For nearly 150 years, geometers and other academics have been trying to imagine a mysterious fourth direction in space to account for the math of 4D geometry, but that abstract spatial axis has never been observed. Space remains three-dimensional.

However, representations of 4D polytopes can perfectly depict the motion of 3D objects through both space and time. A leading expert in the field has said they have not seen this view presented before.

The idea continues toward 5D geometry to represent what directly affects motion: force, comparing the 5D progression of a cube, a penteract, with events of cosmology and particle physics.

What da hell my eyes are doing but after many years and many different doctors I gave up, nobody ever saw nothing like that and can’t explain to me how my eye doing it…

The pink sky over Changzhou on 31 Aug 2026 near sunrise resulted from Rayleigh scattering. Low sun angle sent light through a longer atmospheric path, scattering blue wavelengths while red/pink dominated.

Approaching thunderstorm clouds, high humidity and particles intensified the effect for 7-8 minutes before heavy rain.

Brazilian scientist, Dr. Mariangela Hungria, spent 40 years perfecting bacteria that help crops access nitrogen while saving farmers billions each year.

Hungria developed biological treatments using beneficial soil bacteria that help crops access nitrogen from the air, reducing reliance on synthetic fertilizer. Her technology is used across tens of millions of hectares in Brazil. The World Food Prize estimates her work saves farmers about $25 billion annually and prevents roughly 230 million metric tons of CO₂-equivalent emissions.
