  • these types of exoplanets tend to be much closer to their host star than Earth is to the Sun, sub-Neptunes are too hot to have liquid water on their surface and support life. Instead, they would have atmospheres made of steam, over layers of an exotic phase of water that behaves like neither gas nor liquid. Since the existence of these “steam worlds” were first predicted 20 years ago, interest in their exact makeup and evolution has grown.

    For the first time in history, the James Webb Space Telescope (JWST) confirmed the presence of steam on a handful of sub-Neptunes. Astronomers expect JWST to observe dozens more, which is why such models are critical to connect what we see from the exoplanet’s surface to what is inside of them.

    Icy moons are small, condensed bodies with layered structures: icy crusts over liquid water oceans. Sub-Neptunes are much different. They are vastly more massive—10 to 100 times as much—and, again, they orbit much closer to their stars. So they don’t have icy crusts and liquid oceans like Europa or Enceladus. Instead, they develop thick steam atmospheres and layers of “supercritical water.”

    This exotic, supercritical phase of water has been recreated and studied in laboratories on Earth, exhibiting behavior that is far more complex than simple liquid water or ice—thus, making it difficult to model accurately. Some models even suggest that, under extreme pressure and temperature conditions inside sub-Neptunes, water may even transform into “superionic ice,” a phase in which water molecules reorganize so hydrogen ions move freely through an oxygen lattice.

    Very cool!


  • No, the AI was most certainly trained on the same stack overflow posts as humans would manually search out in the past.

    Thus the effective difference is precisely that between an active attempt to understand and blindly copying since the AI is specifically there to introduce a stochastic opaqueness between truth (i.e. sufficiently curated training data) and interpretation of truth.

    There is a context to stackoverflow posts and comments that can be analyzed from many different perspectives by the human brain (who posted the question with what tone, do the answers/comments tend to agree, how long ago was it posted etc…), by definition the way LLMs work they destroy that in favor of a hallucinating-yet-authoritative disembodied voice.
















  • I mean, yes in so far as you can generalize, of course I am jealous of that!? You think I like being stuck at the bottom of a cruel hole lined with gold and bullet casings?

    What I am saying is open your eyes to your own history and recognize it is part of the same system and process whether or not the locus of power is currently within your empire or not.

    I don’t make this argument as a form of nihilistic relativism or try to rope other countries into the miserable complicity in yet another genocide the US has condemned itself too participating in. The US deserves FAR MORE blame than Germany, the UK, France or any other European country does.

    My point however is, don’t lose focus of the fact that the US is a cancerous reflection of the same tendencies towards empire, fascism, ethnic cleansing and xenophobia European history is full of. US history unfolds directly out of the worst parts of European history, you cannot deny it and if you continue to do so you hamstring your capacity to understand the coming threat to Europe that will eat away at everything your society holds dear in the name of fear of terrorism and the silhouette of an immigrant threatening to join your community and become your neighbor…




  • I have no doubt that the muslims would do the exact same thing, if they had the chance.

    This belief is a prerequisite to turning a blind eye to the Palestinian Genocide or perhaps it is simply the last defense people have for turning a blind eye. Is that you? Is that why you are behaving like a child on such a serious topic?

    Shame on you for responding to a genocide only with laughably speculative handwaving about how in a wildly different situation Muslims who are victims of a genocide would commit genocide.

    This is what you choose to focus on right now?

    Shame on you for lobotimizing your empathy.
