    822-Dark Matter and Alien Beings
    2024/11/08
    In a recent paper published in the International Journal of Astrobiology, a philosopher Dr. Vojin Rakić (voyin rack itch) reviews some 50 or so proposed solutions to Fermi’s paradox, including, that human life is so exceptional that it happened only once in the universe, that perhaps other civilizations destroy themselves like we are trying to do, civilizations broadcast radio and TV signals only for a relatively brief period of time, alien intelligent life maybe incomprehensible to our species, and that maybe the energy requirements and distances in the Milky way are too great allow us to discover others of our kind and many more ideas. After sorting through all of these concepts, Dr. Rakić (rack itch) suggests that alien life might be unobservable to the senses evolution has given humans and/or perhaps alien beings live in part of the wider universe we don't know of or cannot yet detect and observe.

    The National Oceanic and Atmospheric Administration has published an extensive data based review, analysis, and summary of the Earth's Climate. 2016 was hotter than 2015 which was hotter than 2014. 2016 is the warmest year the Earth has been in the more than 180 years of record keeping. Overall in 2016 the whole Earth was 1.8 F above the 1951-1980 average. The Arctic in 2016 was 7.2F higher than it was the pre-industrial age.

    821-Dinosaur Killing Asteroid
    2024/11/01
    Scientific results are consistent with the hypothesis that the dinosaur killing, K-T layer forming Chicxulub impactor came from well beyond Jupiter while the other 5 impactors in the past 541 million years as well as most meteorites found on Earth came from asteroids formed between Mars and Jupiter. All of this prompts us to marvel that we are here at all and puzzle over how to prepare for what the future might hold. In particular asteroid hunters should take seriously the possibility of an impactor from deep space with our number on it.
