Black Hole Collision Calculator: Predict Merged Mass & Schwarzschild Radius

Calculate Post-Collision Black Hole Properties

Solar Masses (M☉)
Enter the mass of the first black hole in solar masses.
Solar Masses (M☉)
Enter the mass of the second black hole in solar masses.
Explore the hypothetical outcomes of black hole mergers with our Black Hole Collision Calculator. Input the masses of two black holes to predict the total mass and event horizon (Schwarzschild radius) of the resulting cosmic entity. Understand the incredible physics behind these extreme astrophysical events and the gravitational forces at play.

Formula:

Resulting Mass (Mnew) = M1 + M2
Schwarzschild Radius (Rs,new) = (2 * G * Mnew) / c2

Where:

  • M1: Mass of Black Hole 1 (in solar masses)
  • M2: Mass of Black Hole 2 (in solar masses)
  • G: Gravitational Constant (6.674 × 10-11 N(m/kg)2)
  • c: Speed of Light (2.998 × 108 m/s)
