General Relativity
Explore geodesic dynamics, black-hole length scales, and gravitational-wave estimates with interactive charts and stepwise outputs.
Use Cases
- - Compare characteristic black-hole radii for given mass scales
- - Estimate orbital periods in compact-object scenarios
- - Quick strain/frequency back-of-envelope wave checks
- - Educational walkthrough for GR approximations
Core Relations
- r_s = 2GM / c^2
- r_photon = 3GM / c^2
- f ~ sqrt(G(M1+M2)) / (pi*a^(3/2))
- h ~ 4(GMc)^(5/3)(pi f)^(2/3) / (c^4 d)
