‘The deviations were there way before that… That’s what makes this so cool.’ Ed Copeland explains Cosmic Microwave Background Radiation and the Planck results
Still wondering exactly why Planck’s speckled-egg pictures are so wonderful? Here’s a typically relaxed and clear explanation by Ed Copeland of what they tell us about events 380,000 years after the big bang, and what that tells us about even earlier times. And in 17 minutes, you will understand as much about inflatons as I do.
So there you have it. And if you want to know how it all relates to the particle physics, you couldn’t do a lot worse than watch this.
