The Hunt for Dark Matter

I was interviewed by Veritasium (Derek Muller) in his recent video on his hunt for dark matter. Check out the video here:

The Big Misconception about Electricity

A couple of months ago, I emailed a few people a little physics puzzle. Here's what I sketched and sent out. The result is that...

Misconceptions about the Universe

Another post from the past, this time from 2014 on confusion about the expansion of the universe. Over on youtube, Veritasium has a nice...

The One-Way Speed of Light - Again!

A little while ago I provided input to a video by Veritasium on the One-Way Speed of Light. You can watch the video here . This is not a...

The One-Way Speed of Light

How fast does light travel? Well, you might say the speed of light, but physicists have only ever measured the two-way speed of light,...

Do you expand with the Universe?

I chatted with Derek Muller at Veritasium about this very question, and he made this cool video. Check it out.

The Supernova that Measured the Universe

I spoke with Derek Muller about how you can use gravitational lensing time delays to measure the expansion of the universe. As usual,...
