Twin mysteries: A ghostly fundamental particle and a physicist who disappeared after saying its antiparticle may not exist

Twin mysteries arose around 1937 when Italian theoretical physicist Ettore Majorana suggested neutrinos are their own antiparticles. Soon afterward he took the night ferry from Palermo to Napoli and vanished, leaving us to ask: What happened to him; and was he right? The Standard Model has a place for every known elementary particle. It says […]

Physics has long been confused about the concept of ‘now’. New insights show that it is fundamental.

A sense of Now is the universal human experience. Yet modern physics cannot handle the concept of the present moment. Indeed relativity—our great theory of space and time—insisted on embedding it within a time dimension and then crossbreeding this dimension with three space dimensions to make spacetime. This was a blunder. It blocks progress. Physics […]

Could the Universe Have Only Two Dimensions?

It’s strange but true: Physics is now studying the universe as if it is a two-dimensional hologram. How did this come to be? And what does it mean? The 3D/2D duality is known as the holographic principle. Two decades ago American theoretical physicist Leonard Susskind described it this way: ‘In a certain sense the world […]

The Beginning of Time

When did time begin? Science now has an answer. How did time begin? For millennia this was a subject for speculation, little of it based on science. But there is now a philosophic answer. Space came first. Time began soon after space. Very soon. Here’s how. From recent measurements we know that time began 13,799,000,000 […]

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 […]
