I was going off memory having just looked them back up, water bears are resistant to radiation, whilst it's a fungus organism that eats it. Both are extremophiles.

So are you implying aliens destroyed the Baltimore bridge? Interested to see Pottsey’s stance on that.

Let's hope it was a simple case of posting in the wrong thread and @mrk doesn't actually believe little green men were involved

They can survive in the vacuum of space, if that isn't extreme then what is? The only reason they aren't officially classified as one is because they're not naturally adapted to live out in such conditions whereas that fungus in radiation is.

Which is one of the things I said in the post you replied to.
And nothing that says it could. We know next to nothing. We don't even know what life is, let alone what conditions are required for it. Or how it begins. Or if it begins. Maybe life is inherent to the universe and has existed since the beginning of time. Maybe it's a bizarrely unlikely occurrence that has only ever happened once.
Silicon based life seems highly unlikely unless you're talking about life on silicon-based computers. For biological life, silicon is an extremely poor second to carbon. Maybe not viable at all, in any conditions. But since we don't know what life is, we can't rule anything out. Maybe it's possible for a rock to be alive. Or a planet. Or a galaxy. Or anything. Maybe the universe is a living thing and we're its tiny symbionts. Or parasites. Maybe we're part of it, like a liver or a toenail. Or not.
Speculation can be interesting, but on this subject it's way out there in the breeze with its foundation varying from gossamer thin to non-existent. Not only do we not know what exists, we don't even know what might possibly exist. We may as well be speculating about an animal when all we have is a drawing of part of a single hair of that animal.
To an extent. But I'm well aware that's all it is - my imagination. I can also imagine that life exists nowhere else in the universe. Or that all life elsewhere is simple single celled prokaryotic organisms because eukaryotic cells are such a freakishly unlikely development that it only happened once. Or that there are a million different species of people from different worlds with advanced technology living in a stable federation of some sort in this galaxy alone, with interstellar travel. I can imagine all sorts of things. But it's just my imagination.
Probably but maybe not. We haven't proved that the special theory of relativity still applies at that speed. When a theory returns a result of infinity it's often because the theory no longer applies under the conditions that return that result. Also, we know that the special theory of relativity isn't a complete explanation of how everything works. It doesn't include gravity and we know it doesn't work on all scales. The incompatibility between relativity and quantum theory proves that neither is the complete answer.
Yes, but they all require water. A few can endure without water for a while in some form of suspended animation. And your memory was slightly faulty (tardigrades don't eat radiation - that's a different lifeform), but I see from later posts you know that.
I think the champion of durability is still Conan the Bacterium. I forget its formal name, but it was playfully named that by researchers. I'll look it up...Deinococcus radiodurans
I'm a chemist, and yes there is - its called science.
Silicone life is impossible, and it a gross misunderstanding of chemistry thats over 60 years old.
The temperature of liquid methane and various other factors make it also next to impossible to have complex molecules form, enough to give complex systems i.e. life.
people say a lot of crap that they are not remotely qualified to have an opinion in - its widely accepted that life is only realistically possible within a narrow temperature range, and water happens to be the best, most common, solvent in those conditions. Its very highly doubtful that life would not involve liquid water significantly.

Life as we know it sure, but new advances and findings bring about new evidence quite often. For astronomy people once thought the Earth was the centre of the solar system for example. People were quite literally killed for heresy for saying anything outside of that fact. You're doing what mainstream science does quite often, getting stuck in tunnel vision... and brush off any idea because it goes against what they know even if it's later proven to be plausible.
Take archaeology as one prime example, until Gobekli Tepe was discovered, science said that humans did not build monolithic structures that far back since there was no evidence of it. The mainstream was sure of that fact... Until they weren't sure and it was only in the 2000s they finally recognised the discovery as "one of the first manifestations of human-made monumental architecture". That's just one example, there are many of them covering all walks of science and astronomy based on more modern discoveries thanks to tech advances.
There was an article on ies from a few years ago that summed it up well, didn't outright say that it's impossible, but very carefully worded the writing in such a way as to not need an edit years/decades to come if a discovery is made, because in science new evidence for things are regularly found to either prove or disprove a theory, so until disproven, the chance of silicon life isn't 0%, it's just 0% for life as we know it.

having a little bit of silicon in a carbon based molecule doesn't make it silicon based - its still carbon based.
Silicon as an element simply doesn't have the chemical capability to form molecules like carbon does - its not about something thats undiscovered or unknown, its a basic chemical fact about the element. Its not going to happen anywhere in this universe.
Both those article are basically a no, with a pointless tease to get people to read them - but the answer is still a no. We know how chemistry works, well enough to be sure.

It's a bit of a leap to drop in a comment about silicon based life though isn't it? Pretty much the theme of this entire thread:
Person A "Aliens / silicone based life could exist"
Person B "We have no proof / it's impossible"
Person A "But it's probable in the universe, because it's huge"
Person B "Sure maybe, although we have no proof yet"
I'd say your first article @mrk linked does say it's impossible - it's a little misleading to say otherwise. There are more interesting quotes from the NBC article about carbon-silicon bonds but you chose the bit about Star Trek

With some the theme seems to be "It is space so anything however ridiculous is possible"

It's all good discussion whatever way someone floats really yeah.
Not sure why anyone would be interested in my view on this. Crazy would be my answer to anyone trying to blame it on Aliens. Surly that is miss post into the wrong thread not someone blaming aliens. At this point everything I have seen points to it being a genuine accident. While a little rare nothing that unusual.

I just watched an interview with Adam Frank, an astrophysics professor and I think I completely agree with him on all this. Under standing what he's saying in particular in relation to intergalactic vs inter-planetary species vs how long a civilisation actually survives and the actual limitations imposed by the reality of physics.
The gist? We are not alone, but other species are not inter galactic, most likely. But if they are, then there is no reliable data for science to "scaffold" up with. At least not yet.

Just watched this rather sobering documentary on Prime if anyone has access - it debunks a lot of the 'evidence' discussed in this thread:
or search:
There is a section where they get an expert to check the military airplane videos and he completely destroys them.
Watch The UFO Movie THEY Don't Want You to See | Prime Video
This film gives the real science behind the current UFO phenomenon and answers the questions so many are wondering. What is in our skies? What do we know, and how do we know it? And most importantly: Are we being visited?
