Brian Greene's lecture prompted attendees to consider significant questions about theoretical physics, particularly regarding multiverse concepts and their connection to string theory. The impact of gravitational wave discoveries on our understanding of the universe was also a focal point, along with developments in the quest for a unified theory of physics. Attendees expressed interest in the holographic principle and its implications for space and time, as well as the role of mathematics in shaping theoretical frameworks. Concerns regarding the testability of string theory and its criticisms were discussed, alongside potential practical applications in technology and engineering. Overall, the discussion highlighted key areas of curiosity and ongoing exploration in theoretical physics.

I am trying to see if I can catch a lecture I just found out about today by Brian Greene. Does anyone have any good questions that they would want me to ask if I go there.

I went there it was very similar to the nova program and I didn't get a chance to ask him a question... there were so many people there that I had to watch it in a classroom over a live feed.
 


1. Can you explain the concept of multiverse and how it relates to string theory?

2. How do you think the discovery of gravitational waves has impacted our understanding of the universe?

3. Can you discuss the latest developments in the search for a unified theory of physics?

4. How does your research on string theory contribute to the field of quantum gravity?

5. Can you explain the concept of the holographic principle and its implications for our understanding of space and time?

6. What do you think is the most promising avenue for further exploration in the field of theoretical physics?

7. How do you envision the future of string theory and its potential impact on our understanding of the universe?

8. Can you discuss the role of mathematics in your research and how it has helped shape your theories?

9. How do you address criticisms that string theory is untestable and therefore not a valid scientific theory?

10. Can you discuss the potential practical applications of string theory in fields such as technology or engineering?
 
"Supernovae evidence for foundational change to cosmological models" https://arxiv.org/pdf/2412.15143 The paper claims: We compare the standard homogeneous cosmological model, i.e., spatially flat ΛCDM, and the timescape cosmology which invokes backreaction of inhomogeneities. Timescape, while statistically homogeneous and isotropic, departs from average Friedmann-Lemaître-Robertson-Walker evolution, and replaces dark energy by kinetic gravitational energy and its gradients, in explaining...
