Atomic clocks prove relativity through experiments like the Hafele-Keating experiment. Clocks flown on planes show different times compared to those on the ground, demonstrating both special relativity (time dilation due to speed) and general relativity (time affected by gravity). These precise measurements confirm Einstein’s theories and are essential for technologies like GPS that require extreme accuracy.

FAQs & Answers

  1. What is time dilation? Time dilation is the difference in elapsed time experienced by observers moving relative to each other or situated in different gravitational fields.
  2. What is the Hafele-Keating experiment? The Hafele-Keating experiment demonstrated the effects of time dilation by comparing atomic clocks flown on planes to those left on the ground.
  3. How do atomic clocks work? Atomic clocks operate based on the vibrations of atoms, typically cesium or rubidium, providing extremely precise timekeeping.
  4. How does relativity affect GPS technology? GPS technology accounts for time dilation due to both speed and gravity to ensure accurate positioning, reflecting principles of both special and general relativity.
