Where does our arrow of time come from?

While I believe in all the known laws of physics, I see the idea of time as no more than a human construct having nothing to do with the laws of physics.

After all what we call time is simply relative movement of one object to another. We call one revolution of the earth around the sun a year. We call one rotation of the earth on its axis a day. We call one rotation of a secondhand on a clock a minute. These are all arbitrary human measurements of events We Humans call time. Thus in an endless universe time does not exist outside of the human mindset.

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
