    Okay. Based on the average weight of a cured goat bladder, how much helium would it need to hold to float? Would one bladder be large enough, or is it a composite balloon were talking here?

    A bit of research indicates that it won't float, a bladder weighs about 50 g and displaces about half of a litre. Helium provides 1.13 g lift per l. So a bladder needs to be on a stick.


    Another problem is that you need gold-beaters skin to contain helium, that is from a cows intestine, not a goat.

    How many sewn together bladders do we need to overcome the critical mass?

    I edited whilst you posted, we need goldbeaters skin to contain helium. Bladders would be too leaky.

    Progress!
    Now, we need to find the numbers on goldbeaters skin, and run them through the ballon makers matrix.

    This is going to happen!

    To see if goat bladders will hold helium so we can reconstruct an ancient Batman party balloon.

    A bit on evolution
    An "exceptional" 530-million-year-old fossil contains what could be the oldest eye ever discovered, according to scientists.
    The remains of the extinct sea creature include an early form of the eye seen in many of today's animals, including crabs, bees and dragonflies.
    Scientists made the find while looking at the well-preserved trilobite fossil.
    These ancestors of spiders and crabs lived in seas during the Palaeozoic era, between 541-251 million years ago.
    They found the ancient creature had a primitive form of compound eye, an optical organ that consists of arrays of tiny visual cells, called ommatidia, similar to those of present-day bees.
    <snip>

    The right eye of the fossil, which was unearthed in Estonia, was partly worn away, giving researchers a clear view inside the organ.
    This revealed details of the eye's structure and function, and how it differs from modern compound eyes.
    The species had poor vision compared with many animals today but it could identify predators and obstacles in its path, researchers believe.
    Its eye consists of approximately 100 ommatidia, which are situated relatively far apart compared to contemporary compounds eyes, the team have found.
    No lens

    Unlike modern compound eyes, the fossil's eye does not have a lens.
    The team believe this is likely to be because the primitive species, called Schmidtiellus reetae, lacked parts of the shell needed for lens formation.
    Prof Brigitte Schoenemann, of Cologne University, who was also involved in the study, said: "This may be the earliest example of an eye that it is possible to find.

    Now if only we can be certain of the date.

He played 'Mr Henry Spindlethroe of the International Atomic Research Association' in a three-minute sketch where he answered Ken's queries about atomic power in his own peculiar way.
    Horne's early demise was a great loss.

    A half life of an isotope is the time it takes for the radioactivity to reduce by half. I learned this age 9.

    The decay rate is not constant, it is inverse exponential, like a cooling water curve.

    And ?

    Okay another serious question. How do you peer review a creationist theory or...ahem...fact? A fellow creationist consults the old testament and says, yep that matches my interpretation.

    As it turns out, they probably aren't.
    After poring over the data, engineers and physicists noted a recurring pattern 33 days long that affected the decay rates of the various radioactive substances. That's a pattern that corresponds to the rotation of the Sun's core. Which got the physicists to thinking that maybe the sun was involved. But the only explanation that makes sense would be solar neutrinos -- which leads to a result that means, as one of the researchers observed, "What we're suggesting is that something that doesn't really interact with anything is changing something that can't be changed."
    OK did you find out what the half life of Potassium40 might be? Go and do that and then comment on what difference a 33 day cycle of variation might make.

    Carbon14 is a non issue as it is already calibrated for variation in C14 production variations.

    Frank, another task for you.
    First have a read of this: https://www.khanacademy.org/science/...nce-of-biology

    Then tell us or give us evidence that Creationists follow these steps:
    1. Make a prediction based on the hypothesis.
    2. Test the prediction.
    3. Iterate: use the results to make new hypotheses or predictions.
