We can replicate it. Get some mass, put it in one place; there, gravity. And, also, we can really
explain it. It's explained by the
interchange of massless virtual spin-2 bosons. (Well, only perturbatively, of course, nonperturbatively it's described by the obvious UV-completion.)
I mean, really, I can tell you how the universe literally started
using this theory, and with it can calculate, measurably correctly, the
relative abundances of all the atoms in the entire universe
. What more do you want from us?
That's like claiming no one really
knows how to build castles, they're just a theory

castle, because it's not your
There is so much we DON'T know
Some of us, more than others.
to say something is not possible or cannot work is the most retarded, arrogant attitude imaginable.
Let me try: In chess, through legal moves, it is absolutely impossible
for a white bishop who starts on a white square to ever end up on a
black one. A scandalous claim, indeed!
Gravity holds everything down no matter the size, yet it is with thoughtless ease that i defy gravity everytime I move any part of my body upwards.
You mean ironic
And so I have pondered and pondered... What is gravity.. What is magnetism.. How does the earth spin perpetually? The other planets? How is it all
And yet, you do not know the difference between a covariant and contravariant vector field, or how to parallel transport one, or how to solve the
It's almost as if pondering
were two very different things, one, vastly more difficult than the other.
So I ask myself, in an overly philosophically ponderous, breathy, voice whyyyyyy????
