A journey through spacetime

Spacetime Curvature

Mass tells spacetime how to curve. Spacetime tells mass how to move. The grid beneath your scroll warps around each idea — a visual echo of Einstein's geometric theory of gravity.

G_μν + Λg_μν = 8πG/c⁴ · T_μν

Time Dilation

As you scroll deeper into the gravitational well of this page, time slows. The clock in the corner decelerates. Near a black hole, a second could span a millennium. Time is relative.

Δt' = Δt / √(1 - v²/c²)

Gravitational Lensing

Light bends around massive objects. Distant galaxies are stretched into arcs by foreground clusters. The universe is a lens, and spacetime is the glass through which everything is seen — distorted, magnified, revealed.

θ = 4GM / (c²b)

Event Horizon

Beyond the Schwarzschild radius, nothing returns. Not light, not information, not time itself. The quest ends here — at the boundary of the knowable universe, where relativity breaks and singularities begin.

r_s = 2GM/c²
