The universe is always in motion.
Physics is our way of asking why. Why do planets orbit, light bend, and tiny particles behave like waves? Start with the big ideas, then put one to the test.
One universe. Different scales.
No single model explains everything. Each theory is a lens, sharpened for a different part of nature.
Theories
Models turn observations into predictions. Explore scientific models and a developing hypothesis about geometry and spacetime.
Explore the research → 02 / Everyday scaleNewtonian physics
Forces change motion. From falling apples to soaring rockets, three laws describe the world we can touch.
Building in progress → 03 / Cosmic scaleRelativity
Space and time form one fabric. Mass curves it, light follows it, and motion changes how clocks tick.
Building in progress → 04 / Invisible scaleQuantum & electromagnetic
Fields carry energy; particles act like waves. Meet the strange rules beneath light, atoms, and charge.

Choose a launch angle and speed. Gravity handles the rest—no air resistance, just a beautifully simple arc.
? Try 45° first. On level ground, it gives the greatest range for a fixed launch speed.
