Ever wonder how big our planet would be if it was a black hole? You’ll wonder no more with the Black Hole Earth Schwarzschild Radius Replica. While the concept can be dizzying if you think too much about it, it’s truly fascinating. The more you compress objects into a smaller space, the more warped they become. So, imagine compressing everything on our planet—mountains and oceans included—into a 17.7 mm sphere. This concept is known as the Schwarzschild Radius and the 17.7 mm size would produce a black hole for the earth. The Black Hole is an exact tungsten replica of this 17.7mm sphere. And by exact, the creators mean exact. It’s the exact size of a black hole of Earth’s mass. Technically, Black Hole shows the event horizon of Earth as a black hole. But that’s just so you can actually see it. The use of tungsten is also deliberate as it’s almost as dense as humanly possible. Weighing 1.86 ounces, you can put the whole world right in your hand.
