Newtonian Time is a concept introduced by Sir Isaac Newton in the 17th century. It describes time as a constant and absolute measure that flows uniformly, independent of any events or observers. According to this view, time is the same for everyone, regardless of their location or motion. In Newtonian physics, time is treated as a separate dimension, allowing for straightforward calculations in mechanics. This perspective was foundational for classical mechanics, where time is a reliable backdrop against which events occur. However, later theories, such as Einstein's theory of relativity, challenged this notion by showing that time can vary based on speed and gravity.
