Utterly mind blowing. What I find astounding is it’s pretty much similar to atoms which are mostly empty space. That’s why they were saying when it comes to something like the Voyager 1 it probably will never get his by a comet, meteor or sucked into a planets gravitational pull because the universe is mostly empty space, so quite possibly that thing could be out there for billions of years which is unreal. But Mars, I never really visualized how far that planet is. Just imagine that when you were born you were placed in a car that left for Mars, a car that went a standard 70 mph on the highway. From the time you were born till now that car has been driving non stop 24/7 and you will only be halfway there when you reach 114 years old!

Yes indeed. Here’s a question which I’ve never gotten a satisfactory answer to...
If the speed of light in a vacuum is the constant c, and the vacuum of space is pretty much “lumpy emptiness”, IE, lots of nothing mixed with the occasional solar system or galaxy, and, at an atomic level the “space” inside matter is pretty much the same thing, how come the “nothingness” inside a chunk of glass does not act like a vacuum to a photon instead of making it slow down by some percentage of c ?
