This is pretty incredible. Here's a to-scale model of EVERYTHING, from the tiniest particle that exists up to the size of the known universe. You can scroll backward and forward and see it all; there's the scaled size of a human, of a house, of Rhode Island, of Earth, of the Sun, of everything and beyond. I admit I actually got a whoosh of exhilaration by quickly scrolling out. It's awesome, and terrifying, and beyond informative. It definitively proves that you are nothing but a tiny speck in a colossal universe that you have no chance of ever comprehending. Happy Valentine's Day!
