    How arrogant would it be to think we are the only intelligent life in our galaxy with a hundred billion habitable planets? Especially when we have already discovered organic matter on asteroids. It is clearly the vast distance that prevents communications and that could last forever. But the main variable in the Drake equation limiting the number of intelligent species in the universe for which we have no answer (other than ourselves) is: How long does an intelligent civilization live before destroying itself with technology? 😢

    Actually our solar system is extremely unique in the sense that no other solar systems with as many planets as ours are known. There are 402 quantifiable and necessary characteristics of a planetary system and its galaxy that must fall within narrow ranges to allow for the possibility of advanced life’s existence. A slight increase or decrease in the value of any single one of these 402 characteristics would gravely impact that possibility. Remarkably only our solar system meets all of those extremely rare qualities out of all of the solar systems we’ve analyzed to date.

    These planets are not our mother. Looking for Earth 2.0 is like having a chimp gestate and raise human embryos. But actually far more distant the chasm, in terms of biology, micro flora, etc

    20 billion planets. if one in a million actually had life, that would be 20,000 possible civilizations.

    The planet we find to inhabit will already be inhabited 👽

    There are no planets. Just stars. Prove me wrong.

    Unfortunately, none of these objects qualify as planets. Do they orbit the sun? Nope.

    I feel that sometimes we assume that intelligence means to build craft and soar the universe. My gut tells me that this is our niche as humans and shouldn’t expect this outcome when looking.

    You can imagine anything you want... It doesn't make it true.

    With a trillion, trillion stars ... if even one out of a trillion has life... that's a trillion life planets, right?

    The issue is the way our solar system is arranged is turning out to be very unique. Inner rocky planets and gas giants outside so the system orbits will be stable over long periods.

    Whilst It’s possible there may be plenty of microbial life the occurrence of technological civilisations may be far less than one per galaxy, which would explain the fermi paradox.

    Fun fact: There exists a planet 600 light-years away that astronomers believe has a core made out of diamond and if sold, it would give every person in the world, including you and me, 260 trillion dollars, since it has a mass of 14 earths. But since it's so close to it's star, that it's being torn appart by the star's gravitational pull.

    The idea that most stars had planets has been accepted since the 1970s, on angular momentum grounds. Getting photos of them just confirms it.

    Can you extrapolate from this and approximate our chances of meeting an alien race that has six bewbs?

    Jupiter could have been a failed star...I wonder if it could ever light up
