    Fun Facts leading to a rethink about life, universe, and dhamma

    Hi all, (feel free to change the title of the thread)

    I was replying in another thread and I thought of something concerning light, which led me to ponder, have you come across some fun fact about anything - science, math, art, our planet, anything, that gave you a pause, an experience of “whoa... I never realized this...”. and possibly led to some insight, even a mini one lasting for a few seconds. If so, please share it with all of us. I think it is fascinating to learn how seemingly random tidbits of information can result in somewhat disproportionately insightful experience.

    I will start:

    Light or photon, a particle of light, takes about 8 minutes to travel from the surface of the sun to the earth. But, it takes on average 50,000 years for that photon to travel from center of the sun to its surface. It means that the sunlight hitting your face today was born 50000 years and 8 minutes ago - the stone age! The light that hits you today came into existence when we had just figured out how to do drawings in caves! The photons that are getting created today won’t leave the sun for another 50000 years!

    Quack quack! - A duck’s quack doesn’t echo anywhere, and no one knows why.

    Nice link! Thanks Aloka, I didn’t know a lot of those things. I wonder if it is a nice feeling to be napping while flying at 25 mph. I can’t even sleep on a plane! I find information about the plant and animal kingdom absolutely fascinating!
    The last one has changed though. Duck quacks do echo, we just don’t hear it! It has been studied scientifically.

    Oh that's a relief, thanks for the information about the quacks - I thought it was rather strange!

    Another interesting photon fact is this, "by studying ancient light radiated shortly after the big bang, a physicist has calculated the minimum lifetime of photons, showing that they must live for at least one billion billion years, if not forever." From Scientific American, https://www.scientificamerican.com/a...fetime-photon/

    I did read that there may be no time experienced by photons, so that they are existing, for them, from the beginning of the universe to the end of the universe in an instant.

    Happiness and money : extracts from 2 articles (cf links below)

    Psychologists from Purdue University and the University of Virginia analyzed World Gallup Poll data from 1.7 million people in 164 countries, and cross-referenced their earnings and life satisfaction. Researchers came up with a bold conclusion: the ideal income for individuals is $95,000 a year for life satisfaction and $60,000 to $75,000 a year for emotional well-being.
    The study found that once that threshold was reached, further increases in income were actually associated with reduced happiness.

    They found that as soon as an ideal income was surpassed, people began clamouring for meaning in more material pursuits, or by comparisons to newly and nearly attainable — but still out of reach — social classes.
    If you do have a bigger house in the neighbourhood, that might encourage everyone else being dissatisfied with their houses, to make their house bigger, and by doing that, they'll lessen their dissatisfaction. And successfully increase yours.

    Happiness, Einstein reminds us, is a moving target and more humble pursuits may actually be favoured if true contentment is your goal.

    Did you know that in Switzerland, it's illegal to own only one guinea pig?

    That's because the furry piglets are social animals and it's considered a form of animal abuse to deprive one of any chance of social contact. As they are not long-lived creatures, when one dies you have to get another pretty soon.

    I think this is a good example of a law demonstrating compassion for sentient beings. Why can't other countries do something similar?

    The first time I learnt about cells in the body regenerating I was absolutely floored! I don’t know why, probably because I was very young. Most cells in your body regenerate except a few like neurons in cerebral cortex and some in the eye etc.

    http://https://www.nytimes.com/2005/08/02/science/your-body-is-younger-than-you-think.html

    http://https://www.livescience.com/33179-does-human-body-replace-cells-seven-years.html

    Long story short, life spans of some cells: (from the second link)
    Red blood cells live for about four months, while white blood cells live on average more than a year. Skin cells live about two or three weeks. Colon cells have it rough: They die off after about four days. Sperm cells have a life span of only about three days, while brain cells typically last an entire lifetime (neurons in the cerebral cortex, for example, are not replaced when they die).
    Gives a scientific perspective on annata and annica.
