String theory proposes that the fundamental constituents of nature are not point particles but tiny one-dimensional vibrating strings. Different vibrational modes of these strings correspond to different particles — electrons, quarks, photons, and even gravitons. The theory requires extra spatial dimensions beyond the three we observe, curled up into intricate Calabi-Yau manifolds at scales far smaller than any current experiment can probe.
These simulations let you explore the key ideas of string theory visually. Unfold extra dimensions, watch strings vibrate into the particle spectrum, navigate brane worlds floating in bulk space, experience the holographic principle through AdS/CFT correspondence, and discover the supersymmetric partners predicted by the theory.
