Formula Used in “Gravitational Time Dilation Calculator”
The formula for calculating gravitational time dilation is derived from Einstein’s theory of relativity. The standard formula can be expressed as:
Δt’ = Δt √(1 – (2GM)/(c²r))
Where:
- Δt’: Time interval experienced by an observer at a distance r from the mass.
- Δt: Time interval experienced by an observer far away from the mass.
- G: Gravitational constant (6.674 × 10⁻¹¹ m³ kg⁻¹ s⁻²).
- M: Mass of the object creating the gravitational field (in kilograms).
- c: Speed of light in a vacuum (approximately 3 × 10⁸ m/s).
- r: Distance from the center of the mass to the observer (in meters).
Step-by-Step Breakdown of the Formula
- Identify the variables: Gather the values for mass (M), distance (r), and use the constants G and c.
- Plug in the values: Substitute the known values into the gravitational time dilation formula.
- Calculate the fraction: Compute the term (2GM)/(c²r) first to prepare for the square root calculation.
- Subtract from 1: Perform the operation 1 – (2GM)/(c²r).
- Solve the square root: Take the square root of the result from the previous step.
- Multiply by Δt: Multiply the square root value by Δt to find Δt’ or the dilated time.
Example Calculation
Let’s calculate the gravitational time dilation for an observer near a black hole with a mass of 10 solar masses and at a distance of 10 kilometers from its center. We will assume that Δt, the time interval experienced far from the black hole, is 1 hour (3600 seconds).
| Variable | Value |
|---|---|
| M (Mass of Black Hole) | 10 × 1.989 × 10³⁰ kg (Mass of the Sun) |
| r (Distance) | 10,000 m (10 km) |
| Δt | 3600 seconds (1 hour) |
Now we can substitute these values into the formula:
Δt’ = Δt √(1 – (2GM)/(c²r))
Calculating the parameters:
- G: 6.674 × 10⁻¹¹ m³ kg⁻¹ s⁻²
- c: 3 × 10⁸ m/s
- M: 10 × 1.989 × 10³⁰ kg = 1.989 × 10³¹ kg
- r: 10,000 m
Now substituting into the formula:
Δt’ = 3600 √(1 – (2 × (6.674 × 10⁻¹¹) × (1.989 × 10³¹)) / ((3 × 10⁸)² × 10,000))
The final calculated values will yield Δt’, the time experienced by the observer near the black hole.
