In 60 Seconds You Will Realize that Time is Real
Everything we experience and know about is caught in time, is caught in a moment, is not an illusion.
Lee attended Harvard University for graduate school receiving a Ph.D. in theoretical physics in 1979. He held postdoctoral positions at the Institute for Advanced Study in Princeton, The Institute for Theoretical Physics (now KITP) in Santa Barbara and the Enrico Fermi Institute at the University of Chicago. This was followed by faculty positions at Yale, Syracuse and Penn State Universities, where he helped to found the Center for Gravitational Physics and Geometry. In September of 2001 he moved to Canada to be a founding member of the Perimeter Institute for Theoretical Physics, where he has been ever since.
Lee's main contributions to research are so far to the field of quantum gravity. He was, with Abhay Ashtekar and Carlo Rovelli, a founder of the approach known as loop quantum gravity, but he has contributed to other approaches including string theory and causal dynamical triangulations. He is also known for proposing the notion of the landscape of theories, based on his application of Darwinian methods to Cosmology. He has contributed also to the foundations of quantum mechanics, elementary particle physics and theoretical biology. He also has a strong interest in philosophy and his three books, Life of the Cosmos, Three Roads to Quantum Gravity and The Trouble with Physics are in part philosophical explorations of issues raised by contemporary physics.
By "time is real" I mean to say that everything we experience and know about is caught in time, is caught in a moment, is not an illusion. It’s the deepest clue we have, perhaps, to the nature of reality.
This is to counterpose the picture which was developed in physics from Galileo and Newton and Descartes down to the present quantum cosmologists: that time is an illusion, time is an auxiliary; that reality is behind this veil of illusion, is timeless, is permanent, is outside of time. As Einstein and many other people have said, our experience of the distinction between past, present and future is an illusion and reality is just the whole history of the world at once.

Are university safe spaces killing intellectual growth?
Our experience of time may be blinding us to its true nature, say scientists.
- Time may not be passing at all, says the Block Universe Theory.
- Time travel may be possible.
- Your perception of time is likely relative to you and limited.
From questionable shipwrecks to outright attacks, they clearly don't want to be bothered.
- Many have tried to contact the Sentinelese, to write about them, or otherwise.
- But the inhabitants of the 23 square mile island in the Bay of Bengal don't want anything to do with the outside world.
- Their numbers are unknown, but either 40 or 500 remain.
