Powers of Time compliments the classic short film, Powers of Ten. Just as Powers of Ten is about spatial scale, Powers of Time is a journey in time. The journey slices time finer and finer, down to the tiniest sliver of time for which we have a name, the attosecond (10-18). Then we see a representation of ever-longer stretches of time, from a single second to over 31 billion years (or 10 18). A clever approach to a complex subject.
