The way science is taught to the masses is not unlike the way
religion is taught. The Church keeps it simple, nice neat stories
meant more to comfort, by providing a message that the world
is known and safe. They allow the curious to dig deeper, and
once in their fold, the true philosophy is revealed. What they've
been teaching is just a shadow, a simplified version, of what
they really believe.
Just one example, they still teach that gravity is a force at a distance
almost a century after that is not longer the belief. They still teach
that gravity always attracts, even at the college level, to this day.
A century from now, students will look back at the state of science
today and chuckle, as we laugh at those that feared sailing off
the edge of the Earth.
Never for a minute think 'they' have it all figured out. Not even
close. All the big discoveries are yet to come.
