UAP/UFO thread - Non-Human Intelligences

I'm hoping that when they receive those early tv signals they'll remember to tape all the missing Doctor Who episodes as that would fill the gaps in my collection!

On a more serious note it seems more probable than not that the universe is teeming with life. The search for extra solar planets identifies more and more, including life friendly ones. Hydrogen appears to be the most common element in the universe, no reason why oxygen isn't as available, therefore the is likely to be water in some form out there.

Carbon would also be common according to mass spectrometry and if you put those three elements together, under the right conditions, proteins form, that can lead to amino acids.....

So there is likely to be life out there, but is it like us, or primitive, like bacteria or Martin Keown!?! Other star systems may have formed much earlier than our Solar System, perhaps lifeforms evolved formed civilizations, created technology. If so it could be at least thousands of years in advance of ours.

Space is very big, the distance and time to travel to our nearest star systems would be hundreds of years. However for a hi tec civilization with technology far in advance of ours, coming to Earth, might be much easier. Hopefully they'll be benevolent like ET, rather than say Independence Day.

However human history teaches us that whenever one technologically superior civilization encounters a less advanced one, there is usually not a good outcome for the indigenous people........

There are other places in the Solar System to explore, hopefully we can become an interstellar species, and expand our habitats.

“The search for extra solar planets identifies more and more, including life friendly ones…”

In fact there has not been one exo-planet discovered that is within the Goldilocks zone for water and temperature, small enough to have similar gravity to earth that also possesses a magnetosphere, something else essential to prevent a small planet’s surface being irradiated to the point of sterilisation.

I do not disagree that the universe may be teeming with life. There could be billions of intelligent, technological species out there, but as Brian Cox postulates it may well be one per galaxy because of the seemingly almost impossible odds that the necessary conditions occur. Even one per galaxy allows for many billions of species.

I hadn't realised that no habitable zones have been discovered. However there is a lot of discussion on how a planet's geology is, what size from it's star it is etc which potentially may affect the definition of such zones. I think the discovery of extra solar planets is advancing all the time which hopefully will advance our knowledge of when we eventually get there!

There are huge barriers to life forming wherever we look, and if you talk of advanced intelligence, the prospects appear bleak. But the thing that gives me hope is the sheer number of star systems out there, balancing off the unlikelyhood of intelligent life!

There are at least 16 known in the Goldilocks zone out of the 5000 or so known exoplanets.

things like magnetosphere's tough we're only just starting to be able to detect.

Then there's also the issue of we're judging what we think as life sustainable based on our knowledge of life. Earth like gravity for example could be a total misdirect as life could just develop around what ever gravity it has where it evolves.

plus planets outside of the goldilocks zone, if they have plenty of water and a volcanic core could still develop life. Prime example being Enceladus, a moon around Saturn, well outside the goldilock zone but had heat and liquid water under the ice surface. its entirely possible there is life there or could form there.

the criteria we're setting is just best chance.

It's difficult enough to find intelligent life on this planet, let alone others. :)

If life is abundant but intelligent/evolved life is rare in the universe it stands to reason more advanced civilisations would be here observing …the only issue I have with it is how they would travel vast distances of space to get here.

I think the multiverse theory is a plausible alternative to the traditional view (Big Bang) so inter dimensional travel could well be a more likely explanation than travelling these great distances between planets across the universe. I guess as physics advances we will get the answers to some of these questions.

I had a look at the 4chan thread, seems to me the guy is a bullshitter, no real information, and his prose is poor with no ‘detail’ just opinion and claims.

I agree on the 4chan guy - as mentioned I don’t find him credible, I kind of like these thought experiments though. If we did have contact with ETs what might that look like with all its social and geopolitical consequences?

One thing to say though is that the Big Bang is not mutually exclusive with the Many Worlds interpretation - or the multiverse as it’s come to be known. The Big Bang has a vast array of directly observable evidence including the cosmic background radiation and it’s application to Hubble’s Law.

The Many Worlds interpretation is an interpretation of quantum mechanical phenomena, these are just ideas about how we should interpret what we see happening in quantum mechanics which is very weird and not at all intuitive.There’s a lot of different interpretations of quantum mechanics and no good evidence on which interpretation is correct because it almost gets into the realm of metaphysics, it’s very hard to know how to prove.

If you’re interested in some of the interpretations that allow wiggle room for paranormal phenomena then I’d take a look at Quantum Bayesianism (QBism). It’s a bit funky but I quite like it. It sounds a little solipsistic to me but it technically isn’t solipsism.

My point though is that the Big Bang is simply a description of the origin of our own observable universe which is very well evidentially supported. It does not at all mean that there aren’t other universes, though there would be no known way to prove it one way or the other.

They might also be intelligent, and then simply lack physical manipulators like our hands to actually do much with it in material terms. Few animals on earth have hands its kinda niche mostly for certain treeclimbers but an intelligent animal won't necessarily be able either to build tools or machines or an advanced materialistic society with things like fins, hooves or paws.

One part i certaintly question, and one that is argued against by proffesor Nolan too, is that he describes the aliens as "humanoid". It's quite unlikely that extraterrestials would be humanoid given the sheer permutations of variety in enviroments where extraterrestials might potentially originate from.
