  i know what gravity is, but i dont believe in it

  I’ve been reading a book about anti-gravity. I just can’t put this thing down.

  Gravity is caused by the fact that everything in the universe sucks.

    So what you are saying is micro black holes everywhere, thats genius!

  Gravity is just a side effect of the fundamental laziness of all things. Causality moves slower near mass, so it’s kind of relaxing to move towards it. That’s why everyone does it.

  PS: There is actually a SciShow Spacetime video about gravity being an emergent property instead of a fundamental force. And no I didn’t get this from ChatGPT, I’m just that dumb when it comes to advanced physics haha.

  I mean for 57k a year it doesn’t sound too bad tbh.

  I find it quite marvellous that the universe contains unexplainable stuff like this, actually.

  It is what make it risky to jump from the Burj Kalifa, at least on the last meter.

  source

  • match@pawb.social ⁨6⁩ ⁨hours⁩ ago

    And yet, jumping from the Burj Khalifa at 1m off the ground is not very dangerous, so it’s not the Burj Khalifa that’s doing it

    • dave@feddit.uk ⁨4⁩ ⁨hours⁩ ago

      And even if you jump from higher up, it’s the ground that does it, still not the Burj Khalifa.

      It’s not riky while you are falling from 800m, only at the end

  • nomecks@lemmy.wtf ⁨4⁩ ⁨hours⁩ ago

    Wouldn’t the strong nuclear force be what makes jumping from the Burj Khalifa dangerous? It’s not the fall that kills you, it’s the sudden stop.

  Gravity is what makes my feet hurt when I stand around too long without moving about.

  57k a year is a decent salary if you live in the UK.

  A seasoned postdoc could expect to make 55K max. A professor a bit more.

    57k€/year is a professional’s salary in Italy.

    Average is 32k€

    Well then I guess they don’t mean UK do they?

    57k usd is a little less than 42k gbp

    • porous_grey_matter@lemmy.ml ⁨10⁩ ⁨hours⁩ ago

      Which is roughly the pay for a staff scientist or lecturer

      source
  • porous_grey_matter@lemmy.ml ⁨10⁩ ⁨hours⁩ ago

    Postdocs are definitely not getting 55k in the UK except maybe if something like medicine is special? The range is like 36-45ish.

  Gravity is a fundamental force just like electromagnetism (supposedly)

  Fundamental means it cannot be explained by being caused by something else.

  But then they say gravity is an effect caused by spacetime curvature and electromagnetism is caused by quantum phenomena.

  What is the cause for spacetime or quantummechanics? Idk but somehow they don’t make it on the list of fundamental forces.

  Classical science, for all the good it did and does, is an unironic joke and if aliens knew about it they’d be laughing at us.

    Fundamental means it cannot be explained by being caused by something else.

    Fundamental force means we expect a carrier particle to explain it (for gravity that’s the Graviton, although it hasn’t been detected yet).

    electromagnetism is caused by quantum phenomena.

    Not even remotely true.

    What is the cause for spacetime or quantummechanics? Idk but somehow they don’t make it on the list of fundamental forces.

    Quantum mechanics is mostly that statistics is more complicated than we all thought . Seeking a cause for spacetime is interesting. It might be relevant to mention that there is a fundamental particle that imparts mass, which we call the Higgs Boson. I guess that could make mass and inertia something of a “fundamental force”.

      Maybe i am wording it wrong. I did make the comment half joking but my current understanding of how magnetism really works, which my physics teacher was unable to answer has a chapter on wikipedia called Quantum-mechanical origin of magnetism

      I have no degrees in this stuff though, i just think about them recreationally.

    I don’t think we know enough about quantum mechanics to even make a guess, yet. I do know that the reason we wanted to find the Higgs Boson so much was because we thought it could help explain how things acquire mass, which could lead to figuring out antigravity. But then we found it and it wasn’t doing what was originally thought. Or something.

  While reading this I had a sudden flash of inspiration in which I saw clearly exactly how gravity works, but then when I started typing I forgot again. It’s quite frustrating

  Gravity is not what makes your body limp. It would just heavily influence a limp body. PhD my ass.

  Gravity is the net effect of all electromagnetic forces and quantum fluctuations causing the smallest bits of information at the smallest scales to drift together over “time” due to black hole natural selection aka cosmic natural selection.

  It is the universe using math to reproduce.

  • fox@hexbear.net ⁨8⁩ ⁨hours⁩ ago

    That’s crank nonsense unless you’re able to describe it with quantum electrodynamical equations that also accurately define gravity, and the whole point is that we cannot reconcile gravity and quantum physics yet.
