Ideas How mind-bending theories could solve mysteries in physics
Nov 4, 2025
Join theoretical physicists Sarah Shandera and Savas Dimopoulos as they dive into cosmic mysteries. Shandera discusses the importance of data and new mathematical frameworks in cosmology, highlighting the capabilities of cutting-edge observatories like JWST. Dimopoulos explores mind-boggling concepts like extra dimensions and the implications of a multiverse, suggesting they could explain the cosmological constant. Together, they tackle fundamental questions about dark matter and gravity's peculiarities, offering fresh perspectives on the universe's complexities.

Episode notes
Math Plus Experiment Unlocks Nature
- Mathematics and experiment are complementary tools that together let us derive and verify physical laws with astonishing precision.
- Savas Dimopoulos highlights that theory must bow to experiment, citing Feynman: beautiful ideas fail if data disagrees.
Where The Standard Model Falls Short
- The Standard Model explains vast phenomena with about 20 particles and parameters, yet fails to account for dark matter and the cosmological constant.
- Dimopoulos frames the cosmological constant and hierarchy problems as central puzzles motivating new theories.
Test Extra Dimensions Experimentally
- Consider extra dimensions as a mechanism to dilute gravity and explain its weakness compared to other forces.
- Dimopoulos suggests searching for missing-energy collider signatures and small-scale experiments for evidence.
