What is Time? - AlwaysAsking.com
What is time? Few things are so familiar and mysterious. Time is the most common noun in the English language. Our lives are governed by time, and yet we have so little understanding of it.
In this episode, we consider what science has to tell us about time. We find that it is stranger than anyone could have imagined, at least, anyone before Einstein.
