'Amazing' New Technology Set To Transform the Search For Alien Life (theguardian.com) 127
Robin McKie writes via The Guardian: Scientists with Breakthrough Listen, the world's largest scientific research program dedicated to finding alien civilizations, say a host of technological developments are about to transform the search for intelligent life in the cosmos. These innovations will be outlined at the group's annual conference, which is to be held in the UK for the first time, in Oxford, this week. Several hundred scientists, from astronomers to zoologists, are expected to attend. "There are amazing technologies that are under development, such as the construction of huge new telescopes in Chile, Africa and Australia, as well as developments in AI," said astronomer Steve Croft, a project scientist with Breakthrough Listen. "They are going to transform how we look for alien civilizations."
Among these new instruments are the Square Kilometer Array, made up of hundreds of radio telescopes now being built in South Africa and Australia, and the Vera Rubin Observatory that is being constructed in Chile. The former will become the world's most powerful radio astronomy facility while the latter, the world's largest camera, will be able to image the entire visible sky every three or four nights, and is expected to help discover millions of new galaxies and stars. Both facilities are set to start observations in the next few years and both will provide data for Breakthrough Listen. Using AI to analyze these vast streams of information for subtle patterns that would reveal evidence of intelligent life will give added power to the search for alien civilizations, added Croft.
"Until now, we have been restricted to looking for signals deliberately sent out by aliens to advertise their existence. The new techniques are going to be so sensitive that, for the first time, we will be able to detect unintentional transmissions as opposed to deliberate ones and will be able to spot alien airport radar, or powerful TV transmitters -- things like that." [...] Croft remains optimistic that we will soon succeed in making contact. "We know that the conditions for life are everywhere, we know that the ingredients for life are everywhere. I think it would be deeply weird if it turned out we were the only inhabited planet in the galaxy or in the universe. But you know, it's possible."

Complex multicellular life took over 3 billion years to evolve on Earth and then Earth went through multiple mass extinction events, and that doesn't bode well the emergence of intelligent life everywhere. Couple that with the unique conditions that Earth has enjoyed that increased the rate of evolution and allowed life to exist in the first place (protective magnetic field, large moon, ozone layer, Jupiter as a cosmic shield) and it doesn't sound too far-fetched to claim that intelligent life is extremely unlikely to evolve in this universe.

Because the universe is awash in ice planets that contain liquid oceans in contact with rock underneath a protective ice crust and with ample sources of internal energy. These are highly stable environments over geologic timescales - much more stable than Earth. Are we to believe that life evolved on these countless bodies, and not one in our celestial neighborhood ultimately led to a spacefaring civilization? That cryovolcanism / fissures / etc never led to surface species on any of them? That no underwater species developed technological civilization that allowed it to explore past its crust, gaze out at the stars, discover that the universe is awash in worlds like theirs, and set out to reach them? That none had portions where land protruded above the ice? That none were on a world that underwent geological change that warmed up their planet?
I just can't buy this argument. IMHO, abiogenesis itself has to be rare. Perhaps abiogenesis isn't as rare, and lots of life that does evolve stays trapped on its planet - but I still think abiogenesis must fundamentally be rare.

The problem with advanced life being abundant - as per the Drake Equation is:
1) The Drake Equation tends to make people suggest that there are a vast number of spacefaring alien civilizations out there "somewhere".
2) A spacefaring civilization has equal odds of having evolved before vs. after humans, so vast numbers before humans.
3) Since celestial timescales are so long, most would have evolved hundreds of millions or even billions of years before humans.
4) Thus, their technology would be mind-bogglingly advanced.
5) Unless all of them had some motive not to expand, they could be expected to have expanded throughout the universe - with an upper limit on velocity of just under the speed of light.
6) Thus they should have formed bubbles of civilization hundreds of millions or even billions of light years across.

Rats learning to set traps off with a stick, crows and other birds learning how to access food from containers. The idea that we are even the sole sentient speices on our own planet is looking increasingly to be false.
We are still probably the most intelligent, although that may well depend on who's measuring and exactly what they are measuring. Octopii have shown amazing levels of intelligence, although it's quite different to ours. Dolphins as well. All this data is suggesting that intelligence and sentience may be an innate property of life, especially of more complex life forms.
So it's looking quite likely that if we find any sort of extraterrestrial life it will have at least a level of intelligence and sentience. Circumstances and local conditions may well dictate the level of it but if life exists at all out there it's likely to be sentient.
There is one caveat here. There is a possibility that sentience and intelligence in other Earth animals arose because of human intelligence, with natural selection bringing it out in other animals as a response to having to share a planet with us. If that's the case then sentience and life may not correlate significantly. But I think that's unlikely. Octopii and doplphins seem to have developed their intelligence entirely seperate to us.

Statistically, it's almost guaranteed there's other sapient life somewhere.
Astrometrically, the distance between them and us is almost guaranteed to be so huge we might as well be alone.
It's really kind of heartbreaking. We're trapped on this little island in these fleeting, fragile bodies.
Correct on all points, especially the last one. We know with near certainty that (given the sheer scale of the universe) there must be sentient life out there. But that scale also means that our civilizations more than likely are separated by such an enormous distance or time that we will never have evidence of each other's existence. Our only hope is that FTL travel (or an analog of such) is actually possible, and the reason we've not observed evidence of anyone else using it is that some version of sta

The Wright Brothers are credited with the first human flight in 1903. Do you honestly think that by 1909 and looking at our still-antiquated flying tech, you could have convinced a single human being that our species would fly to the moon and walk on it, within the next 50 years?

We couldn't even imagine moonwalks in 1909, a mere half-century before we actually did.
Most couldn't imagine it, but some could and did, most of them science fiction writers. Verne wrote about going to the center of the Earth in 1864, a feat far more difficult than going to the moon which is why we haven't achieved it yet and likely will not for centuries if ever.
Had our ignorant greedy species NOT pissed away the last thousand years carving up this dying rock into Yours and Mine endlessly warmongering over it for death and profit, we would most likely BE that species cruising at FTL speeds we cannot even imagine, as we sit here stuck and horribly infected with the Disease of Greed.
Assuming FTL is actually possible, I agree.

I wouldn't say necessarily "alone in the universe", but I do believe that the most likely answer to the Fermi paradox is that we're alone within reasonable relativistic distances, and that faster-than-light travel is physically impossible.
The whole universe doesn't need to be empty to explain the Fermi Paradox. Just our particular neighborhood, and just up to this point in time.
I strongly agree with you though that logic like "We know that the conditions for life are everywhere, we know that the ingredients for life are everywhere" is deeply flawed. The particular environment of at least some portion of the early Earth (which was an extremely different place than today's Earth) proved effective at creating life, but that says nothing about that particular unknown environment being common in the universe. You can't just set out a normal cosmic mix of water and CHONP compounds at room temperature and expect it to just turn into bacteria. The path to self-sustaining hypercycles was almost certainly a fraught one - and the earliest stages (pre-RNA-world) probably didn't even resemble anything we know of as life today.
I'm personally a strong believer in the "metabolism first" school of abiogenesis. That LONG before there's anything even remotely resembling genetics, the first stage is just a natural catalyst reacting energy-rich compounds. And that the reactive radicals released from this leads to the creation (and deposition or trapping-in-vesicles) of random varying compounds, some of which happen to increase the reaction rate, improve fluid flow patterns, and/or encourage the creation of other compounds that increase the reaction rate. That early on we're dealing with highly nonspecific reactions and relatively simple molecules or chaotic chains, and that specificity and efficiency are things that developed into the system at a much later date. There's no RNA, probably no proteins, etc - just a requirement that formation rates of "useful" compounds, weighted by their proportional usefulness, happens faster than their loss and the weighted formation rates of detrimental compounds (for every link in the chain... which early on, needs to be a very short chain!). Built atop this very different scaffold, eventually amines come to play a major role in reactions - from there, leading to proteins (of steadily increasing complexity) and glucosamines, leading to early tRNA to aid in protein formation. RNA and proteins then co-evolve to ever-more efficient synthesis mechanisms, ultimately resulting in the early ribosome.
But the key aspect is the environment, not just the feedstocks themselves. You need some highly specific environment to get this scaffolding to progress in a net-forward manner (faster than loss or formation of detrimental compounds happens), not just "water, energy and some random natural CHONP compounds". Clearly, that environment was - somewhere, in some form - on the early Earth. That doesn't mean it's a common environment in the universe. And even if it were a common environment, it could be a transient environment, one that tends to not exist for very long, and Earth's just happened to be efficient enough and lucky enough to spawn stable independent life before it went away.
I'd also add that IMHO the field has also been held back by a focus on liquid chemistry, when the earliest stages were almost undoubtedly surface chemistry, at a rock-water interface in vesicles / pore space. I mean, I get it - liquid chemistry is much easier to study and esp. to model - but it's (again, IMHO) just not the right paradigm.

So you believe life happened via mechanisms that you can't reproduce or observe anywhere in nature. Would you call that a scientific position?
It appears you are using "transient" to equal, what 2-4 BILLION years? How is it that an environment that is stable enough to cradle life through its early development could then disappear from earth without a trace of the critical life-imparting mechanisms?
