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.
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 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.
That was great. :)
