Hawking and the End of Physics

Is physics ending? Serious people say so, not always seriously. Are they right and should we care? In 1996 American science writer John Horgan wrote a book, The End of Science. His thesis was that all the big stuff has been done already, that what he calls ‘the primordial human quest to understand the universe […]

Maybe the answer is: A grasp of quantum space and the topology of twist. It’s a massive problem in more […]

How Can a Universe Begin?

Of all questions the most fundamental is: What was the initial condition of the universe? It is fundamental for philosophy and religion. It is even more fundamental for physics. Unfortunately it is a realm where physics fears to tread. Yet we may need to tread this realm to find the much-sought Theory of Everything or […]

Hawking’s Missing Black-Hole Radiation

There are billions of black holes in our universe. Maybe gazillions. Stephen Hawking says they give off a strange kind of radiation. So we should see them, right? Here’s a cosmological Catch-22. To set the scene, the Albert Einstein Institute says: ‘If, in our universe’s fiery youth, “mini black holes” of very little mass had […]

Both of these exemplars hold the degree of Doctor of Philosophy so they should know. But so do I and I […]
