UAP/UFO thread - Non-Human Intelligences

[denislawsbackheel]

assume they've been mentioned already but I read Erich von Däniken's books years ago and enjoyed them.

I enjoyed Star Trek.

In my view, the chances of intelligent life in the universe equal to or more advanced than our own is 100%. In an infinite universe there must be infinite possibilities so it must be the case.

So, the chances of a civilisation of such advanced technical capabilities that they can reach earth must also be 100%? Maybe not, as breaking the speed of light barrier also requires infinite energy, according to Einstein at least.

My hunch is that Einstein was right, and it’s impossible no matter how much you evolve and develop your tech. Physics is physics.

They’re all out there, we just can’t hear each other yet.

So I don’t believe aliens are on earth, no. But I am entirely convinced that our neighbours are ‘out there’.

Did you not read Sky blue Flux’s post or don’t you understand it?

Oi, no need to be a rude wanker.

I haven’t trawled the thread no, just saw it pop up and expressed my opinion. I haven’t studied physics since GCSEs so I am no expert, not claimed to be!

If he’s posted something with more expertise I’ll gladly read it but I don’t by default trawl through thousands of posts on every thread I post on, I have other things in my life to do.

If the universe was truly infinite, then your logic might be correct. The observable universe is finite, though. And what is outside the light cone of our observable universe is unable to impact us due to relativity.

Edit: just seen your exchange above - how dare you not read my post mate ;)

I feel like I've made this point on here before but as it seems to be back in vogue... I see a lot of people make the argument "the universe is so vast and beyond our comprehension, the odds are that there must be some other life out there."

From a purely statistical standpoint, this is actually not a very robust argument at all. It's a kind of mental trap or fallacy that intuitively feels correct, but doesn't hold water. Humans are really not very good at understanding extreme odds intuitively.

We have a sample size of one. So we cannot infer anything about the odds of life occurring without knowing intimately the mechanism through which life comes to be (which we know a bit about, but safe to say we are far from understanding fully). It could be very common, it could be rare but not so rare we won't find, but it also could be so incredibly rare that the odds of life occurring are the same order of magnitude small as the universe is large.

Put it this way, say you shuffle a deck of cards and deal it. The odds that all the cards come out in perfect order - all hearts Ace to King, then all diamonds Ace to King etc. is about 10^68. That's way more than the number of planets in the observable universe. There's a very real possibility that the odds of intelligent life occurring are at that level of magnitude. So if you shuffled a deck of truly random cards on every planet in the entire universe, and dealt it every second for the entire time the universe has existed, you'd be unlikely to see a perfect deck dealt even once.

There's this thing called the Anthropic Principle. We look around and say, "Well, we're here, so how unlikely can it possibly be? If we're here, then it must be common." But what this perspective misses is that if the conditions were different and we weren't here then we wouldn't be able to even ask that question in the first place. To enquire about the frequency of life in the universe, you necessarily need to exist to begin with. In both a universe where there is intelligent life on every planet, and a universe where we are the only ones, we would be thinking exactly the same thing - the actual probability in play has no impact on that way of thinking.

So this is the reason that, while I know it's not common to think this way at the moment, if people ask me "is there life out there?" I have to concede, the chances are there actually might not be. And I have no good evidence to suggest otherwise.

Unless of course you believe Lue Elizondo...

That's like finding an ant in your garden and arguing the odds are he's the likely the only one in the whole garden. Because it seems a philosophical enough take. But the reality is, not a chance in hell there isn't more of them somewhere around.

Well - two problems with that. Firstly, we know there are literally quadrillions of ants on earth. And we know how ants reproduce, and travel, and we know they live in colonies. Whereas we have literally one example of a planet with life on it - a single one. So it is a false equivalency, unless this ant was the only one that had ever been found in human history.

Secondly, I am not the one claiming something is unlikely or likely - I am the one saying we do not know because we only have one example, and we don't know enough about how that one example came into existence. It is other people who are saying it is likely. I am simply saying that suggesting it is likely is an assumption.

It's a lot more like finding a goliath birdeater tarantula in your garden in Manchester and saying - "well we can only see one, and until we know how it got there it would be unwise to guess at whether it's the only one or not".

The human mind does like to fantasize, though.

And intuitively narrow down/dismiss too.

Your post is claiming it as unlikely. As is your deck of cards analogy, which is a bit nonsense as if you infinitely shuffeled infinite decks, then the odds of thatboerfect deal become possible. And although there are theories that the universe is finite, it is effectively infonite to a scale that can be comprehended.

It is the basic human restriction of our own knowledge. I.e what we don't know, let's dismiss. Rather than, what we don't know may have possibilities we aren't aware of.

Some of the most dedicated scientists in this field have over decades concluded that the possibilites exist and have soent their careers on it. There are others that take an opposite view. Both are theoretic bith have believable logic and science behind them. There have been many distant planets identified as opportune to life on them, based only on the conditions we know, similar to ours. So the possibilities do exist, just in the small sample we Can observe. Exponentially then what we can't makes it even more likely.

Back to that ant, it is really us that are the ants in the grand scheme of things. Does an ant in a group of ants in Manchester know the extent of the city, that it is and how it is connected with other cities across the globe that all have other groups of ants in them that will most likely never see each other etc etc. Probably not. That doesn't mean they don't exist, just because that is beyond his level of comprehension.

Rightly so. Dismiss until we have real evidence. Same with any amazing claim.

The funny thing is when you see pictures of Earth you never see satellites or the space station or the rubbish that Russia and the USA have left up there over the years,
