Detailed explanation-1: -But it might humble you to know that all of those things – your friends, your office, your really big car, you yourself, and even everything in this incredible, vast Universe – are almost entirely, 99.9999999 percent empty space.
Detailed explanation-2: -It turns out that roughly 68% of the universe is dark energy. Dark matter makes up about 27%. The rest-everything on Earth, everything ever observed with all of our instruments, all normal matter-adds up to less than 5% of the universe.
Detailed explanation-3: -A hydrogen atom is about 99.9999999999996% empty space. Put another way, if a hydrogen atom were the size of the earth, the proton at its center would be about 200 meters (600 feet) across. While I wouldn’t want something that big landing on my head, it’s tiny compared to the size of the earth.
