Explore motion under gravity with an interactive simulator. Change g, mass, initial height and velocity, and try different worlds (Moon, Earth, Mars, Jupiter).

Interactive Rutherford scattering: α-particles, gold foil, and a tiny nucleus. Adjust Z, energy, and emission rate to see passing, scattered, and backscattered counts.

Interactive special relativity simulator: moving spaceship and clocks. Adjust v/c to see time dilation (moving clock ticks slower) and length contraction. Formulas γ, Δt = γ Δτ, L = L₀/γ.

Interactive general relativity demo: rubber-sheet spacetime and light bending. Adjust mass strength and impact parameter to see curvature and geodesic deflection. Formula α ≈ 4GM/(c²b).

Interactive black hole simulator: event horizon, bent light rays, and gravitational time dilation. Adjust mass and impact parameter; see r_s = 2GM/c² and time slowing near the horizon.

Interactive wormhole simulator: 2D space folded into a tunnel. See shortcuts through spacetime and why wormholes are unstable. Adjust throat radius, curvature, and stability.

Interactive time travel demo: closed timelike curves (CTCs), timeline splitting, and why paradoxes arise. Compare physics-allowed CTCs with Sci-Fi paradox zones. Adjust CTC strength, branches, and loop extent.

Interactive double slit simulator: particles gradually form an interference pattern on the screen. Adjust wavelength, slit separation, and screen distance to see wave-particle duality and fringe spacing.

Interactive quantum superposition simulator: probability clouds for two overlapping states (Schrödinger's cat style). Adjust |α|², phase, spread, and separation to see interference and how measurement collapses the wave.

Interactive quantum entanglement simulator: two particles in a singlet state reacting together no matter the distance. Measure one and see the other correlate instantly. Adjust separation, correlation strength, and measurement angles.

Interactive quantum tunneling simulator: particles passing through an energy barrier when E < V₀. See probability leak-through in real time. Adjust energy ratio, barrier width, and mass to observe how transmission probability T changes.

Interactive wave function collapse simulator: fuzzy probability distribution before measurement, sharp outcome after. Adjust P(A), spread, and peak separation; click Measure to see collapse. Measurement changes outcome.
