The ages of things: understanding what is true

This post is as much for my benefit as it is anything else.  I’ve spent a couple of hours over the last few days piecing together the various ages of things that I think are pretty darn awesome.  Estimates here are of course based on the latest science as far as I could determine, so being based on good science, they are subject to adjustment with better evidence.


Please comment below if you see any mistakes or updates that need to be made. Also let me know if there are some really cool events that I may have missed that you think deserve to be on the timeline.
