What is Time?

I have been thinking a lot about time recently.  I am fascinated by the concept of time as I've experienced the void where time does not exist.  And that is unfathomable to most of us as we have never not experienced time in our life; everything we do has a timestamp associated with it.  And when I hear people saying “I don’t have time,” I can’t help but wonder what time is and how it is a socially constructed concept.  My quest to understand time led me to the multiverse theory. 

In this multiverse theory, in layman’s terms, there is a static universe in the middle. From that, smaller universes pop off and travel in different directions, or arrows of time. And the Big Bang was one of these pop offs. It is this arrow of time that gives us the feeling of progress, the feeling of flowing or moving through time.  And because the arrow of time is one directional, we cannot go back to the past. The static universe in the middle has time as a coordinate but there's no arrow of time. There's no future versus past; everything is equal to each other. Time we perceive today started about 14 billion years ago after the Big Bang which marks the birth of the galaxy our solar system is part of.

Obviously the science behind this is far more complicated, so based on my limited understanding so far, I wonder if the void I experienced is the static universe and somehow our consciousness -- a neuronal energetic field -- can access that far place via the principles of quantum mechanics theory.  This potential connection between cosmology and consciousness is so fascinating to me.  The more I seek, the more remains mysterious while the more seem to converge.
