    What do you mean no advances in the last 70 years?! In the last decade scientists detected gravity waves and imaged an actual real black hole. Also they’ve been steadily chipping at quantum gravity, give it a couple decades they’ll get there.

    unless we cancel all the funding

      Aren’t the first two things just experimental proves of Einsteins relativity theory from over 100 years ago?

      I don’t know about quantum gravity though.

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

        It came from the Labratory of The Mind, yes, the work was entirely metaphysical, but here’s the wierd part. They used that mental experimentation and applied it to real life action, and it worked. It’s like imagining you have a magic carpet for years then you stand on one and it starts flying. It began as imagination of the world around us, then when checked against reality. It works. Someone figured out that if something was passing around a sun. A planet, that it would dim the light at regular intervals. They checked, it did, that’s the only reason we know there’s planets outside our solar system. Someone checked the lumens of stars and found the data matched the theory. We use the color variations of stars in a similar way to detect more data. It’s quite remarkable. A recent discovery in gravity is that while gravity is a ‘‘constant’’, it actually fluctuates from place to place, I’m not sure if anyone figured out why yet, but if and when, how they find out, will be their imagining a reason, imagining how to check, checking in real life, and getting the data on if it’s right or not.

    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.

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

      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

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

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

    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.

    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
