    So, like all the stars you see at night?

    We see nothing. Only emitted and reflected light. All is illusion.

    Is it close enough to look super cool though?

    Do supernova have coinciding Neutrino emission changes, and if so, would we get a warning before the light reached us?

    The crab nebula was formed by a supernova estimated at -6 visual magnitude and recorded across the world. But that was 10x further away than Betelgeuse so we can expect this would be about -11 magnitude or about a quarter as bright as a full moon is
    If you were standing on one of the furthest dwarf planets in the solar system we know of (Sedna) it would rival the sun in brightness

    Yes! It might get bright enough for a month or two to be visible during the day.

    Even though it was written in 1988, the science has healed up fantastically. A lot of the more theoretical topics he covers have been experimentally confirmed over the last decades.

    The NARS team has released a new article about The System. My name isn't on this one but it's a culmination of our recent work on NAL9, the part of the system designed to deal with weird concepts like "SELF" and meta cognition events and such.

    It's also a good overall introduction to NARS in general. If you have any interest in machine learning/artificial intelligence I suggest you give it a read.

    This doesn't seem to be complete; Is there a full look at the NARS operations somewhere?
    I suspect that internal operations such as input rejection are likely in the model but not described here for brevity.

    Also is the software publicly available, and what does it run on?

    Weird question, but has anyone ever considered crowd funding research? Like a Kickstarter to produce a paper + data sets available to the public or something?

    Yeah, it's Experiment.com. Scientists and students submit research proposals that need funding and people can make pledges to support it. The site is run and moderated by scientists, so they filter out any obvious BS and only post proposals that have some planning and breakdown of funding behind them.

    It's like Kickstarter in that if it's not fully funded the pledges are not collected, but unlike Kickstarter in that you're mostly doing it for good feelings of supporting science and not because you're eventually going to get a minimalist wallet or something. Most of the people though will keep you updated on their projects and send links to papers if/when they're published (usually give a thanks to people in the papers too). It's pretty neat stuff, like one study to see how many beavers are eaten by wolves, which had a lot of relevant data but also updates with tidbits like how when the blueberries get ripe and are plentiful, wolves mostly switch to eating berries for a couple weeks (with pictures of beautiful vistas, blueberry bushes, and berry-filled wolf scat). I like to sign on when I have spare cash and make pledges to things that interest me.

    So, how does this system handle creativity?
    Can it generate its own questions to handle new cases?

    I would expect the main question that needs generating is 'new thing --> old thing?' which would then do questions on whether new thing has the intension/properties of old thing, even when there is a minimal or no shared evidence base between the two elements, and thus no direct inference chain connecting the two.
    .. I guess such a question would be generated from 'new thing --> ?'
    ... Which itself might just be triggered directly from sense input (when a new NARS token is observed, or perhaps it is always asked when a token is observed, and object permanence occurs later as a concept).

    It can generate its own questions and there have been some examples of novel behavior in certain experiments.

    Speaking of experiment.com, Science (the journal) just published a study about the effectiveness of scientific crowdfunding, basically just analyzing all the projects from the site. Nothing big, just thought it was timely.

    ‪Remember the BBC documentary series Blue Planet, and Blue Planet II, by David Attenborough that I gushed about in this very thread?

    ‪Well marine biologists enjoyed it so much they have named a newly discovered species of plankton after it.

    If you have any interest whatsoever in Marine Biology, you really, really should watch Blue Planet II. Or even the older series Blue Planet. They’re both well worth a look, and Blue Planet is on Netflix.

    He used to run a nonprofit which he ran into massive losses which, it turned out, was because he was diverting resources from the nonprofit to another company he owned which he was running for profit. And he’s a climate change denier.

    There's also substantial pushback on the nomination of someone as partisan as Bridenstine to what is nominally a nonpartisan position. His record on climate change isn't stellar and NASA manages orbiting climate observatories.

    Butchered rhino remains (along with other animals) and stone tools have been found in the Philippines - dated to a bit over 700,000 years ago. No hominid remains have been found, but this dates to before the existence of Homo sapiens. What's especially interesting is that there is no known land bridge between the Philippines and the rest of southeast Asia, even when sea levels were at their lowest during the heights of the Ice Age. These hominids had to have crossed ocean water somehow to make it there.

    The evidence is clear, 700.000 years ago rhino's used tools, and performed ritual sacrifices.

    I've always maintained that the earliest rumblings of civilization took more than a few tries to take hold and was never exclusive to the domain of homo sapiens sapiens. Even if they were limited by brain size (in relation to body size) all species of homo should be fully capable of tool making and complex social groups. If a corvid (with a much lower brain to body ratio than early homo) can make simple tooks from sticks, a sapient ape should be able to manage even better what with their hands and opposable thumbs.
