Who is Brian Greene?

Humans cannot intercede in the lawful progression of their own particles, meaning actions are ultimately determined by physics.

“You do not have the capacity to intercede in the lawful progression of your particles.”

Protons are predicted to disintegrate at approximately 10^38 years into the future, effectively ending matter as we know it.

“By the 38th floor, wherever that is, we believe that protons, which are the heart of matter, will likely themselves disintegrate, fall apart.”

Brian Greene on his 20-year philosophical shift away from mathematics as the deep truth of reality.

“If you asked me that question 20 years ago, I would have given you one answer which would have been very combative and I would have been defending mathematics as like the deep truth of the world. In the past 20 years, I've shifted closer to your perspective. I really do see math as a powerful tool for describing the external world. I don't see it necessarily as the truth of what's out there.”

At approximately 10^11 years after the Big Bang, the Sun will swell to engulf Mercury, Venus, and possibly Earth, ending life on Earth.

“If you just go up to here, 10^ the 11 years, what happens here is the sun will get bigger and bigger. It swells. It eats up the close planets, Mercury and Venus. It may swallow up the Earth, too.”

A black hole with the mass of the Sun takes approximately 10^68 years to evaporate via Hawking radiation.

“A black hole the size of our sun with the mass of our sun about 10 the 68 years for that to happen.”

Brian Greene states with high confidence that free will does not exist.

“I do not think we have free will and I have high confidence in that assessment.”

At 10^50 years, the universe can no longer absorb the heat generated by thought itself, meaning any thinking being would incinerate upon thinking another thought.

“By the 50th floor, the universe won't be able to absorb the heat generated by the process of thought itself. So any thinking being when it thinks one more thought will burn up.”

Brian Greene reduces all human emotion to electrical impulses in the brain.

“I think that love and hate and anxiety and jealousy and gratitude and grief and all human emotion is nothing but electrical impulses going through our brains.”

Brian Greene argues string theory should be called 'the string hypothesis' because it has produced no testable predictions and does not yet meet the bar of a scientific theory.

“Maybe call it the string hypothesis.”

Brian Greene on ChatGPT reproducing months of string theory research in under an hour.

“Within a half an hour it was able to reproduce the results that took us months to get.”

Brian Greene rejects the many-worlds interpretation not on physics grounds but on philosophical ones: because he no longer believes mathematics is the fundamental truth of reality.

“I don't see it necessarily as the truth of what's out there, which is why I don't support the many worlds interpretation of quantum mechanics the way some of my colleagues do.”
