How to Use This Calculator

This time dilation calculator lets you enter a distance in light-years and acceleration in m/s² to see how time dilation affects your journey. It shows differences between traveler and observer times, maximum velocity, energy requirements, Doppler shift, Lorentz factor, and how distances vary between reference frames. Charts appear after you calculate.

Results

  • Traveler's Time: How much time the person on the spaceship experiences
  • Observer's Time: How much time passes on Earth during the journey
  • Maximum Velocity: The highest speed reached, as a fraction of light speed

What is Time Dilation?

Time dilation is an effect from Einstein's theory of special relativity. The faster you move, the slower time passes for you compared to someone standing still. At 90% of light speed, time passes about 2.3 times slower for the traveler than for someone on Earth.

What is the Time Dilation Formula?

The Time Dilation Formula is:

t' = t / √(1 - v²/c²)

Where:
t' = time measured by the observer (on Earth)
t = time experienced by the traveler
v = velocity of the traveler
c = speed of light (299,792,458 meters per second)
