We actually had a civil discussion last time Veeky Forums
Well do you think we are truly alone in the universe or are the odds in favor of some other species all alone out there in space
Let's assume there's life on Pluto we'd have no way of knowing if they were trying to reach us until we were on planet
Do you think Earth would befit from first contact?
Meh this has been done to death...
YES "Aliens" are likely to exist elsewehere in the universe because it's fucking huge
NO we will never make contact with these "Aliens" because everything is really far away and we haven't invented warp drives
NO they won't be little green men, but more likely just bacteria and germs. They won't be intelligent like humans because it took billions of years for us to evolve from bacteria, and we will only inhabit Earth for a small fraction of this
No, there isn't life out there besides us.
There is literally no precedent for it. Until we find life anywhere else, we just have to accept the most likely scenario and the only scenario that there is any actual evidence for, and that is that Earth is the only place with life.
Theres probably other life in the milky way, theres probably older life in parts of the unigerse that cooled before our part of the universe, theres probably not extremely technologically advanced life elsewhere in the milky way, perhaps there is a handful of sentient, intelligent life per galaxy, but it would take tens of thousands to millions of years to contact another one of these lifeforms.
who knows what they could look like, they could look like slugs, lizards, insects, foxes or even exactly like humans if they evolved from apes
i think there's no answer to this question for now until we manage to travel very easily around star systems
>at least 1,000,000,000,000,000,000,000,000 planets in the universe, probably more
You might think you're such a special snowflake but don't state your incorrect opinions as fact. You butchered the definition of 'most likely'.
Oxygen and carbon are the third and fourth most abundant elements in the observable universe. Life isnt composed of some exotic element, life is composed of fairly common elements. All planets had a cooling phase after their formation where common elements coalesced into molecules. Its entirely unreasonable to assert that there factually is life elsewhere in the universe, but equally unreasonable to assert there isnt. Theres a significant amount of information that supports the trivial creation of amino acids is fairly common on planets. Meteorites have been found to contain nearly 90 amino acids, and comets can contain a large number of complex carbon molecules. Its logical to conclude that it is highly probable that life exists elsewhere in the universe, in the same way we can conclude that it is highly probable life formed naturally on earth.
Due to the problem of abiogenesis, I find it highly unlikely.
We can't make a reasonable guess because we have absolutely no idea how life first came into existence. It could be a relatively common phenomenon, or it could be so incredibly rare that the chances of it happening twice, even in a universe as mindbogglingly huge as ours, would be next to none.
Or it could be that life is the result of a higher power intervening in the course of events, which seems pretty likely when you study biology for a bit. To think that this level of complexity and precision just happened because of random mutations and natural selection is too far-fetched imho.
how likely is it that goku is on a distant planet waiting to save our world?
Superman is a more """realistic""" expectation
>Well do you think we are truly alone in the universe or are the odds in favor of some other species all alone out there in space
Absolutely no data no which to base even a rough guess. I'd like to think there are, but we have no clue, and wishing won't make it so. We know there are lots of "Goldilocks" planets out there, but we have zero idea of the liklihood that life will arise on a planet where it could possibly arise. If the nuber of planets was, let's say, 10, and the chances are one in ten that life would arise, then there would likely be somebody else. If the chances were 1 in a million, then probably not. The number of planets out there is X -- a very high number. So with decent odds at all, there are lots of life-bearing worlds out there. But, we do not have any clue what those odds are. what if they are 1 in a-million-times-X? 1 in a-billion-times-X?
We don't know, we have no clue, so saying it is "likely" or "unlikely" is just guessing.
>Let's assume there's life on Pluto we'd have no way of knowing if they were trying to reach us until we were on planet
That is nonsensical. We might get a radio signal, we might see signs of them when a probe flies by, we might see the light show when they fight a nuclear war, they might come to us.
>Do you think Earth would befit from first contact?
Unlikely, assuming first contact is when somebody comes to us -- the low man on the totem pole has not fared well in history when two cultures meet. Intent of the more advanced society has not mattered much; it turns out badly for the less developed. If it's just a case of we intercept a signal and know they are there, it is less likely to be a disaster, but not likely to really change much. We'll be excited for a time, but it won't change much here.
>>at least 1,000,000,000,000,000,000,000,000 planets in the universe, probably more
What if the odds that life will arise on a given planet are 1 chance in 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000?
>Or it could be that life is the result of a higher power intervening in the course of events
But again, we have no evidence how likely it is that said entity would want to sprinkle the universe with life, or just have it here.
The possibility of divine intervention does not help us much in guessing whether there is life elsewhere.
>That is nonsensical. We might get a radio signal, we might see signs of them when a probe flies by, we might see the light show when they fight a nuclear war, they might come to us.
That implies that they are on the same technological level as us or close at least and also implies that they create and advance the same technologies as we did.
Not to mention religion, which can hold back technology and science a lot just based alone on our own history.
Agreed.
>which can hold back technology and science a lot just based alone on our own history
Shut the fuck up.
>abiogenesis
explain further?
Fair enough, but OP's bit about Pluto did not specify any level of advancemtnm, but then went on we could not know about them unless we landed on Pluto.
If they had Pluto Trees, we'd be able to detect the purple foliage dying off as Plutonian Autumn came on, and the leaves turn green and fall off from a fair distance out... Etc... There are ways we could maybe detect life there, or elsewhere before getting to the landing and looking around stage.
Being sure there is NO life may require walking around and looking under rocks...
Probability of intelligent life arising might be small but unbounded growth of life is exponential. Even with few starting planets galaxy would be colonized by life in few million years. Assuming we are average civilization we are neither first or between those firsts. Galaxy should be full of intelligent life but isn't. They are either silent or something is wiping out any competition. Right now there might be intergalactic canon shooting little black holes at us. We can die any second.
You sound like a teenager m8 don't take everything that the textbooks say as "absolute fact"
All the intelligent life either destroyed themselves (like we might do soon) or evolved past physical form and lives in hyperspace.
There might be other earth-like civilizations out there but it's unlikely that they will make contact with us or any other earth-like civilization.
can you prove aliens exist? no
Do aliens exist? maybe
Who gives a fuck if they exist or not? It is likely that we will never contact any extraterrestial life
There's also the possibility that we're just the first lifeforms. The universe is pretty old, but up until relatively recently there would have been a lot of star formation and supernovas that would have made life rather likely to go extinct.
pretty much this.
Does all multicellular life in the universe harbor single cellular mutuals, commensals, or parasites?
(Agressive) (Intelligent) = They would likely wipe us out for our water resources
(Passive) (Intelligent) = They would likely do to us what we do towards tribes that have been protected from civilization, because they are so primitive to our technology.
(Aggressive) (Pathogens) = If we discovered and and tried to bring back samples it could have a hilariously devastating effect on Earth. Pathogens could evolve to make use of animal life, water, and air.
(Passive) (Micro-organisms) This is what I think will likely happen. If we bring a sample back and it starts evolving, what will society respond with as far as ethics? Would we try to destroy it, or keep it alive?
you mean we're the first humans?
First intelligent life, sorry, had a derp.
define intelligent life
That's a tricky question so I'll revise into the much easier and broad category of life with a civilization capable of traveling to space at will
>the elements arecommon
Whoop dee doo. We still have no idea what turns non living matter into primitive life forms.
My understanding is that our emissions into space have fallen off a cliff since fiber-optics and shit got popular. It's entirely possible that the accidental signal era for intelligent life is EXTREMELY short--they move on to other more efficient methods of communication like we have. Also our only example of intelligent life can't be considered to be trying very hard to call up the interstellar neighbors. Even if they are trying to contact other people, it is possible that Earth is somehow an abnormal place for intelligent life to show up so nobody has invested the effort to stop by yet.
This is an awful question because the sample size is one. Imagine trying to find out why America is richer than other countries, but being barred from actually looking at those other countries, or even being given a good definition of "rich."
The absence of evidence is not the evidence of absence senpai. Learn 2 reason famalam.
The universe is gigantic so there's probably other life out there somewhere, but it would be better if there weren't, or it is at least contained in a different galaxy where it won't ever reach us.
Our sun and planet aren't that old though compared to others. ~13 billion year old universe and our planet ~4.5 billion years, surely there are other planets with earth-like conditions much older than ours.
If life evolved on those places similar to how it did on our planet, it could put us at millions or billions of years behind in technology.
Do we even have a rough idea of the sun's age?
not that user but you'd think with all the planets just with-in our own solar system we'd have found some evidence of existence on the planets
what if they are all niggers?
/pol/ please if anything they'd be as alien to us as our animals here on earth.
4,5 billion years?
he said exactly like humans so i extrapolated
missed the exactly part though
You dont know what ur talking about.
Space is fake. Space travel is fake. Planets dont exist. Find Polaris dude
>what is the horizon
If the path of our own species is anything to go by, I doubt any intelligent species maintains a radio-emitting civilization for more than a few thousand years beyond their industrial age. In other words, I think distribution through space is less of an obstacle than distribution through time.
We might be able to find life in the oceans of Europa (one of Jupiter's moons) perhaps deep down where the mantle can heat up the environment. Probably best chance for finding something in our solar system.
We haven't even explored the two best candidates for life in our system yet (Europa and Titan)
Yes, aliens most likely exist, but you don't care about that do you? You don't really care about aliens or what they might be like, you just want to live out your Star Trek manchild fantasies don't you?

You write like you're some fat Mexican high schooler trying to be profound with "facts" you just pulled out of your ass. KYS.

KYS
Like you need to travel to Mars to see it? KYS.
Wow, a post that isn't complete bullshit. Well done my man.
>we have absolutely no idea how life first came into existence
And by "we" you mean "you". KYS.
Holy fucking crap you write like you're fucking 14 years old. Get the FUCK out you underage faggot.
>muhh great silence
Why don't you faggots try thinking for yourselves instead of parroting what some other idiot said? KYSelves.
>They would likely wipe us out for our water resources
Coz' aliens need water rite? Except maybe if they don't. KYS.
That's because you assume all alien life is going to be like earth life. Use your brain for a second nigger. How would YOU detect alien life. Let's say, microbes living deep in the ocean of Europa. How the FUCK would you detect them when you know nothing about them? That's right, you can't. You can just look for weird things, like "oh this atmosphere composition is kinda weird guize mby there are aliens lol!"
I will hijack this thread for a more interesting question who at least can be answered.
Non-westerners of 4chin,
Are you obsessed too by the aliens, finding any sort of bacteria on another planet or it's just western thing ?
What would be sadder, humans being the first sentient race, dead before others show up, or being the last sentient race, arising after everything else is gone?
>last sentient race
that would be even sadder tbhfam
>And by "we" you mean "you". KYS.
>implying you know how life first came about
Oh wow, professor user just solved the mystery of life.
There is, more than likely, life out there. We will never meet them unless they're here right now or no further than one galaxy over. Relativity and evolution make it so that if we were to see evidence of a race of intelligent species, we would not be able to meet them.
As for the complexity of the intelligent organism, shut up everyone. Intelligent life would be able to take on a variety of forms. You could view an army of squids building fusion reactors on a planet that looks conpletely forested. You retards are limited to thinking only bacteria exist outside of our immediate realm. You're uninventive and not practically thinking. Is it chance that earth spawned us? Yes but we have already found 40-some-odd-number of planets that are in the habitable zone of numerous stars, and that's just in our range of vision. Any one of those planets has a nearly identical environment to earth. This means that the presence of water, atmosphere, heat, and even neighboring planets to shield them from meteoric impact are extremely similar. There's definitely species out there that are as advanced if not more advanced than us.
Yeah, what is an "educated guess" anyways?
>Probability of intelligent life arising might be small but unbounded growth of life is exponential.
but the growth of life is not unbounded
Yes, because knowing how nonliving matter turns into life reduces the likelihood of it happening. Someone give this man the Nobel prize!
Are you stupid?
>That's because you assume all alien life is going to be like earth life. Use your brain for a second nigger. How would YOU detect alien life. Let's say, microbes living deep in the ocean of Europa.

Radio waves, planet spectra
The universe could conceivably carry on as normal for another trillion years or more- if this is true, we are existing in the first 1% of time.
We exist so closely to the beginning of time it's nearly detectable to us.
Maybe there's life- maybe it's intelligent. Maybe we, life on earth, are a fluke. Or, perhaps, we are the first.
Any scenario is possible given what we know so far- so for everyone getting excited, why?
You're arguing in real time with another ape who lives on the other side of your planet, wirelessly, about whether or not life exists elsewhere, on a website for characatures of our species being raped by tentacles.
Keep a somewhat open mind.
>(Agressive) (Intelligent) = They would likely wipe us out for our water resources
There's plenty of fucking water out there.
>if they evolved from apes
>a list of terrestrial animals as examples
nigga they might not even be carbon-based or organic, or even fucking cellular. The fact is you need a complex understanding of an alien environment AND a complex understanding of the relationships between any possible species that exist to even consider what an alien might look or function like.
