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
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.
The far end might sound smart to you if you’ve never taken physics classes, but…
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.
Gravity is how attracted I am to your mother
Babe wake up new physics copypasta just dropped
Gravity is the opposite of comedy.
Lemmy: Hey, remember how reddit used to be so good?
Satan: Yeah! Dang, I miss those days.
Lemmy: I’ve got tons of what you don’t miss about reddit and little of what you do!
Satan: Hooray!
Gravity is caused by the fact that everything in the universe sucks.
So what you are saying is micro black holes everywhere, thats genius!
And here I thought it was just your mom
I’ve been reading a book about anti-gravity. I just can’t put this thing down.
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.
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
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
57k usd is a little less than 42k gbp
Which is roughly the pay for a staff scientist or lecturer
Well then I guess they don’t mean UK do they?
If you think my comment was vacuous, you should see the ones that replied to it
55k dollars in the US gets you a crappy apartment and a 7 year car loan.
you dont even need a phd to get that 55k salary, might as well not go to grad school.
Can confirm
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 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.
It’s not riky while you are falling from 800m, only at the end
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.
I find it quite marvellous that the universe contains unexplainable stuff like this, actually.
Everything we know about all space and time is technically just entirely made up by us.
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.
And now we have direct photographs of planets around other stars.
Made up, and then confirmed with experimentation against actual reality.
Let’s not pretend science is literature with extra steps. It’s a process whos aim is to confirm things in a way that removes all possible alternative explanation or influence. A good experiment completely and fully removes the human element.
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
