007skaty Shadow Biosphere and Dark Matter
A shadow life is hiding in the dark (in the dark!) / A cosmic world that leaves no mark (yeah yeah!)
007skaty A three-dimensional Sphere passing through a flat plane appears to a two-dimensional Square as an expanding and shrinking circle.
007skaty Three-dimensional shadows help physicists theorize how interdimensional beings move through unseen directions
007skaty Trace the tangled cosmic threads to discover how interdimensional beings hide in plain sight.
Four-dimensional shadows: A 4D hypercube casts a 3D shadow that we can actually build, hold, and rotate in our three-dimensional world.
A measure of spatial extent, such as length, width, or height. In 1884, Edwin Abbott used a two-dimensional universe to explain spatial realms beyond our own.
