    I've just been watching a few youtube videos on exoplanets.

    An exoplanet is a planet which orbits a star other than our Sun.

    And scientists have discovered dozens and dozens of different planets orbiting different stars.

    This is pretty damn awesome …

    It is a win win situation for science. either we are the unique planet with life, or it is a common thing. I am fascinated with the unique ratios in our planet system: all tens:

    pressure of atmosphere 10 meters, surface gravity: ~ 10 m sc xsc 10 meter pendulam swings at 10 seconds.

    see the planet 10x further out: Saturn .so:

    Luhe, thanks for the above spectacular species, but sofar, we are still No 1, the first that was discovered to have life, by life.

    Here's an interesting video on the Trappist-1 system.

    Trappist-1 is a red dwarf star about 40 light-years away from Earth.

    There are seven planets which orbit this star, all of their orbits are much closer than Mercury's but because the star is cool and a dwarf, several of these exoplanets inhabit the 'Goldilocks Zone', and so may harbour life.

    Interesting …

    I'm pretty interested in the idea of "rogue planets" without a solar system. Apparently there's a good chance many could have life develop on them.

    Luhe: small stars actually last much longer than medium size ones, like 'our' sun, or large ones. the truth,' the less you eat the longer you live' is true for the heavens too. so:

    If you were to design a paradise planet with the longest lasting life, you would pick a cool. small star as the central furnace. unluckily, our sun is already half finished. so: by by, eternal paradise (barring a miraculous mid flight hydrogen refueling of the sun).

    The solar system has a resonance, wavelength of 300 light seconds, doubling of orbit sizes,

    "rogue planets" without a solar system."

    Q: that would be a cool place, once the heat of contraction, and from radioactive internal sources is exhausted. long live our distant ( 150 0000 000 km) radiation heat source, sol, compliment of 'the father"

    Since the nearest star is 4.24 light years away its all much ado about nothing.

    mbc, yeah, it would make for drawn out zoom meetings. but think how far we have come since the bard. The other "nothing" we like to know about is the one before the Big Beginning of our world.

    basically asking the question: "how did you do all that dad?
