Final answer:
Time and space are interconnected in the four-dimensional fabric of space-time, where both are relative and affected by gravity and motion, as per Einstein's theory of relativity, rather than absolute and independent, as previously thought by Newton.
Step-by-step explanation:
The question 'How is time different from space?' can be approached by examining the nature of both space-time and relativity. Initially, Newton saw space and time as independent entities, but Einstein's theory of relativity changed our understanding by showing that both are interconnected and relative to the observer's frame of reference. Consequently, A) Time is linear, while space is three-dimensional is a traditional view but not complete. B) Time is a concept, while space is a physical dimension is not entirely accurate, as both are physical and conceptual. C) Time is continuous, while space is discrete doesn't align with modern physics. D) Time is relative, while space is absolute is contrary to Einstein’s relativity, where both time and space are relative.
Time, as defined in physics, is a measure of change and is impossible to know without something in the physical world altering. Spread across three dimensions, space defines an object's position. As per Einstein’s theory of relativity, the way an observer in a different gravitational field or moving at a different velocity measures time and space can significantly differ. In summary, while both concepts may seem distinct, especially when describing events, they are part of a four-dimensional fabric where both are influenced by relative motion and gravity.
