Some Stuff to Think About

Source: Halliday Resnick & Walker, Fundamental of Physics, Sixth Edition
Let's remember:
Our Earth is not the center of the Solar System
Our Sun is but one star among many in our Galaxy.
Our Galaxy is but one of many, and our Sun is an insignificant star in it.
Our Earth has existed for perhaps only a third of the age of the universe and will surely disappear when our Sun burns up its fuel and becomes a red giant.
Our species has inhabited Earth for less than 3 million years, a blink in cosmological time
But guess what?
All the laws of physics that taught us this stuff tell us this:
The laws of physics hold, as far as we know, throughout the known universe.
And the laws of physics were uncovered on Earth. And much remains to be discovered.
The universe is full of magical things, patiently waiting for our wits to grow sharper.
