Do Aliens Exist?

[pinkybrief]

I just watched district 9, so yes

 

[no fat chicks]

We constantly discover new species on Earth. We constantly find long extinct animals. You don't have proof life....fuck intelligent...but life at all exists outside of Earth. Why can't a unicorn or a ghost be on Mars but aliens can?
Better yet, why do you think aliens would even exist.

Funny thing is that when "scientists" claim that some planet could support life it is always a planet they say is like Earth? But wouldn't that mean that we would expect to find animals and plants close to or the same as what is on Earth vs the Greys or whatever? The thought is they would be carbon based.

We are all contained by the speed of light. If there were anything in say the Andromeda galaxy ---- our closest neighboring galaxy, that we would never meet. We would never see each other. The closest we would ever get is communicating with them via radio waves and shit and we have been trying that for decades now and not a single fucking thing.

Fact is that all the crazy shit I am saying to find on Earth is much more likely than finding aliens because aliens are zero and unicorns are more than zero because we have horses at least...we have living things at least.

LOL, I might have to get serious here if it gets interesting.



They play instruments and drive cars in the Andromeda Galaxy

This post is madness poured out for all to see.

Can you tell me the number of habital planets that are estimated to be in our own Galaxy? Get that number and tell me with a straight face you don't think we're the only other life in the universe.

1) The universe is not infinite. Sorry. There is no evidence supporting that. The static model is long gone. Get out of the 19th century.

2) It's a reasonable assumption to make using statistical analysis.

Say who? Besides you? The statistic is that only on Earth is there life and there is on one Earth. Sorry reality works like this.

Hey, there are horses and there are animals that fly on Earth...statistically speaking we could have a Pegasus flying around or a unicorn.

Lol dumbest post I've seen in sometime. I laughed for a solid minute. Thanks.

 

[Frode Falch]

I believe in aliens on other planets. I dont believe there have been aliens visiting earth.

I think he has a point. Habitable (meaning earth-like I guess) doesn't automatically mean life. We cannot calculate the odds of life spontaneously forming as we only have one example. It could be that it's nearly a sure thing given some fairly common conditions and that would mean life all over the universe. But if the odds are incredibly low and even then require very specific conditions then there could be none at all. Without knowing the odds of abiogenesis, we can't really speculate on the chances of life elsewhere. All the calculations seem to be based on it being pretty much a sure thing - but should we be making that assumption?

One thing that is funny is that it took like about 3 billion years to develop from one cell to multicellular lifeforms. So any alien looking at earth for most of its existence would not see animals roaming around or forests etc, yet alone signs of intelligent life.

Humans are the product of aliens fucking primates

We don't have to calculate the odds of life spontaneously forming. We just have to know that the probability is not zero, which we do because we exist. So then, what is the probability? As long as the probability is not below 10 to the negative 10 times one hundred thousand million times two hundred billion, which is basically 0.000000000000000000000000000 (a lot more zeroes) 001, then we can say with reasonable certainty that there is alien life. And that's a conservative estimate as they expect, using math as injust did there, that there are 200 billion galaxies which doubles the 100 billion I used. In other words, you have a better chance of playing and winning the powerball jackpot hundreds of times in your life, if not thousands, than there being no life other than ours in the universe. I'll take those odds.

As big as the numbers are, you still need to know the odds of life forming spontaneously, and just how specific the conditions need to me.

And of course life might only survive very briefly under other circumstances. It's just about a self replicating molecule - those have to survive and develop over time.

One thing to bear in mind is that all life on earth appears to be from one cell. If life under benign conditions forms so readily, how come it doesn't appear to have formed over and over again on the one planet we know for sure supports it? Why isn't it happening right now? Maybe it really is incredibly unlikely.

My guess is that life does exist elsewhere but I'm not so sure it's a dead certainty.

No. No, you don't. You just have to know what they are not. They are not zero. Do you really think that you have a shot at winning the powerball jackpot multiple times in your life? Of course not. And if you don't, you have to concede that life is out there. Of course nobody can say with certainty. But it is a very reasonable assumption.

 

[Aegon Spengler]

Yeah there is probably life, probably a bunch of dinosaurs.

 

[Codger]

No. No, you don't. You just have to know what they are not. They are not zero. Do you really think that you have a shot at winning the powerball jackpot multiple times in your life? Of course not. And if you don't, you have to concede that life is out there. Of course nobody can say with certainty. But it is a very reasonable assumption.

I'm not saying you need the exact number. I'm saying you need to know that it's high enough for all the opportunities on other planets to make it likely to happen again. We don't know that. It might be that it's so low that it's even a miracle it happened just once and there is practically no chance of it happening anywhere else. All you're doing is repeating that the number of planets is very large and therefore the odds of it happening only need to be very low. I know what. What I don't know is the odds of it happening. It's possible it's a very low number, even in astronomical terms.

What are your thoughts on my questions? Why hasn't it happened again and again on earth over the last few billion years if all it takes is benign Goldilocks conditions?

No, I'm trying to illustrate just how unlikely it is that there is not life anywhere else. Again, if you don't think you have a shot at winning the powerball jackpot multiple times, you have to concede that life is out there. It really is that simple.

Also, why hasn't new life formed in the past billion years? Are you sure it hasn't? They find new species of insects in the rain forests all the time. How do you know there aren't new species of single cell organisms being found? And if there aren't, it's likely because the single cell organisms that exists are consuming the materials needed to create new ones. A vacuum may have to exist, in which there is no life, for life to occur.

 

[M3t4tr0n]

If aliens do exist on other planets are those planets flat too?

 

[Codger]

If I don't think I have a shot of winning the powerball multiple times I have to conceded life is out there? Why? I could win it 3 times if I bought 3 tickets over 3 weeks. How does that chance the fact that the odds of life forming have to be high enough such that it's likely to happen at least once on the many other planets out there. We don't know those odds. That is a fact and no powerball analogy changes that. Yes the odds appear to be stacked in favour of it happening because of the sheer number of planets but then the odds of it happening at all could be smaller.
It's not even worth arguing about as it's a simple fact. It could be that unlikely. If it is, then we're still here talking about it as the self selected example. We can't tell.

Given the size of the universe, all sorts of incredibly unlikely events will occur. It's possible that life forming is one of those.

Well one of the main tenets of the theory of evolution is that life all comes from a single ancestor cell and that's never once been shown to be wrong, though genetic and biochemical analysis. So as far as I know, there is no evidence it has.

Life appears to have formed once and then spread. Before it spread to the entire planet, there were resources abound. Yet it life didn't form to use them. Also there are plenty of resources for newly evolved or foreign lifeforms to move in and take over. Happens all the time. Why not a new lifeform? Lack of resources is not a convincing argument.

It appears more like that the conditions and events that created life are not what we have have today but something rather specific in a point in time.

EDIT: one other thing that occurs to me - life stayed in a very simple form for over 3 billion years. Countless cell divisions occurred in that time. I don't know the numbers but we're well into insane, astronomical numbers. And yet not one complex cell occured. And then, as current science seems to think a particular bacterium was incorporated to form the mitrochondria that all our complex cells have today allowing sufficient energy production - by the numbers an unbelievably unlikely event that led to complex cells, then mulitcellular lifeforms and eventually to us here today. This event is something they're fairly sure only happened once and is the only thing that allowed complex life to form.

There you have an example of something very, very unlikely happening just once despite the vast numbers of cells on the planet for over 3 billions of years (bear in mind the universe is only 13.5 billion years old and some of that time it was way too energetic for life) that is crucial for life to exist as we know it today. It could have very easily never have happened.

You don't know the odds. No one does. You need an event to happen at least TWICE to begin ascertaining odds. We have one example of a planet harboring life. Right now the percentage of life outside of earth is ZERO.
Fucking statistics...learn them live them love them.

 

[FadeLess]

Absolutely. Zero doubt in my mind.



Just because we (Most likely a very young civilization) haven't figured it out, doesn't mean someone or something else hasn't. I am confident that technology exists, and has for a long time. Just not on Earth. There have been countless sightings of alien spacecraft on video and in photos. In our skies, around the ISS, around Mars, and around the moon. People not accepting or believing that doesn't mean it isn't happening.

The amount of Ufologists and UFO researchers dying in strange ways for no reason is enough for me to believe. Like committing "suicide" with two gunshot wounds to the back of the skull strange.

We have figured it out, in theory.
We need to bend the space/time fabric, by generating (or accessing and amplifying) an intense gravitational field. The more intense the gravitational field is, the greater the distortion of space/time, and the shorter the distance between 2 points.
But we are yet to be able to access gravity A wave (works at an atomic scale) using any matter found or synthesized here on Earth, but it doesnt mean that that necessary matter doesnt exist elsewhere in the Universe.

 

[edirp]

I don't think so but Big Foots do exist.

When I was about 6, my father took us camping in the Sierra Nevada. We saw a Big Foot tossing around a boulder the size of a tire like it was nothing. It turned its head towards us and we ran off. It was very scary. Since then, I never had another encounter with Big Foot again.

I bet if you caught a fish in the ocean, you would think it was the only fish in there and shit. You can continue being fucking stupid, but that doesn't mean the rest of us want to be stupid with you. Math and statistics are used to predict and prove a number of things that are not physically observable.

You're saying there is absolutely no life outside of Earth. Though you have no way of verifying that and we have directly observed nothing outside our solar system, and barely anything inside it. I'm telling you what the probability is that there is life outside of Earth. So put your money where your mouth is and play the powerball lottery if you feel that strongly. Because you have a much better chance of winning that than being right about this. And by a significant margin.

You don't need to know if an event happen twice to ascertain odds. Where did you get that tidbit from?

Close. But you underestimate the vastness of space. Space is so incredibly large that unlikely events probably occur multiple times. So even if the occurrence of life is at the absolute tail end of the bell curve, it likely happens more than a few times.

And I'm not a biologist. But it would seem to me that for life to spontaneously genesis from amino acids and other building blocks, those building blocks would have to be present in some abundance, meaning there was currently no life there to consume them. I don't know about that life all generating from one single parent cell though. That sounds wrong. I would have to see a source for that.

Also, you could win the powerball jackpot three times. But you won't. There could be no life other than ours. But there probably is. This is how stats work. I can say with reasonable certainty that you won't win the powerball even once. Just like I can say with reasonable certainty, that there is life outside of Earth.
