No no you see it’s…it’s all made of vibrating… energy, no not like that, in a science way! There’s particles, but actually they’re waves, but of probability but its all energy. What is energy? Uh… work, over time. What’s work? Uh… the thing I really better get back to, bye!
its all energy. What is energy? Uh…
This. This so much. What the hell is energy and what enables it to exist?
Heat, movement, radiation, mass.
Heath
Not native language.
Sorry, I didn’t mean to criticize you, it’s just a joke.
It’s alright.
No heat, no radiation, no mass anymore, so heath is a vacuum?

What’s heat, precious?
energy is what scientists never have enough of and its existence is enabled purely by being able to observe yourself not having enough of it
Um… Uh… Entropy. What is Entropy? Uh…
As I recall it, energy is motion.
People always confuse multiple things.
There is gravity, the actual effect we see every day all around us. Gravity is a real thing, it exists. Then there’s the law of gravity, this is a math formula you can use to predict the effect gravity has on things. There’s multiple variations of this one, think Newton and Einstein. For almost everything the Newton version works just fine. Then there’s the theory of gravity, this is our attempt to explain why gravity exists and why it does the things it does. This is the tricky one we don’t really have a grip on.
By mixing these things it is often portrayed that “scientists” don’t know anything, they don’t even understand something as simple as gravity.
In addition, the word “theory” has a well known definition in the world of science. It also has a layman’s definition. Those two things are completely separate.
Yes very good point!
“That’s just a theory, a game theory!” won’t fly on your PhD defense.
I made a comment the other day saying pretty much the same thing about “respect” and “tolerance”. All three have multiple definitions that certain types of people, knowingly or unknowingly, use to their advantage to push an agenda. Generally the types of people I’m talking about are either evil (doing it purposefully) or very stupid (parroting others because they have no argument on their own) and in all cases they’re being shitty and think it means they win.
knowingly or unknowingly
Oh they know. Changing definitions is textbook propaganda.
We still don’t know how it happens. Only why.
And Newton’s formula doesn’t work for the solar system. And later ones not for galaxies (hence Dark
MatterUnicorn).I assume the “almost everything” is relative to the things people need to calculate gravity for. Astrophysics is cool, but rather the minority compared to, say, calculating the forces a bridge has to withstand or the arc of a ballistic projectile or any other calculations concerning primarily things on our planet.
In a way. I mean we know it exists, no one would reasonable deny it, but the exact mechanism are still debated. How much is beneficial adaptation, how much is genetic drift for example. But the common ancestry is as common sense as that an apple will fall to earth
Except that horizontal gene transfer happens.
Genes are not always gained from ancestors
bacteria and some others, preparing for horizontal gene transfer: “im about to ruin man(kind)'s whole career”
I thought it was pretty well accepted that it’s basically “Genetic defects happen, sometimes they don’t prevent reproduction and pass down to the next generation, then it’s a lottery, maybe it will last, maybe it won’t, maybe it’s beneficial, maybe it isn’t 🤷”
Maybe at some point a human was born with knees that would never wear out but they died before having the chance to reproduce from being eaten by a tiger, we’ll never know!
I audited a class on the topic. The professor said something like, “Some folks think evolution isn’t a fact, it’s just a theory — but they have it backwards! It is a fact…but it’s a lousy theory.”
I don’t get it
Me either
I think it’s because a proper theory needs a postulation of the cause of the phenomenon. We don’t have a single source on the cause of gravity or physical mechanism of evolution.
We have tons of evidence that it happened but our models for explaining and predicting it are bad at consistently and reliably explaining everything we’ve already seen, and each new discovery seems to break those models even more.
The theory is the model trying to explain how it works. The fact, though, is that we have evidence showing that it did happen, even if we don’t have a unified theory of how it happened.
Imagine a car crash site, where the cars have definitely crashed, but everyone has different debates about what caused the crash. Imagine further that the specifics of any person’s explanation has a few inconsistencies with what we see. So we’d have the fact that a car crash happened, but lousy theories explaining how it happened.
Probably meant we know that it happens and approximately how it happens, but the publicly communicated version is just vague enough to sound like hand-waving.
That was great. :)
Come on now. We all know that evolution is the expination to gravity! Look, all things that does not fall down, fall into space and die, hence only the things falling down to earth can live on and reproduce! Gravity is an emergent propery of evolution! Duh!
