The Logarithmic Spiral Gears is an extreme example of non-circular gear sets. It's based on the famous Fibonacci spiral and evokes the cross section of a nautilus shell with internal chambers

A tesseract is a four-dimensional hypercube, equivalent of a 3D cube, just as a cube extends from a 2D square. It has 16 vertices, 32 edges, 24 square faces, and 8 cube-shaped cells.

In 1985 an astronaut noticed this physical behavior of a handle, that turned out to be the proof of a theorem: the tennis racket theorem (also dubbed the Dzhanibekov effect).

🔴 In 1977, astronomers detected a one-time radio burst from deep space — the mysterious “Wow! signal.” It hit 1420 MHz, the key hydrogen line linked to the search for intelligent life. It appeared once… never again… and its source remains unknown. Nearly 50 years later, the mystery only grows. Now, hear the actual Wow signal for yourself.

The Sun is 99.8% of all mass in our solar system. Even if you somehow burned Jupiter and everything that is not the Sun in a fusion reactor, the Sun would still round up to 100% of all energy. The Sun is all that matters long-term.
