@stux It's amazing how much distance there is between objects in space. I have to think of it in graduated steps: between us and the other planets, between our solar system and other stars, between our solar system and other galaxies. It's amazing how long it takes for our galaxy to make a single rotation.

How empty is space?
Very roughly: if the Sun were the size of a grain of table salt, the distance to Alpha Centauri, the nearest star, would be about four kilometers. Think about that. Can you imagine putting a single grain of salt down, walking four kilometers, looking back and being able to see it? But it gives off tremendous amounts of light, so we can.They cannot scare me with their empty spaces

Not to mention (and this is what always stops me in my tracks) we aren't at a standstill...all moving along, dragged behind a sun that is on it's own spiraling path, in an arm of a galaxy that is also moving through space.

@Sfwmson @kimlockhartga Awesome huh!
Nothing is "still"
It was such a revelation for me that the speed of light in a vacuum is one of the few constants we have
