Final answer:
Time dilation is a phenomenon in physics where time does not always progress at a uniform rate. It has been observed in various experiments and is an intrinsic property of time itself. Time dilation occurs when clocks that are in relative motion run more slowly compared to stationary clocks.
Step-by-step explanation:
Time dilation is a phenomenon in physics where time does not always progress at a uniform rate. This effect has been observed in various experiments, including the use of atomic clocks in different locations and even in space.
Time dilation occurs when objects are in relative motion, causing clocks that are moving to run more slowly compared to clocks that are stationary. This phenomenon is an intrinsic property of time itself and is not caused by inaccurate clocks or measurements.
Other scientists have challenged the concept that time progresses in a strictly linear and uniform manner, as represented by conventional clocks. Insights from physics, particularly the theory of relativity as developed by Einstein, have revealed that time dilation is an intrinsic property of time itself, and that elapsed time is not the same for different observers if they are in relative motion to each other.
Experiments have confirmed that biological clocks, atomic clocks, and indeed all clocks moving relative to an observer, display varying rates when measured against a stationary clock. These variations are influenced by factors such as gravity and velocity.
