Current Events > No intelligent life in the universe besides us?

So there's no intelligent life in the universe.

Intelligent life probably exists out there, but we will probably never meet them. The distances are too great.

Not just that, but humans are used to working in miles and in years. The universe works in billions of miles and in billions of years.

Maybe there was intelligent life on a planet in another galaxy two billion years ago.

Or maybe there will be two billion years from now.

The distances in time and space are simply too great for it to matter to us.

not sure how those scientists can know that.

The laws of statistics dictate there has to be other intelligent life out there. There's so many stars and planets in the observable universe that we have to use exponents to describe it.

Now when they say we'll never meet other intelligent beings that could very well be true.

so it looks like some scientists at oxford don't agree that the fermi paradox holds any value

that's literally it

so it's one idea without any proof countering another idea without any proof

wow

aliens btfo

Just because we've not found any intelligent life besides us doesn't mean it cannot exist anywhere else, especially when the size of the universe is beyond measure. Literally. It's called the observable universe for a reason.

So my dream of banging a hot alien chick lives on

That's dependent on the odds of intelligent life emerging which we have no way of knowing. If only 1 in a trillion quadrillion planets in the habitable zone ever develop intelligent life we would likely be the only intelligent life then. without knowing how likely intelligent life is you can't say that statistics dictate there must be other intelligent life out there.

There's likely no other life within the observable universe. There are only about 10 billion galaxies, each galaxy has less than 100 billion stars that have a habitable zone, and not all of them planets that could support life. If we're being generous, that leaves only like 10^15 solar systems in the observable universe that have planets that could support life. The chance of life coming into existence on one of those planets is well less than septillianth of a percent, so it's highly unlikely for there to be life elsewhere in the observable universe.

This is being criticized by others. It's just guess work that's basically attempting to answer the Fermi Paradox of "where is the evidence?", which is not a strong argument to begin with given not only the size of the galaxy, but the Universe.

Also arguing that we still can't reliably estimate several of the Drake Equation variables such as the likelihood of life from non-life and the likelihood of that life evolving to an intelligent species capable of "emiting" evidence. But that doesn't mean the answer is no life (well, they're saying no intelligent life, but the same applies)

The current working estimate on the number of galaxies is 2 trillion. And I don't know where you get "The chance of life coming into existence on one of those planets is well less than septillianth of a percent". Sounds made up, but I'm open to a source.

Then, you know, both intelligent species would have to be advanced enough that at least one would even be aware of the other in the timeframes involved.

By the time someone on some other planet realizes what Voyager is, Earth is likely to be a lifeless rock again.

I read some of the paper. It asserts that the Drake Equation is highly flawed because it only takes 7 parameters into consideration. Its math is too shallow and its based on outdated knowledge of astronomy and chemistry. The author is putting forth a more statistically rigorous version of the Drake equation that is several magnitudes larger. He asserts that using his method makes the Fermi Paradox moot.

It's too far away, we may be alone in our space, but there's so many others out there in other galaxies it's not in question there's other intelligent life out there, as intelligent as us or as intelligent as dinosaurs or dogs? That's the unknown.
---

Literally the fact that we even exist is proof that intelligent life could (and very likely does) exist elsewhere in the universe.

It's incredibly presumptuous and arrogant to say that we're some sort of "once in infinity" freak accident. Especially when we ourselves know so little about the universe and its origins.
---

Know one ever thinks that we could just be so stupid compared to aliens that we're seen as completely un-worthy of a visit.

What if there are things out in the universe that we just completely don't understand and never will? Maybe we're perceived as being so far behind, so mentally unable to grasp certain things, that there's just no point.

Or maybe we're viewed as just another planet destined to destroy itself like the hundreds/thousands these aliens have seen before?

Just food for thought. I'm not sure if I believe in aliens or not btw.

We know so little that we consider most diseases are incurable, like genetic diseases, neurodegenerative diseases, herpes, etc. We barely know enough about how our own bodies work.

But obviously we know about intelligent life millions of light years away.

Given an infinite amount of pissibilities, it is also equally as valid that we're alone, I think. But meh, that's no fun.

I think the fact that distances are so unimaginably large between stars that, in a sea of 200-400 billion stars scattered across 200k light years, it would be hard for even the most advanced races to find us, let alone visit us, and that's just this galaxy with a larger sister galaxy holding a trillion stars, over 2 million light years from us. And the hard cap of c does not seem possible to overcome and those that can, are still very sci-fi.

And this does not even factor in that intelligent humans have been around for what's considered a blink of an eye for the Universe.
---

If there is I can guarantee they're all just outside of everyone's field of view so they'll never find out about each other.
---

BS. Some human thinks he/she knows what's out there. *Yawn*
---

I am almost absolutely certain that there are millions upon millions of alien civilizations out there. The Universe is just way too big and vast for it not to be the case.

However, due to said vastness, we will likely never encounter each other unless significant advances in faster-than-light travel are made.

This post is amazing

There's no proof or probability either way, we just don't know. We've no real idea how big the universe is or how small the chances of life are, so these don't get us anywhere closer to an answer either.

That study has as much proof as those that tell you there is no God, neither angels and demons.

Yet religion has masterfully brainwashed millions of people into believing otherwise.

Soooo, none? You can't disprove a negative lol.

It in not impossible that there is other life out there, but it may as well be since we'll never be able to reach them.

I'm saying that in spite of zero proof, people still believe in God and other supernatural beings.

So telling folks there are no aliens is probably going to do very little in altering their belief that there are.

Well, to play devils advocate on the god thing, some could view existence as proof enough. The fact that things are ordered in a way that promotes life on this planet could be convincing to them. If we actually are alone in the universe, maybe that would further reinforce their argument (in their minds).

I can't say one way or the other. I think it would be interesting if there were aliens, and even more interesting if supernatural entites existed.
