We reside on a random mote we call Earth orbiting an average sun in a galaxy that is one out of potentially trillions in an expanding universe.[1] The observable universe’s size is so huge it’s essentially an abstraction, something like ten to the power of 23 (1023) kilometers in diameter. About 13.8 billion years ago our universe was smaller than a millimeter in diameter when space and time began rushing outward faster than the speed of light to reach its current size.
