[Eli5]:What’s the exact difference between time and space?
In: 2
It would be better if you gave context for your question.
Intuitively speaking, space measures where events happen. Time measures when events happen.
Speaking in physics (the tag you gave this question) space has three dimensions while time only has one. Space and time have different signs (+++- signature for the Minkowski metric used to model spacetime). You can actually view time’s relation to space under this metric as identical to the imaginary number’s relation to the real numbers. Note that physics (GR) is a mathematical theory and doesn’t really try to understand the nature of time directly, only for using time as an index to measure the universe.
