Fundamental Physics and the Fifth Dimension ▸ KITP Public Lecture by Raman Sundrum

The juncture of elementary particle physics, cosmology and gravitational wave research, the beauty of the fundamental laws of Nature as well as some remaining mysteries are ripe for experimental exploration. The question of whether the Higgs boson is elementary, or a composite of other constituents, may lie at the root of these mysteries. Higgs compositeness is a notoriously thorny paradigm to model directly, but it can be understood more readily in a “geometrized” form, framed in a higher-dimensional “warped” spacetime. This physics can be, and is being, searched for experimentally, and it could provide a stepping stone to yet further discoveries.
Raman Sundrum is the John S. Toll Chair and Distinguished University Professor of Physics at the University of Maryland, College Park. He is currently the Director of the Maryland Center for Fundamental Physics. Sundrum is a theoretical particle physicist, primarily working on the structure of the fundamental forces of Nature and their connections to possible extensions of Relativistic Spacetime, such as Supersymmetry and Extra Dimensions. He also studies their possible roles in the very early Universe. His focus is on uncovering new mechanisms at the intersection of Quantum Mechanics and Relativity. Sundrum’s research provides theoretical templates for a broad range of experiments, from searches for new particles at the CERN Laboratory's Large Hadron Collider to precision cosmological measurements.
Sundrum has been awarded Fellowships of the American Physical Society (APS) as well as the American Association for the Advancement of Science, and is the winner of the Department of Energy’s Junior Investigator Award. This year, he was co-winner of the APS's J.J. Sakurai Prize for Theoretical Particle Physics.

This was the first public lecture that actually made any sense talking about higher dimensions. Thank you

[@zackbarkley7593]

Dear Dr Sundrum thank you for the great publicly accessible lecture! Can you (or viewers), provide a good maths primary reference/review of the Kaluza Klein type theories theories you discuss with regard to particle physics...in particular with regard to deriving massless EM and low W Z masses relative to Planck mass using the slightly oblate spheroid internal group...if its published?

47:00 : We already have a mechanism for scale invariance though! Why do we need a new one? The one we have is given by Einstein and general relativity, the contraction of space and dilation of time near concentrated mass.

[@rebeccaerb9935]

Interesting!

Stop lying

It's possible to go faster than speed of light! We just don't know at this time.

[@ht6395]

I think we definitely do its just hidden from us

[@leaf3571]

look into quantum entanglement

[@pathfinder1965]

The sage of six paths gave me his powers I'm faster than light now

[@oxnard_audit9923]

Simply make light go faster than normal light by increasing its magnification. This isn't rocket science

My problem is that it’s al theorists. Math is a weird way to try to summarize something we don’t truly understand.

Time is composed like music. Gravity/orbit allows for beats. The spirit shapes and controls the instrument of "lived time," and the spirit's will operates within the 5th dimension of possibility.

[@Jaantoenen]

Gravity bobs.
