Moondust Against Global Warming?

A group of scientists from the University of Utah has proposed that we collect dust from the moon and spray it into space near the first Earth-Sun Lagrange point, where it would linger for about two years and block about 2% of the sunlight that reaches us. While it would probably reduce the global average temperature, it would not remove carbon dioxide, which has its own negative effects, such as ocean acidification and shifting precipitation patterns. Similar plans have previously been put forward for giant mirrors in space, fleets of reflecting satellites, and earth-sized air conditioning units. We have a video coming up on this in a few weeks.

Why Do We Only Get Older and Not Younger?

Last year in September, shortly after the publication of my book “Existential Physics”, I did an interview for Big Think about some topics in the book. The one about entropy has now appeared on YouTube.

Chinese Researchers Create a Plastic-Metal

Plastics have taken over the world by being durable and easy to mold, but they make miserable conductors. This is sometimes desired, but sometimes not. A group of Chinese researchers have now found a way to attach nickel atoms to polymers to create a conductive plastic. Paper here, press release here. 

I have noticed that particle physicists try to pretend they don’t understand what my misgivings are all about. I can’t let them get away with that, can I? So in this week’s video I explain why they constantly make wrong predictions, and why it’s a problem.
