Meaning and Definition
The phenomenon where time appears to pass slower for an object in motion relative to an observer or in a stronger gravitational field, as per the theory of relativity.
In a non-technical sense, any perceived slowing or stretching of time, though this usage is rare.
Dialectal Variation
British vs American Usage
Differences
In British English, 'dilatation' may appear in medical contexts, but for physics, 'dilation' is preferred. In American English, 'dilation' is almost exclusively used.
Connotations
'Dilatation' can sound more formal or archaic; both terms refer to the same concept.
