Gravity was invented by Isaac Newton because he was invested in an airline.
That’s the real answer. Always check on whose payroll somebody is.
I’ve been reading a book about anti-gravity. I just can’t put this thing down.
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.

Just had to fucking jinx it didn’t you
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 wouldn’t say “just”, experimental proof seems huge.
But if you want theories just go to PBS space time and open anything that isnt string theory or mond.
i say do watch the ones about string theory and mond so you can see why/how they’re wrong
As a layman who’s into physics it took me like a decade to understand what is “wrong” with them. No educational string theory video is prefaced with “Hey this is an old unprovable theory that is essentially dead in the water, but it has some cool math tricks and is fun to think about” as they should be.
PBS Spacetime’s approach was a pair of videos titled “Why String Theory is True” and “Why String Theory is False” and between them that pretty much put it to bed for me. cool math, cool worldbuilding, call me when they make a testable prediction. until then it goes on the scrap pile with aether and phlogiston.
Gravity is caused by the fact that everything in the universe sucks.
And here I thought it was just your mom
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.
Oh hell yeah I love an emergent property. That’s my new favorite theory
The far end might sound smart to you if you’ve never taken physics classes, but…
Mass go brrrr
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€
With 57k€ you can afford to live comfortably, even get yourself a roomy flat, which is unusual for single individuals.
*Exceptions may apply, see Milan or other big cities
Postdocs are definitely not getting 55k in the UK except maybe if something like medicine is special? The range is like 36-45ish.
55k dollars in the US gets you a crappy apartment and a 7 year car loan.
57k usd is a little less than 42k gbp
Which is roughly the pay for a staff scientist or lecturer
That is not a decent salary, that is so low. I made almost that much just out of college in the U.S. Once I made it just over 10 years as EE, I was double that.
in the uk
is the important part. you would be considered a high earner earning that
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.
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
Congratulations, here’s your PhD
I find it quite marvellous that the universe contains unexplainable stuff like this, actually.
There is an actual logical proof that there are propositions in mathematics that are neither provable nor refutable.
Gravity is what makes my feet hurt when I stand around too long without moving about.
No, it’s pain receptors
Gravity is pain receptors. Got it.
We’re unlearning a lot today.
It is what make it risky to jump from the Burj Kalifa, at least on the last meter.
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.
