This is one of our universe's greatest enigmas. Time is not something you can point to, it has no form, it has no mass, but it is one of the most abstract concepts. When we look at the moon (!!), we see the moon as it was 1.3 seconds ago (for us). The fact that it is called a landscape is one of the best descriptions. I myself think that all things, such as certain sub-atomic particles) that themselves have NO mass, "live" in the same time frequency and all particles that DO have mass, are relative to each other ... By thinking about this you enter the deepest recesses of your brain and your soul.
