A Question of Scale
Monday, May 16th, 2005I found a great gallery of images showing stuff at all scales, from “Quarks to Quasars”.
Excerpt from 1021: Given an estimated age for our solar system of 4.5 thousand million years, the Sun has made about 15 to 18 orbits around the galactic core.
Bruce Bryson writes: “This is a visual journey consisting of 42 images — 42 powers of ten. At one end of the journey is the immensity of the known universe, 13.7 billion years old with a radius of at least 12 billion light years (and probably much larger). At the other end of the journey is a depiction of the three quarks within a proton.”
