The title refers to an excellent series of you tube videos by potholer54 (a science journalist based here in Australia), which gives a concise account on what science tells us about the history of the universe, from the Big Bang, to the formation of the Earth, to the origins of life, to the origins of humans. The videos are really well done, and do an excellent job of conveying not just what we know about these topics, but also how we know it.

Below is part 1.

I came across this via another series by potholer54 which is on the science of climate change which was featured in this post at Greenfyre’s.
