Time is a way we try to make sense of events. To most of us, time seems to be a sequence from present to future, though some mental illnesses cause some people to mix it up. It's not unique to humans to experience time, dogs can smell the passage of time. Speaking of dogs, their eyes register images faster than our eyes, does that mean they can see the future, by our perspective of time?

Despite what science fiction writers and other forward thinking people believe, time travel is not possible for the simple fact that time is a human construct, and as such, our notion of time has no meaning in the grand scheme of things.

As an example, no one knows exactly how long a second is, because we base our measure of time on how long it takes the sun to go from east to west. Unbeknownst to us, over the course of its history, the earth's rotational speed has actually slowed, so that original "standard" is no longer useful.

We use atomic clocks that are based on highly precise oscillators, but we still don't know how long a second is because there is no naturally occurring standard for measuring something that exists only in the minds of human beings.

Our perception of time is a human construct, but it does exist. It is like saying their is not two objects on the table over there, because man invented the number two.
