Why Elon Musk believes we could colonize the entire galaxy in a million years To Elon Musk, it's not even a hard question. A million years is enough to spread across the whole galaxy. So where is everyone? Nobody seems to have done it. Something stops civilizations before they get out there. That's the great filter. And it's why he thinks about Mars with one specific test. Elon: "Do we have enough resources on Mars such that if the spaceships from Earth stopped coming, you can survive?" Joe Rogan compared it to a long sea voyage where the only thing you're missing is vitamin C. And the ships could stop for reasons that aren't dramatic at all. Civilization on Earth could end with a bang or a whimper. A Mars that can survive on its own is how he thinks we get past the filter.

Elon Musk explains why you should never charge an electric car to 100% The last 20% is not a small ask. Elon: "getting from 80 to 100, it takes about as much time as getting from 0 to 80" It runs backwards from how people fuel a car. Elon: "it's a little counterintuitive, because for a gasoline car you would fill it up" Inside the battery, ions are looking for somewhere to go. Elon: "the lithium ions are trying to find a parking space" Elon: "when the parking lot's empty, they can zip right in there and find a spot, it's easy" Elon: "as the parking lot gets full, just like trying to find a parking space at a mall, you have to hunt around for a spot" So on a road trip the rule flips. Elon: "you actually want to charge to about 80%, and then run it down all the way to 10%, or less"
