Time News
Time is a fundamental concept that refers to the ongoing sequence of events from the past through the present to the future. It is a dimension in which events can be ordered from the past through the present into the future, and also the measure of durations of events or the intervals between them. Scientifically, time is typically measured according to the SI unit, the second, based on the properties of the cesium atom. Time is used to quantify, measure, and compare the duration of events or the intervals between them, and even sequence events. Theories in physics such as relativity have shown that time is not an absolute measure; it can vary according to factors like velocity and gravitational fields. Time’s precise nature and its relationship to space are studied within the framework of the theory of relativity and quantum mechanics, posing sophisticated questions about the continuum of space-time and the possibility of time travel.
