Can We Really Get to Alpha Centauri? The Breakthrough Starshot Mission Explained

TL;DR

Billionaire Yuri Milner and physicist Stephen Hawking are leading a $100 million project called Breakthrough Starshot, aiming to send tiny lightsail spacecraft to Alpha Centauri at 20% the speed of light.

Transcript

In a previous episode, I said that traveling within the Solar System is hard enough, traveling to another star system in our lifetime is downright impossible. Many of you said it was the most depressing episode I’ve ever done . The distance to Pluto is, on average, about 40 astronomical units. That’s 40 times the distance from the Sun to the Earth....
