    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

    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.

    This is wholly inaccurate. We do know what causes gravity; time dilation near matter (at least for smaller objects like the Earth). What we don’t know is why gravity, because we have yet to produce a model that matches both quantum effects and cosmic behaviors like gravity and dark matter/energy.

    “Quantum gravity” is the general term for what solution would describe something that ties these two universes of behavior together. The process of decoherence isn’t terribly well understood as far as carrying effects clear from particle scale to cosmic scale.

    Even then, some of the mathematical explanations from current models are plausible, but unproven.

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