We fail in even the simplest of all scientific observations-nobody looks up anymore.

Trillions of years into the future, when all stars are gone...all parts of the cosmos will cool to the same temperature as the ever-cooling background. At that time, space travel will no longer provide refuge because even Hell will have frozen over. We may then declare that the universe has died-not with a bang, but with a whimper.

The good thing about science is that it's true whether or not you believe in it.

In modern times, if the sole measure of what’s out there flows from your five senses then a precarious life awaits you.

The idea that God resides in the unknown is what philosophers call the God of the gaps. And we have this thing called science, which marches on and makes discoveries in those gaps, ultimately closing gaps.

We already know the limits of Einstein's theories. From the centers of black holes at the very beginning of the universe - we call these singularities - Einstein's equations fail. In fact, people have joked that's where God is dividing by zero.
