What is Schwarzschild Radius
The Schwarzschild radius represents the radius of the event horizon of a non-rotating black hole – the boundary beyond which nothing, not even light, can escape the black hole’s gravitational pull. This radius depends solely on the mass of the black hole and is calculated using Einstein’s theory of general relativity. For any object compressed within its Schwarzschild radius, it will inevitably form a black hole.
How to Calculate Schwarzschild Radius
Step 1: Enter the mass of your object or black hole in either kilograms or solar masses. For reference, our Sun’s mass is 1 solar mass.
Step 2: Select the appropriate mass unit from the dropdown menu. Choose between kilograms (kg) for smaller masses or solar masses (M☉) for astronomical objects.
Step 3: Click the calculate button to obtain both the Schwarzschild radius and the surface gravity at the event horizon.
Step 4: Review the results, which will show you the Schwarzschild radius in appropriate units (kilometers, meters, or millimeters) and the surface gravity in meters per second squared.
Step 5: Examine the explanation section below the results to understand how these values were calculated using the fundamental equations of black hole physics.
Step 6: For astronomical objects, consider using solar masses as your input unit, as this is the standard unit used in astrophysics for massive objects like black holes.
