Wait did I just see that confirmed today by the USA military?

Aliens can be anything… except maybe little green men from a far away planet ( as they don’t exist)

The former intelligence official David Grusch, who led analysis of unexplained anomalous
phenomena (UAP) within a US Department of Defense agency, has alleged that the US has
craft of non-human origin.

Jonathan Grey, a current US intelligence official at the National Air and Space
Intelligence Center (Nasic), confirmed the existence of “exotic materials” to the Debrief,
adding: “We are not alone.”

it seems pretty logical to me that with an infinite number of planets, the conditions for life are bound to be replicated elsewhere. Given the age of the universe, its perfectly possible for civilisations to have existed millions of years before we existed and that new life will be born across the universe long after we cease to exist

Yeah definitely

[LeatherTrumpet]

So far what we have explored of the universe (for life) is like

imagine all the earth's oceans are the universe

you walk down to the sea at Blackpool and fill a pint glass of water

look at it and conclude "nope no fish in here"

That's a great analogy

Yes I think given the vastness of it intelligent life (on a par with or in advance of our own) even within our own galaxy is inevitable. Probably dozens if not hundreds of intelligent alien civilisations.

The question is whether or not it's feasible for any of these civilisations to physically reach or even communicate with each other. Tbh the whole thing hinges on faster than light travel (or at least communication) being possible, which it may well not be... Basically we might be surrounded by life, but never see or hear from any of it, and none of them will know about us (or each other) either.

Communication might be more possible because of the theory behind quantum entanglement - in theory it makes communication over huge distances instantaneously possible. That would be a best case scenario if you ask me. If we can see and talk to other intelligent life but it's like... Via Face Time... We can share knowledge but never actually physically reach each other.

However....... This US military chap appears not just to be saying that they exist, but that they are or have been here on earth

There's the question of the Fermi paradox: if the universe is so old another civilisation would have had time to visit, say, all the stars in the galaxy.

Yes that's a good point, I personally feel like a lot of the alien stuff is wishful thinking/fantasist

Yeah there's billions of planets out there, but honestly the odds of us having a planet like this so perfectly suited to so many different forms of life is probably billions to one. We can see thousands of light years away now and so far every other planet is just a heap of rock, even the ones most similar to earth

What about Kepler-452-b?

Looks like a ****hole

Even that it's not really clear if it'd be habitable or not and is nothing like Earth really. And it'd take 26 million years to get there lol

Not if FTL travel isn't possible. Realistically, not even if it is - I feel like you're either underestimating how many stars are in our galaxy (approx 100 billion) or overestimating how old the galaxy is (13.5 billion years). Given how lo g it takes for planets to properly form to the point of supporting life, even WITH faster than light travel, a civilisation would have to visit like 20 stars a year over a span of 5 billion years to visit every star in the galaxy.

Not take away the possibility of FTL travel, and say, theoretically, travel at exactly or 99% the speed of light is possible... It would take about 5 years to travel to just the nearest star, let alone billions of stars. Note that this means it takes at least 5 years to even send a MESSAGE to the nearest star. It's also potentially not even possible to survivably travel even 50% the speed of light.

Basically the Fermi paradox is solved entirely by distance and FTL possibility. If its not physically possible to travel faster than light, then the likelihood of two species encountering each other is very low. Or at least for us, when we know there's nothing on nearby star systems.

Due to the numbers it IS likely that by coincidence, there are aliens out there who happened to have other intelligent alien neighbours in the same solar system or in the nearest star system and would have discovered each other as soon as they started looking. Also what would be fascinating, is that they would have been able to SEE that each other exist hundreds of years before being able to contact each other, and would be able to send messages back and forth decades before being able to physically meet.

You could have a nice long cryo snooze for yourself

I think travel will be accomplished using AI and downloading consciousness to a destination body rather than requiring actual physical travel. So it follows that we "only" need to communicate with aliens

ohhh Interesting, that would be weird if we were able to transfer our consciousness like that someday, the next step in evolution maybe

That's true but we've actually only taken "a good look" at a miniscule number of solar systems. Like LT said, the allegory often used is that saying there's nothing based on what we've looked at, is like taking a glass of water out of the ocean and saying "Nah, there's no fish!"

As observation techniques improve (and are... Ahem... Inevitably taken over by AI which will do it all quicker) I think we may well stumble across habitable worlds or even evidence of intelligent life. But it'll mainly be a curiosity and just a wondrous thing to note... Because we won't ever meet them, or ever even feasibly communicate with them at all. We would be seeing thousands of years into their past also.

If FTL travel is possible then I think the Fermi paradox kicks in - there'd be infinite numbers of species in the universe able to travel unlimited distances, so we should be able to observe that.

IMO the only two possibilities are that FTL isn't a thing no matter how advanced the technology... OR the "bubble" theory... Which is basically that there are other species who are so advanced that they can contain our solar system in a "security bubble" that stops us from accurately seeing out of the bubble until they deem us worthy.

I do quite like that one. It's the only one that matches with UFO's being on earth, also.

The transmission of data is still limited to the speed of light, so 5+ years to the nearest star, potentially thousands of years to the nearest intelligent life. Also consider coordinating the effort with centuries if not millenia between messages back and forth.

I like the theory of quantum entanglement communication being possible (which would in theory be instant - we don't even understand why yet but have observed the effect) BUT even then, initial contact would have to be non-quantum to set up any such quantum entanglement, as I understand it. The "entanglement" has to happen at the same location, but then the particles remain in sync no matter how far you move them from each other (in theory, including lightyears apart). But yeah... The issue is how do you make first contact.

I genuinely think the ability to transfer a human consciousness into a synthetic body isnt that far off, like a few hundred years.

The scary thing is that it wouldn't really be a transfer - it would be a copy - to make it like a transfer you'd then have to kill the one "transferring". The Paul Rudd show "living with yourself" goes I to that quite well I think. Basic premise is that people get this treatment that rejuvenates them and makes their bodies fresh/younger... But it turns out they actually make a clone, transfer the consciousness and destroy the original without the person knowing. (Of course, they mess up and Paul Rudd's original survives, resulting in two Paul Rudd's and much high-jinx).

I've watched it, I'm a fan of Aisling Bea

Or similar to that film Chappie

Iv still to be convinced there is intelligent life in Falkirk tbh

That reminds me of the Futurama episode when Earth is invaded in the year 3000 because a TV program in 1999 got cut off and the aliens watching it were just over a thousand light years away. Fry asks how they can even know about a show from a thousand years ago
