Time is a human invention, something that would not exist if humans did not exist. We think of time in two ways: time as dynamic and changing, or time as having temporal properties. The first concept of time is a contradiction. No event can be both past and present, or present and future, or past and future. Physical theories, especially those of special relativity, do not allow for an absolute ‘now’. ‘Is time real?’ introduces theories on time including the Growing Universe Theory, the Block Universe Theory, and the Phantom Time Hypothesis. What is the present? How long does it last? Is the future real?
