Cosmology is the scientific study of the origin, evolution, and ultimate fate of the universe. From Hubble's discovery of cosmic expansion to the detection of the cosmic microwave background, observations have transformed our understanding of space and time. The standard ΛCDM model weaves together general relativity, particle physics, and thermodynamics into a coherent narrative spanning 13.8 billion years.
These simulations let you explore the key pillars of modern cosmology: measure galactic recession with Hubble's law, decode the CMB power spectrum, quantify dark energy's accelerating push, trace primordial element formation in the first minutes, and visualize the exponential expansion of cosmic inflation — all with interactive, physically grounded calculations.
