Astronomers search 100,000 galaxies for life, and they find ...

NO SIGNS OF LIFE!

I urge you to read one or all of the above links, but I'll give cliffs anyways:

1). "Whether an advanced spacefaring civilization uses the large amounts of energy from its galaxy's stars to power computers, space flight, communication, or something we can't yet imagine, fundamental thermodynamics tells us that this energy must be radiated away as heat in the mid-infrared wavelengths"

2). NASA’s Wide-field Infrared Survey Explorer (WISE) completed a 100,000-galaxy search for objects consistent with galaxies emitting too much mid-infrared radiation emissions.

3). The astronomers have carefully examined the data, and they find no signs.

Possible answers

1) There is no alien life in the 100,000 galaxies, but there may be life elsewhere (Still, how does 100,000 galaxies end up empty?).
2) The fundamental law of thermodynamics is wrong (we just don't know it yet). The aliens are using stuff that doesn't release mid-infrared radiation.
3) The aliens are so unlike us that they, for some odd reason, don't colonize outer space. Somehow, they have stopped all technological developments. Somehow, they have stopped all ambition to explore. Somehow, they have stopped population growth problems and have remained on the resources of one planet for billions of years.

OR

4). There are no aliens.

100,000? Come back to me with a reasonable relative sample size.

100,000,000,000++++++




think for a second how long the human race has been "observable"

less than 200 years.

now look at the age of the universe

over 13,800,000,000 years.



We could exterminate ourselves at any moment, leaving an inconceivably small window of time in which the life on this planet could be observed from such a great distance. Logically the same would be true of other "sentient" lifeforms. It's like looking for a needle in an infinite haystack and you only have a fraction of a second to search

[jmonty]

I thought organic molecules were detected recently.

[xXGHOST23Xx]

100 000 lol. That's like searching 1 street

[TimSoda]

i hope im still alive for when humans come in contact with aliens.

Yes, 100,000 galaxies is small compared to the rest. But still, 100,000 galaxies is a lot! As of now, we're 1 out 100,000 galaxies!

How is it possible? The conclusion, I think, is that life is something special and distinctive.

[jmonty]

We don't even really know wtf is going on in our own solar system and have barely sent probes to Mars.

[bruverend]

orrrrrrrrrrrrrrr what if said aliens have a blocker so they cannot be detected via radiated heat.

[jmonty]

Maybe they're smart enough to remain undetected...

5. We are the most advanced civilisation in the universe.

Not as improbable as you may think, I am sure there is alien life but intelligence is something else.

[AbbeBusoni]

The fundamental law of thermodynamics says that they would be easily detectable. See this quote:

"Whether an advanced spacefaring civilization uses the large amounts of energy from its galaxy's stars to power computers, space flight, communication, or something we can't yet imagine, fundamental thermodynamics tells us that this energy must be radiated away as heat in the mid-infrared wavelengths," Wright said. "This same basic physics causes your computer to radiate heat while it is turned on."


You could suppose the fundamental laws of thermodynamics that we know is wrong, but that is just that --- a supposition.

[Aynom]

implying aliens must be hyperintelligent.

Science Fiction of peace.

For all we know, we could actually be the most advanced/intelligent life in the entire universe, which would explain why we have zero point of reference for anything bigger than us and we have all these knee-jerk unanswerable questions.


It's mere speculation. You have to literally reach for the stars to make a judgement call on life or no life lol.

on point, they were looking for intelligent civilizations not just life.
secondly, there's places so far away from us that their electromagnetic radiation hasn't even reached us yet

[T0rtilla]

Bro.. did you read the articles? Those scientists were looking for "advanced life" (i.e. far smarter than humans), not just regular organisms like us. There's probly tons of organisms similar what you'd find on earth out of those 100k galaxies

[butwhowasfeel]

masha'allah

Good point --- I probably should have worded the OP to say advanced civilizations, not life. There may still be bacteria, plants, or animals in these 100,000 galaxies; but there are no intelligent civilizations.

[T150]

100,000?

That's like looking under a paving stone in the front yard.

[HMFIC_BROWSIN]

If you really think about it:

-Advanced human civilization is extremely young currently. We are a fart particle in the history of just earth
-Relative to all other galaxies, even if advanced beings did exist, they likely died by now.
-If the beings become advanced enough to create AI, AI likely would eliminate the advanced species and cover it's tracks so no one could find them.



also, the fact our planet formed the perfect distance from the sun, correct size, correct elements, etc etc etc is similar to hitting the powerball 5 times in one human lifetime.

[schlitta]

I believe that we are not the first life (in terms of Earth) to ever exist in the universe. I think it is likely we may be the only ones living right now. In other words, life may have existed elsewhere before us and died off, and there may be life after us

[Bar182]

100,000?

That's like looking under a paving stone in the front yard.

Hardly.

100k Galaxies. Galaxies.

That is a lot of real estate.

that's a fallacious argument

we've "searched" less than .01% of the observable universe. the observable universe in all likelihood being the a tiny fraction of what's really out there.

and this "search" is in no way exhaustive. it does not prove that (1) there wasn't previously sentient life there (2) there isn't currently sentient life there, or (3) that there won't be sentient life there. it only proves that during a tiny period of time there was no evidence of sentient life being broadcasted

Please read about the "Drake Equation"

[superfunk]

Maybe actual intelligent life is efficient and doesn't waste precious energy as heat? Crazy idea i know...

[T150]

Hardly.

100k Galaxies. Galaxies.

That is a lot of real estate.

Was being semi-srs, but in a number of at least 100 billion, it's not so far fetched. 100k is a drop in the ocean.

And how many advanced civilizations would you find in a drop of our water? You'd find life for sure (but dat ain't the point).
