But lurking just behind the curtain of all these exotic phenomena is a deceptively simple idea that pulls the levers, shows how the pieces fit together, and lights the path ahead.
James Clerk Maxwell’s equations revealing the intimate connection between electric and magnetic fields looked very different in different frames of reference—whether an observer is moving or at rest.
Einstein connected the dots: The speed of light was a measurable manifestation of the symmetrical relationship between electric and magnetic fields—a more fundamental concept than space itself.
The concept of “at rest” — the static “empty space” invented by Isaac Newton—was unnecessary and nonsensical.
The faster you chase, the harder it is to go faster.
Resistance to change becomes infinite at the speed of light.
