String Theory & Extra Dimensions

Explore the fabric of reality at the Planck scale — vibrating strings, extra dimensions, brane worlds, holographic dualities, and supersymmetric partner particles.

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.

AdS/CFT Correspondence & Holographic Duality

Experience the holographic principle — watch how a gravitational theory in anti-de Sitter space maps to a conformal field theory on its boundary

simulator

Brane Worlds & Bulk Space

Navigate through higher-dimensional bulk space and observe how our universe may exist as a 3-brane floating in a larger dimensional reality

Extra Dimensions & Calabi-Yau Manifolds

Visualize the hidden dimensions of string theory — watch Calabi-Yau manifolds unfold and explore how extra dimensions shape the physics we observe

simulator

String Vibration Modes & Particle Spectrum

Watch fundamental strings vibrate in different modes and see how each vibration pattern corresponds to a different elementary particle in the Standard Model

simulator

Supersymmetry & Partner Particles

Explore supersymmetry by visualizing the boson-fermion partner spectrum — every known particle has a superpartner with different spin statistics
