    We are aligned Alchemist XP!
    Life is abundant in the universe.
    Intelligent life is rare in the universe.
    Life that can travel in space is super duper rare, near impossible.

    I'm not entirely convinced of this one ... Hyperspace / Multidimensional Universe might alter the odds a lot.

    I think it's safe to say that life is more prevalent than intelligent life. That is, we would expect to find planets where simple forms of life never evolved to intelligent forms of life. What we really don't know is how rare intelligent life actually is.

    Capable of space travel? Even harder to know.

    No. It's about life at all. You are the one throwing out the insults for distraction. You seem to be very nervous and angry with anyone who does not agree with your poor science, and I would be as well. You are looking foolish. Again from an astrophysicist

    "But knowing there’s a bird in the bush is not the same as having one in your hand. Similarly, having a planet with the raw ingredients for life and similar conditions to what we had in the early days of Earth doesn’t necessarily guarantee that life will arise on such a planet."

    Why does he say that? Because we do not KNOW how life started here, never mind on a planet with similar qualities and conditions we are not even sure exists.
    Those are the FACTS we have. You can rant on and on about how smart you think you are, how dumb you think I am, and anything else you like. It does not change those facts. Possibilities absolutely. Solid probabilities, laughable.

    If evolution is totally accurate, it would have to be that way.

    Our current thinking on how to get from A to B (some kind of fuel powered vehicle that protects the occupants and baggage for the journey) may not be the key to the puzzle of interstellar travel. I suspect it isn't, but no way to be sure at this point.

    The other observers dont exist. You are imagining them as well.

    Per my later reply, isn't one's mother an observer as well? If she existed only in one's mind, how does one come to be born? And if she does have an actual reality, why cannot other observers?

    But there you have a sample size of more than one, and that's how probability calculation works. You have a sample and extrapolate that to a larger population. The smaller the sample and the larger the population, the larger the margin of error. With a sample size of one, you can't calculate any such probability.

    Around fifty out of three thousand or so -- .017%, roughly.

    Ten billion trillion planets we suspect exist, if statistics bear out: about 17 trillion planets in the Goldilocks zone.

    Of course the sample size is much too small to draw any secure conclusions.

    You were not born. Your mother does not exist. You imagine everything.

    (Sorry if I missed your other posts. Have not had time to catch up with this thread yet)

    These are all good wonderments. :)

    Life so far seems quite opportunistic and robust, conditions permitting, and those 'Goldilox conditions' are ever expanding along various dimensions. Life happened here with a frenzy and there's no reason to doubt any cosmic event happens multiple times and places. Even in our solar system, are we sure there was never ice or water on Mars? Various moons? Underground?

    Thumpy has some numbers above, tentative though.

    My eyes are tired from reading in circles.

    Beam me up Scotty.

    Are these other planets flat too?

    Believe what you want, as you like. That quote does not make your case either though.

    Define 'solid probabilities'.

    Define 'good science'.

    With Tag's logic, we can't be 100% sure until we visit them.
