Special relativity says nothing can travel through space faster than the speed of light. But space itself can do whatever the heck it wants, at least… - Lawrence M. Krauss

A truly open mind means forcing our imaginations to conform to the evidence of reality, and not vice versa, whether or not we like the implications.

More often than you might think, teaching science is inseparable from teaching doubt.

the universe is big and old and, as a result, rare events happen all the time. Go out some night into the woods or desert where you can see stars and hold up your hand to the sky, making a tiny circle between your thumb and forefinger about the size of a dime. Hold it up to a dark patch of the sky where there are no visible stars. In that dark patch, with a large enough telescope of the type we now have in service today, you could discern perhaps 100,000 galaxies, each containing billions of stars. Since supernovae explode once per hundred years per, with 100,000 galaxies in view, you should expect to see, on average, about three stars explode on a given night.
