A special place in the universe

This twenty-five minute video clip has just turned my world upside down.

In one of my earliest posts on this blog, way back in 2007, I marvelled at the splendour of the night sky, and concluded that with so very many stars in the universe, the chances that we’re all alone must be vanishingly small.

Watching that video above makes me realize that I was probably wrong about that. Almost all, if not all, of those stars I saw that night are nowhere near anything like our own sun. But it gets worse: it turns out that our sun itself appears to be exceptional, even among its own kind (G-type dwarfs). Possibly only about one half of one percent of stars are like our own.

For intelligent life (as we know it) such as us to exist, we need the following recipe:

  • A star that’s like ours
  • An Earth-like planet orbiting in the goldilocks zone which features:
    • liquid water
    • a molten core (necessary for the magnetosphere, which protects us from cosmic rays)
    • a large moon at just the right distance to stabilize the planet’s tilt (assuming that it has one) and provide regular seasons

Clearly, that’s not an exclusive list.

According to a recent study by Eric Zackrisson, there may be around 700 quintillion planets in the universe. That’s 700,000,000,000,000,000,000. But the study suggests that, of these, ours may be unique.

All of which says to me that homo fatuus brutus, as the de facto stewards of this planet, needs to learn how to pull together to ensure the continuation of a healthy home (instead of doing what we’re doing at the moment, which is destroying it).

  1. On that theme, George Monbiot published a post yesterday, see https://www.monbiot.com/2020/07/25/dysbiosis/ where he described a shocking, terrible future for us all if we don’t change our ways. And, I think, we individuals, are incapable do doing that. It’s not in our nature, however sympathetic we are. It will take leadership from governments and that, at the moment, is in very short supply. I fear for the future.

    I will watch the video a little later.

    I can’t believe we’re on our own in all that space out there, Pendantry, everyone else has probably fled to the farthest stars we can’t see yet. They must’ve seen us coming…

  3. I have now watched the video. It’s an incredible review of the solar system, of the universe, no less. It’s also very humbling.

    Perhaps then, life will have evolved on Earth over billions of years, we have eventually appeared and have looked around, came to understand it all and for a brief moment thought we knew it all. Then it will all die out again with us not knowing what happens in the end and the universe at large will do as it has been doing all along, which is not taking a blind bit of notice and carrying on regardless.
    Makes me not worry about having another beer.

    Awesome video. I knew they were bullshitting us when they said life-planets are a dime a dozen….
