There seem to be two major theories currently.
The theory that the vast majority of people have naturally come to accept because it's the most sensible from a simplified and personal perspective is that time is constantly flowing in all places continuously ― beginning to end.
The less known and accepted theory is that every point in time exists simultaneously. To understand this, one can compare the universe to a DVD, Blu-Ray, etc. Any and all points within the movie exist on that disc simultaneously. It's simply a matter or rewinding or fast-forwarding to reach that point, and yet it moves in a coherent path on its own.
What is your view on the subject?

I wouldn't call it an illusion. It's a very real thing, but I think there are just different perspectives of time and it's effects. It may be a byproduct of other things, but in my mind, it doesn't make sense to say that time [i]doesn't exist.[/i] Gravitational lensing is enough for me to believe that time is a real thing. There is Eddington's arrow of time, which basically uses entropy to explain what time is. Makes a lot of sense, doesn't need to much explanation. Entropy (amount of unavailable energy) increases, time passes forward, and vice versa. There is the 4 dimensional interpretation of the universe, as explained through relativity, where time exists as a real thing just as space does, intertwined into spacetime. This explains many phenomena in the universe for us, and has gave way to many advances in astronomy. However this isn't the definite explanation of what time is because it shows us what time [i]does.[/i] But I guess you can say that if we see what it does, then it must be real. Then there is the hypothesis that time is a byproduct of quantum entanglement. I'm no quantum physicist, so I won't even try explaining something I hardly understand myself, but do remember seeing an experiment done specifically on this subject in the past couple years, so a quick google search will probably provide you with relevant and better information that I can.
