We all think that the past is gone and the future is yet to happen. But Einstein had a different view. Check it out in our new installment of a Moment of Science with Brian Greene.

Some people may see that event A happened before event B, while other see that event B happened before event A. However, both people are experiencing the same "NOW" time. One persons clock may be ticking slower, and thus you think that this persons "NOW" extends" into the past behind him. However, I am sure you have seen many physics examples where you see that the clock at the rear end of a traveling object, is ahead of the one is located at the front of the object. So if you are at the front and look at the back end, you are also looking forward in time. These two phenomena cancel out and thus the "NOW" time is the same for both the traveler and the non-traveler.

Why does the camera keep moving around and zooming in and out?

But each observer will have their own time line from the past into the future their own Arrow of Time!

Well, yes, an absolute past, present and future are illusions. These in One referrence frames relative to others are also.

Even the arrow of time and velocity is in some sense dependent on the reference frames relative to wach other.

Three arrows of time :
1.The thermodynamic arrow of time
2.Physiological arrow of time
3.Cosmological arrow of time (expanding universe)

The way I best understand it is simply that past present and future are just relative terms we humans use to understand or differentiate events. Its all relative. Time however, scientific. The terms we used to describe it? Just relative

THIS NEEDS TO BE EXPANDED ON DON'T YOU THINK?

It hurts me deeply that Einstein did not live longer to discover more about time.

The arrow of time is only a human delusion. Time is just another dimension of spacetime
