    Is it not viable that beings from another planet don't conform to the 'rules of mother nature' ?

    Personally I do think 'Aliens' are a real thing. There's too much space, too many planets for ours to be the only one that supports life.

    As to whether other planet/s support/s life at the same time as ours, that I'd need to be convinced of.

    I know that its just a single example, I just dont think it "adds up". You reckon it's easier to travel between stars than to melt some ice for example?

    I guess it's cause I think there's nothing intrinsically un-copyable about stuff on earth. If you can travel light years you can certainly knock a few elements about to make what you need etc. We can do that here already, on a very very small scale.

    I think its more likely that alien life will be so different to us that we'd not have any physical stuff they'd want and vice versa.

    Disease is another one I find hard to take seriously. It's pretty hard to catch a disease from a chimp. Have you ever caught a cold from a fish? Or from a lettuce?

    By way of an example.. it takes just over 330,000J of energy to turn a kg of ice into water. Weirdly it doesn't change temperature in absorbing that energy...

    https://en.m.wikipedia.org/wiki/Enth...on?wprov=sfla1

    It takes about 3 million joules to get that same kilo into earth orbit. Then millions more to get it out of solar orbit. Thats before you add in the ship you need to take up and down.

    That's why I said it's all so well gaurded!

    Edit. Dropped a zero, its actually 30 million joules

    ...fails.

    There are so many stars with planets capable of sustaining life that if there are too many for ours to be the only one sustaining life, there are also too many that some of them aren't sustaining life simultaneously.

    Either we're alone or there is a vast number of planets with life. Of course that vast number is minuscule compared with the number of stars and the size of the universe so if there is alien life out there we're very unlikely to meet it.

    Fair. Until we know how many planets there are and how long they'v been around for......

    “Intelligent” life, like us, may not last long.... going on our own record, we could well have bred ourselves to extinction in a few tens of thousands of years. We are certainly on a path for it...
    Every species is on a path for extinction and always was.

    Also we are a carbon based life form, and we have non carbon based life forms on this planet.

    Sounds unlikely. Carry on though; tell us the rest.

    The universe is full of water, even the “stone cold dead” satellites around Jupiter have vast oceans of water, recently discovered to be liquid. It is a very common compound and there does appear to be a big watery “Earth like” planet only 125 light years away.

    Sadly I have formed the opinion that superluminal velocities are impossible. Wormholes, if they exist, cannot transport matter (they collapse or rip matter into fundamental particles). Jump into a black hole and at some point, your feet will be a thousand million times heavier than your head. I think it’s referred to as “ Spaghettification” for obvious reasons.

    So that exoplanet is for all intents and purposes unreachable (in my humble opinion), 125 light years means even if we could accelerate to a reasonable fraction of the speed of light, to get there, decelerate etc it would take conservatively several hundred years.

    The universe it appears always protects itself from paradox, every possible conceivable method for breaking the speed limit has fundamental unresolvable issues. Just because we can imagine it and just because we’ve turned out to be clever little monkeys, doesn’t mean we will ever solve that issue. We are stuck here. Science fiction is just that, a fiction.

    Life may indeed be everywhere, even “intelligent” life, if only because this universe is so unimaginably huge but that also means any other examples could be impossibly distant in both space and time. On a lighter note, it is quite possible life got here embedded in interstellar asteroids; some hardy bacteria or maybe a virus (??) aka panspermia. On top of that, it’s quite possible that happened a few times and we’re not all related. Must admit I often wonder about spiders but especially squid, they could be the closest creatures to “alien” life forms we’ll ever actually meet.
