It Just Blows My Mind


“A single speck of dust is half way in size between an atom and the Earth.”
This statement has been going around the internet recently and I felt compelled to check it out.
Guess what? It’s true – basically.Image
To be closer to the truth, you’d have to say “A single speck of dust is half way in size between a subatomic particle and the Earth.”
So as large as Earth appears compared with a speck of dust, the dust is that much larger than a subatomic particle.
That’s pretty amazing. But, let’s pull it apart and take a better good look.
A subatomic particle is smaller than an atom and atoms are pretty darned small.
What subatomic particles are we thinking of?Image
If we’re thinking of a quark, that’s a particle that the protons and neutrons in the center of an atom are made of, then the statement would more accurately be:
A single speck of dust is half way in size between a quark and the planet Jupiter.
If we’re thinking neutrino, a tiny, tiny particle that results from radioactive decay, cosmic radiation or the fusion reactions inside the Sun, then the statement would more accurately be:
A single speck of dust is half way in size between a neutrino and the diameter of the solar system.
Really.
The next time you see a speck of dust lazily floating in the air….think about how huge it is compared to an atom.
It just blows my mind.
