent machines . AI .

The distances to travel are simply much too big for biological life forms to survive .

There is a reason that direct interaction with alien life forms will not be possible . Apart from the enormous distance that separates us .

 

We are the only dominant intelligent species on this planet .

There will be no second earth to colonize after we destroyed this planet  .

We need to prove that we ( as a species ) , can act responsible enough to our planet that we enable our own survival as a species in a functional biosphere .

But it is late for that by now ... much damage has been done already .

Need to act now , later is too late .

Too many polluting people ... industrialisation and the related pollution by burning fossil fuels  has totally transfomed the world within just 150 years . ( What , geologically seen , is just a second for an already 4,3  billion years old planet ) .

But anyway , if our species fails to prove that we are capable to preserve the life enabling balance in our ecosystems and biosphere , we will just disappear and the planet will rebalance it self in time , or look like Mars . No life .

It is just a test that we need to pass here ...

I we fail any possibility of further evolution for mankind will become non existant  just as we slowly disappear and suffer  in a world where the natural balance is gone .

But somewhere else , dominant species on other planets will pass this test and further evolve . and live .

Up to us ...

If you go down that rabbithole far enough, you'll find guys that are convinced this isn't the first iteration for earth. 

 

They claim it's been decimated by its previous inhabitants, and intelligent life has re-spawned (for lack of a better word).  Maybe more than once.

If you only investigate things you THINK will make a difference history tells you you'd have missed out on some major discoveries. How can you judge now what might be useful in the future? Quantum mechanics would have been classified as that but look at an article in today's Times for an understanding of what that's leading to. 

There was a bloke in a cave who once said why are you bothering to go much further than your immediate surroundings...?

There are things that make my life better, and things that don't. If it doesn't make my life better, why should I care if it didn't happen?

I agree with some of that, but I have a problem with intelligent life has re-spawned as intelligent life wouldn't destroy it's own environment.

I think the point (probably amongst much else) has gone over your head. GPS navigation and satellite communications? No one envisaged that when first venturing into space . I’ll leave you to your lowly ambitions

Or maybe scientists understand that there's not a lot of chemistry going on when the temperature is about 60  degrees Kelvin.

There goes the atmosphere.

Astronomy is all "pure science" without any practical implications.

Voyager1 travels for 46 years now and has reached a distance less than one light day (24 billion km; 15 billion mi).

It will  exhaust it's last bit of energy in two years or so.

It's expected to travel 40000 years until passing another star which is 17.1 lights years from earth at a distance of 1.6 light years.

 

And they are writing about primitive life 125 light years away.

Until super warp is invented it's all a nice past time.

 

Never fear, once the Enterprise has had its 10 billion light year service and respray at the Federation garage, Scotty says we'll be good to go.

Well its about 4.5 billion years before the sun totally consumes our rock but it will burn up long before that .

Optimists (Drake, Sagan) yes, pessimists (Fermi) no, historicists oo'er. The only inevitability I believe in is the speed of light being constant.

What's your point?

The stratosphere is the coldest part of the atmosphere. At its coldest, it's about 190 degrees Kelvin. That's a far cry from 60 degrees Kelvin.

There is a fundamental difference between "discovering alien life" and doing some local space exploration, but I guess that has gone over your head.

 

BTW, only an idiot, IMO, would claim that we are the only planet in the universe with life forms on it. So, they are trying to prove what is already blindingly obvious.

Never mind, as they have to come up with something to get funding for their lifestyle.

Don't Panic, The Vogon constructor fleet, will be here soon.

Drink up,  the worlds about to end.

Loved that series.

I especially loved his solution to government bureaucrats.

Could you please share with us the information you clearly have about "their lifestyle." And while you're at it, some actual evidence of what motivates them?

This narrow-angle color image of the Earth, dubbed 'Pale Blue Dot'.  Taken by Voyager 1 distance of more than 4 billion miles from Earth.

From this distant vantage point, the Earth might not seem of any particular interest. But for us, it's different. Consider again that dot. That's here, that's home, that's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there on the mote of dust suspended in a sunbeam.

Not only is our Earth small in the vastness of the whole Universe, the area we can inhabit on the Earth makes our very existence very vulnerable. 

 

We can only exist in the narrow band of atmosphere that surrounds the Earth. We cannot exist under water or higher than a few thousand feet in the air.

 

And what are we doing with this tiny, tiny fraction of livable space? Fighting and destroying our very existence.

 

I sincerely hope the human race becomes extinct before we have the technology and the means to poison other worlds with our "lifeform"

:sad:

What you want us all dead.

Dear oh dear.

You need a fist full of Viagra, and an afternoon down soi 6. 

Your be fine after that.
