    So I assumed the rotas were about 3 meters from the cocpit and asked Gemini.

    To calculate the g-force experienced during this acceleration, we need to go through a few steps:

    1. Convert Mach 19 to meters per second (m/s):
    • The speed of sound in air varies with temperature. At a standard temperature of 20°C (68°F), the speed of sound is approximately 343 m/s.
    • Mach 19 is 19 times the speed of sound.
    • Therefore, Mach 19 ≈ 19 * 343 m/s = 6517 m/s.
    1. Calculate the acceleration in m/s²: We can use the following kinematic equation:
    • v_f² = v_i² + 2 * a * Δx
      • Where:
        • v_f is the final velocity (6517 m/s)
        • v_i is the initial velocity (0 m/s, assuming starting from rest)
        • a is the acceleration (what we want to find)
        • Δx is the distance (3 meters)
    • Plugging in the values:
      • (6517 m/s)² = (0 m/s)² + 2 * a * (3 m)
      • 42,471,289 m²/s² = 6 * a m
      • a = 42,471,289 m²/s² / 6 m
      • a ≈ 7,078,548.17 m/s²
    1. Convert the acceleration to g’s:
    • One g is the acceleration due to gravity at the Earth’s surface, which is approximately 9.81 m/s².
    • To find the acceleration in g’s, divide the calculated acceleration by the value of one g:
      • g-force = a / 9.81 m/s²
      • g-force = 7,078,548.17 m/s² / 9.81 m/s²
      • g-force ≈ 721,564.5 g Therefore, you would experience an acceleration of approximately 721,564.5 g while accelerating to Mach 19 over a distance of 3 meters. Important Note: This is an extremely high level of acceleration, far beyond what any known biological organism or material could withstand. Such forces would be instantly fatal and would likely cause catastrophic structural failure.

    I’m sure someone who’s better at maths than me can tell me where the llm has gone wrong. But it sounds impressive.






  • Ok so your prediction won’t be perfect, it’ll be a fraction of a percent off one way or another. It will be a figure that’s statistically irrelevant. Flip a coin a ten thousand you’re not likely to get exactly 5000 heads and 5000 tails. You’ll get a bit over five thousand of one and a bit under five thousand of the other. What your really fucking unlikely to get 10000 heads unless your name is Rosencrantz

    Was Earth hotter than now before? Sure, why else do we find mummified animals and perfectly preserved roads and settlements under the melting ice!

    Except the key point that denialists seem to forget is those changes happened over thousands to tens of thousands of years, not tens of years.

    The rapidity is the issue as much or more than the change itself. The speed means plants and animals can’t migrate to areas that are better suited to them climatically, let alone give time for evolutionary based adaptations.

    Will temperatures rise indefinitely and kill us all? Probably not.

    No it won’t kill us all well recognised.

    But it will and has killed many many people. Heat in the climate is energy, more energy is stronger winds and more violent storms. Changes in temperature is winds not blowing as they have for generations. It’s failed monsoons or rains when you expect and need it to be dry. It’s flash floods. It’s droughts. It’s also countries becoming poorer so people migrate it’s increased racial tensions it’s riots, it’s concentration camps.

    So, yes I agree it won’t kill us all but it’ll kill a fucking lot of us and a lot of the people it does kill will be the most valuable globally.

    Also

    the exact data we have to train those models is from the past 150-200 years.

    The word exact is doing some heavy fucking lifting in that sentence

    We have tens of thousands of years of ice core data and hundreds to thousands of years of tree ring data.
