Paul Davies PHD - THE IMPLICATIONS OF EINSTEIN

What are the implications of Einstein’s predictions? Has our understanding of reality integrated the implications of this thinking? His General and Special theories of relativity have completely changed the way we see gravity, energy, mass, space and time, even size - but how? Physicists may find it easy to understand what his ideas mean; like this quote “The distinction between the past, the present and the future is nothing but a stubbornly persistent illusion”. But for us, the general public, just thinking that the the arrow of time is an illusion, is enough to give us a bad headache and leave us wishing that Newton was right after all. But that’s not what we do on Chasing Consciousness, our mission is the same as always, to update our world view to match new theories. Now this sounds like no small feat, but have no fear, all will be be clarified by a man with a skill for presenting complex ideas in a way we can all understand, one of the worlds most published popular science writers, Professor Paul Davies.

Paul Davies is a Cosmologist and Professor of Physics and Director of the Beyond Center for Fundamental Concepts in Science at Arizona State University. His work has covered topics as far reaching as Cosmology, Quantum Fields and Astrobiology, with a sprinkling of the Search for Extra terrestrial Intelligence (SETI) and cancer research to boot. He’s the bestselling author of almost thirty popular science books, his many awards include the Templeton Prize and the Faraday Prize of the Royal Society. He is a Member of the Order of Australia and even has an asteroid named after him! Quite a career!

His new book ‘What’s eating the universe’, that covers many of the topics we’ll touch on today, is out now.
