Growing up you believe the world is meant to be the way it is. The older I get the more I realise that this is not the case. The world is full of injustices and atrocities that governments and the voice of faith expect us to accept, though with each passing year they grow fewer and fewer, at least one would hope. I have created this blog as a space for me to rant about all things science, politics, philosophy and religion, before it’s too late and the vessel of new atheism propelled by a growing surge in secularism solves all of the world’s problems for good.

The Richat Structure

This amazing piece of geology is found in Oudane, in the Sahara desert of Mauritania. It's about 50km in diameter and up to 450m above sea level. According to NASA...
Initially interpreted as a meteorite impact structure because of its high degree of circularity, it is now thought to be a symmetrical uplift (circular anticline or dome) that has been laid bare by erosionPaleozoicquartzites form the resistant beds outlining the structure. The lack of shock metamorphism at the site further backs the latter claim.
