“Space may not be what it seems. And neither, perhaps, is the universe.”
We grow up assuming that space has three dimensions because that is what our senses insist upon. Yet modern physics has long entertained a far stranger possibility: that additional dimensions may exist, hidden from everyday perception but deeply woven into the fabric of reality. This lecture introduces the idea of extra spatial dimensions not as science fiction, but as a serious, ongoing line of scientific inquiry.
In this session, Dr. K. Sridhar explores why physicists began imagining dimensions beyond length, breadth, and height, and what problems in fundamental physics these ideas were meant to address. Drawing from theoretical physics and experimental constraints, he examines how extra dimensions might be compact, elusive, and yet capable of leaving detectable traces in high-energy experiments.
The lecture follows the careful reasoning physicists use when confronting ideas that stretch intuition: how mathematical elegance motivates theory, how experimental reality disciplines it, and why many compelling ideas remain unconfirmed despite decades of effort. Along the way, it asks a central question: how far can imagination take us in physics, and where must it give way to evidence?
Rather than offering final answers, the evening invites listeners into the intellectual tension between wonder and scepticism that defines contemporary fundamental physics—and leaves us reflecting on how much of the universe may still lie beyond what we can see.

About the Speaker
K. Sridhar is a theoretical physicist and writer. He is a former professor at the Tata Institute of Fundamental Research, Mumbai, and currently teaches at Azim Premji University. His research spans theoretical high-energy physics, including brane worlds, extra dimensions, supersymmetry, quantum chromodynamics, and electroweak physics. He has worked and collaborated with institutions such as CERN, the University of London, DAMTP Cambridge, and the University of Orsay. He is also the author of both academic and literary works, including Particle Physics of Brane Worlds and Extra Dimensions, Twice Written, and Ajita.
About Pint of View
Inspired by the Lectures on Tap movement in the US, Pint of View creates informal spaces for serious ideas. It brings together philosophy, science, and art in settings where conversations unfold slowly and learning feels collective rather than instructional.
