### .understanding

After Einstein’s Theory of General Relativity one would think we fully
understand gravity. Sadly, that is not the case. In fact we understand gravity
no more than Newton did. If anything, we understand it less.

Newton developed a simple equation and there was hope it would reveal the
mechanism behind the force. Then Einstein showed the effects of gravity to be
better modelled by the result of the interaction of matter with time and space.
While General Relativity allows us to calculate the effects of gravity with
more precision than we can measure, it gives us no more insight about the
mechanism of gravity than Newton’s theory did. Fundamentally, we don’t
understand gravity. If we did we’d know how to make gravity and anti-gravity,
but we don’t and so far we can’t.

So, having a theory that correctly models and predicts reality doesn’t mean we
understand it. In fact, we understand nearly nothing about gravity and nuclear
forces which means we understand nearly nothing about matter. We just know how
to model it really well. Keep this in mind when reading headlines about
breakthroughs in understanding of something. It usually just means we have
better, more accurate, equations.
