Sean M. Carroll: Frases em inglês

“Inflation is a simple idea: imagine that the universe begins in a tiny patch of space dominated by the potential energy of some scalar field, a kind of super-dense dark energy. This causes that patch to expand at a terrifically accelerated rate, smoothing out the density and diluting away any unwanted relics. Eventually the scalar field decays into ordinary matter and radiation, reheating the universe into a conventional Big Bang state, after which things proceed as normal.”

“All of my advice comes from remembering what I did wrong and then telling people not to do it. … Don't wait to read the most recent research papers. … Wonder how you could do better. … Do your own research projects. Take the initiative. … Ask your own questions — try to answer them. … At some point you stop being a student and you start being a scientist. … And it's a completely different skill set …”

“The mystery of the arrow of time comes down to this: Why were the conditions in the early universe set up in a particular way, in a configuration of low entropy that enabled all of the interesting and irreversible processes to come?”

“In contrast to the arbitrarily complicated evolution of a (nonintegrable) classical system, all a quantum state ever does is move in circles.”

“There probably are more forces than we know about, but they’re only going to be of direct interest to physicists, I’m afraid. No tractor beams.”

“The “reasons” and “causes” why things happen, in other words, aren’t fundamental; they are emergent. We need to dig in to the actual history of the universe to see why these concepts have emerged.”

Chap. 5 : Reasons Why
The Big Picture (2016)

“Metaphysical principles are tempting shortcuts but not reliable guides. There are good reasons why things often seem to happen for reasons—and also reasons why that’s not a bedrock principle.”

Chap. 5 : Reasons Why
The Big Picture (2016)

“What we’re seeing is a manifestation of the layered nature of our descriptions of reality. At the deepest level we currently know about, the basic notions are things like “spacetime,” “quantum fields,” “equations of motion,” and “interactions.””

No causes, whether material, formal, efficient, or final. But there are levels on top of that, where the vocabulary changes.

“Meaning in life can’t be reduced to simplistic mottos. In some number of years I will be dead; some memory of my time here on Earth may linger, but I won’t be around to savor it.”

The Big Picture (2016)

“When exactly does an observation occur? ... What were the laws of physics doing before there was anyone measuring things? And what do you mean by a measurement, anyway? Does it have to be a consciousness human being? ... Can a rock or a virus or an earthworm do an observation?”
