Is time real? To answer this question, I shall first define what time is. Time is defined as a measured or measurable period, a continuum that lacks spatial dimensions. In the following paragraph, I shall discuss the meaning of time perceived and theorized by two of the greatest minds of human kind - Einstein and Kant. The aspects of time that we can understand are only based on what we can perceive, observe, and calculate.
Albert Einstein's theory of relativity came up with the idea that both space and time were relative to the observer, or the state of motion of the observer (Broadcast). Einstein's theory seemed to tell us was that, time is not absolute and universal. It can be changed by motion. Each observer carries around his own personal scale of time, and it does not entirely agree with anybody else's. There are two ways to understand time, first that it is path of gravitational physics, and quantum physics, tried to be explained in words understandable but Einstein and Newton has given different statements regarding time; Einstein said that time is relative and the more you approach the speed of light, time passes much slower. It is one of the most logical solutions to the problem while you are travelling at the speed of light holding a hand mirror, you could still see your reflection.
On the other hand Newton says that the bigger a body is faster over time, so the more you move away from Planet Earth or any celestial body slower time passes. Daily satellites clock has to be matched as time passes much slower "up there" and the satellites have a margin of error of 1 to 2 seconds. Steven Hawking has one of the most powerful brains and he has managed to find some common ground between theories as diverse as Einstein and Newton. In psychology, we learnt that there is a certain section in our brain (called V1 or V4) responsible for the perception of the motion of objects in our surroundings. This concept is related to what we are mentioning in the question (is time real?). Time is the sum concept distilled from and relative to the passing of the motion of objects and events in our minds. There is another area in our brain that is responsible for the perception for the "passing of moments". Time can be just like "Colour”; and colour is just an illusion, there is no such a thing, as colour, but it has certain part in our brain that reinterprets the strengths of the electromagnetic waves into Colours that so we "perceive" in our mind, but in nature there is no such thing as colour.
In physics, Einstein and Newton have both identified and utilized "Time" as a variable in their formulas, so I think time do exist in our existing universe. Wherever time is considered in actual formulas; it is done just to make things simpler. E.g. Speed=distance/time but speed can also be ...
