ALT A journey from the smallest to the biggest things in the cosmos: At the smallest level, String Theory proposes that all matter is made of minuscule, vibrating strands of energy — shaping the fundamental particles and forces that govern reality. Atoms, molecules, and cells build up the structure of life, which in turn resides on planets orbiting stars. Stars are nested within vast galaxies that form the visible architecture of the cosmos. Yet even galaxies are just part of something bigger. Galaxies group into superclusters, which are woven into immense cosmic webs stretching across the universe. And beyond that? Some theories suggest our universe may be just one in a multiverse — a collection of countless universes, each potentially with its own laws of physics. From quantum fields to galactic superstructures, every layer we peel back reveals an even grander one, reminding us how vast — and layered — reality truly is. Image: From Quarks to Quasars
