Guest: Dr. Cumrun Vafa
Does the vast landscape of string vacua render the theory unpredictive, or can swampland conjectures and consistency conditions constrain physical possibilities?
Guest: Dr. David Gross
Why do quarks and gluons remain permanently confined within hadrons, and can analytical techniques complement lattice QCD in understanding non-perturbative dynamics?
Guest: Dr. Lisa Randall
Why is the observed vacuum energy density 120 orders of magnitude smaller than quantum field theory predicts, and can extra dimensions or modified gravity resolve this discrepancy?
Guest: Dr. GianCarlo Ghirardi
Can spontaneous localization models resolve the measurement problem without observer-dependent collapse, and do they make testable predictions distinguishing them from standard quantum mechanics?
Guest: Dr. Sacha Davidson
Do recent anomalies in muon g-2, B-meson decays, and other observables signal new physics beyond the Standard Model, or merely statistical fluctuations and underestimated uncertainties?
Guest: Dr. Kip Thorne
Can gravitational wave observations from merging black holes and neutron stars test general relativity in strong-field regimes and constrain alternative gravity theories?
