“How did the universe begin? What is the nature of time? Is space what it appears to be? If you absorb science’s most refined answers to such big questions, your perspective on reality will almost certainly shift. That we are a minor planet orbiting an average star formed in the aftermath of a stupendous swelling of primordial space is a realization that constantly informs my thoughts regarding how we fit into the grand picture. That time elapses at a different rate for me than it does for anyone else who is not moving precisely with me is a stunning fact that I reflect on endlessly.”
