With one hundred billion brain cells in the human brain, it is as the number of stars in the Milky Way - creating more connections than there are galaxies in the universe - governed by electromagnetism... physics

"Is there an independent reality or not? Imagine... The world around you is actually nothing more than an elaborate fabrication of some unknown superior intelligence. A giant super computer provides you with all your senses... But in fact you have no senses. Your body does not exist. You are just a brain in a jar... It doesn't actually matter... We think, therefore we are." (Stephen Hawking's Grand Design - The Simulation Theory)
"The hamburger could be nothing more than a piece of computer code but our desire to eat it is still our desire... There are fundamental limits to what we can know... It is much simpler to assume the table stays put when we are not there." (Stephen Hawking's Grand Design)
