Schwarzschild Radius Pin

Schwarzschild Radius Pin

30 total reviews



The diameter of this pin is the same as a black hole with the mass of Earth.

If you compress any amount of mass, it becomes denser. If you compress it enough, it will become so dense that light can no longer escape it—this size is the object’s Schwarzschild radius. An object that is compressed smaller than this radius is a black hole.

If you compressed all of the mass of Earth into the diameter of this pin, it would be so incredibly dense that you would not even be able to see it.

Every object has a Schwarzschild radius proportional to its density: the Sun's is 3km, Jupiter’s is 2.62m, and a hamburger’s is smaller than a single atom. Karl Schwarzschild derived this property in 1915 using Einstein’s recent field equations.

    WE TAKE SCIENCE SERIOUSLY

    You deserve better than craft store science products. And we think learning is more impactful when you're holding a tangible piece of what you're learning about. That's why Stemcell exists.

    With every new product launch, our list of new ideas gets longer rather than shorter. So check in often for our latest projects, and thanks for being a part of our endeavor to make the world a smarter place to live.

    Believe in yourself; for everything else, there's science.
