Sean M. Carroll Quotes & Sayings

The asymmetry of time, the arrow that points from past to future, plays an unmistakable role in our everyday lives: it accounts for why we cannot turn an omelet into an egg, why ice cubes never spontaneously unmelt in a glass of water, and why we remember the past but not the future. And the origin of the asymmetry we experience can be traced all the way back to the orderliness of the universe near the big bang. Every time you break an egg, you are doing observational cosmology. — Sean M. Carroll

We are looking for a complete, coherent, and simple understanding of reality. Given what we know about the universe, there seems to be no reason to invoke God as part of this description. — Sean M. Carroll

The speed of time is 1 hour per hour, no matter what else is going on in the universe. — Sean M. Carroll

I don't want to give advice to people about their religious beliefs, but I do think that it's not smart to bet against the power of science to figure out the natural world. It used to be, a thousand years ago, that if you wanted to explain why the moon moved through the sky, you needed to invoke God. — Sean M. Carroll

I'm trying to understand how time works. And that's a huge question that has lots of different aspects to it. — Sean M. Carroll

God is not described in equations. — Sean M. Carroll

The fact that you can remember yesterday but not tomorrow is because of entropy. The fact that you're always born young and then you grow older, and not the other way around like Benjamin Button - it's all because of entropy. So I think that entropy is underappreciated as something that has a crucial role in how we go through life. — Sean M. Carroll

We seek an understanding of the laws of nature and of our particular universe in which everything makes sense to us. We do not want to be reduced to accepting the strange features of our universe as brute facts. — Sean M. Carroll

Just the idea that we, these little collections of atoms and molecules, are part of the world, but a part that can look at the rest of the world and figure it out in a self-referential way, is kind of breathtaking. — Sean M. Carroll

Scientifically speaking, the existence of God is an untenable hypothesis. It's not well-defined, it's completely unnecessary to fit the data, and it adds unhelpful layers of complexity without any corresponding increase in understanding. — Sean M. Carroll

I'm trying to understand cosmology, why the Big Bang had the properties it did. And it's interesting to think that connects directly to our kitchens and how we can make eggs, how we can remember one direction of time, why causes precede effects, why we are born young and grow older. It's all because of entropy increasing. — Sean M. Carroll

The particular aspect of time that I'm interested in is the arrow of time: the fact that the past is different from the future. We remember the past but we don't remember the future. There are irreversible processes. There are things that happen, like you turn an egg into an omelet, but you can't turn an omelet into an egg. — Sean M. Carroll

I'm a big believer that science is part of a larger cultural thing. Science is not all by itself. — Sean M. Carroll

Nothing in the fact that there was a first moment in time necessitates that an external something is required to bring the universe about at that moment. — Sean M. Carroll

A full understanding of what happens in our everyday lives needs to take into account what happened at the Big Bang. And not only is that intrinsically interesting and just kind of cool to think about, but it's also a mystery that is not given much attention by working scientists; it's a little bit underappreciated. — Sean M. Carroll

If our local, observable universe is embedded in a larger structure, a multiverse, then there's other places in this larger structure that have denizens in them that call their local environs the universe. And conditions in those other places could be very different. Or they could be pretty similar to what we have here. — Sean M. Carroll
