What's New In The Universe

Direct Evidence Of Cosmic Inflation

Think about it this way: previously we thought that our universe was like a spherical balloon. In the new picture, it's like a balloon producing balloons, producing balloons. This is a big fractal. The Greeks were thinking about our universe as an ideal sphere, because this was the best image they had at their disposal. The 20th century idea is a fractal, the beauty of a fractal. Now, you have these fractals. We ask, how many different types of these elements of fractals are there, which are irreducible to each other? And the number will be exponentially large, and in the simplest models it is about 10 to the degree 10, to the degree 10, to the degree 7. It actually may be much more than that, even though nobody can see all of these universes at once.

Imagine the following scenario: You have two different tribes, your collectivist tribe over here—where everything's in common, and your individualist tribe over there. Imagine these tribes not only have different ways of cooperating, but they rally around different gods, different leaders, different holy texts that tell them how they should live—that you're not allowed to sing on Wednesdays in this group, and in this group over here, women are allowed to be herders, but in this group over there, they're not; different ways of life; different ways of organizing society. Imagine these societies existing separately, separated by a forest that burns down. The rains come, and then suddenly you have a nice lovely pasture, and both tribes move in.

Now the question is: How are they going to do this? We have different tribes that are cooperative in different ways. Are they going to be individualistic? Are they going to be collectivists? Are they going to pray to this god? Are they going to pray to that god? Are they going to be allowed to have assault weapons or not allowed to have assault weapons? That's the fundamental problem of the modern world—that basic morality solves the tragedy of the commons, but it doesn't solve what I call the "tragedy of common sense morality." Each moral tribe has its own sense of what's right or wrong—a sense of how people ought to get along with each other and treat each other—but the common senses of the different tribes are different. That's the fundamental and moral problem.

He studies the psychology and neuroscience of morality, focusing on the interplay between emotion and reasoning in moral decision-making. His broader interests cluster around the intersection of philosophy, psychology, and neuroscience. He is the author of Moral Tribes: Emotion, Reason, and the Gap Between Us and ThemJoshua D.

I think beyond me, beyond our individual silos, to achieve prosperity and development in a place like Sierra Leone does not involve giving free devices to victims, which leads to low self-efficacy and dependence on external actors; we need to make new minds. That involves giving young people the platform to innovate, to learn from making, and to learn, and to solve very tangible problems within their communities.

Feynman once told me, "Whatever you do—you're going to have to do crazy things to think about quantum gravity—but whatever you do, think about nature. If you think about the properties of a mathematical equation, you're doing mathematics and you're not going to get back to nature. Whatever you do, have a question that an experiment could resolve at the front of your thinking." So I always try to do that.
