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 […]

Planck-scale: The Answer to Figuring Out Our Weird Universe New fundamentals needed now.
The messages are clear but are we listening? For almost a hundred years we’ve known the universe has been expanding since it began. For almost twenty years we’ve known the expansion has been accelerating for billions of years. With each new discovery physics hastens to adjust its theories to fit the new facts. Now more […]
What Made the Big Bang Big? What Made the Big Bang Bang? A radical rethinking of our understanding of the universe
Two weeks ago we took a look at a question from systems engineer Muralidharan Thiyagarajan. Referring to the observation that space everywhere is expanding, he asks: ‘What creates the space?’ My answer is: At the Planck level (named for German physicist Max Planck who first described it) where space is made of incredibly tiny quanta, […]
Making Space
Precise measurements say the universe is expanding. The measurements don’t show new matter. They show new space. This leaves those who think of space as empty with a conceptual puzzle. As cosmologist Marcus Chown once said, ‘How can nothing expand?’ Muralidharan Thiyagarajan, who is a systems engineer with Infosys in Chennai, has another way to […]
The Next Scientific Revolution
Breaking news: We are seeing a new Scientific Revolution. It will be the biggest ever. And I mean ever. Odds on it will be called “the Planck revolution”. Does German physicist Max Planck deserve this? I don’t think so. I think of it as the Riemann revolution. Readers know that more than 150 years ago […]
The Shifting Shape
Reader Stevo asks a deep question: ‘If space is granular and Planck size is the shortest “length” then what geometric “shape” is a single Planck “thingie”?’ Geometry studies size and shape. Last week we saw Bernhard Riemann in 1856 divining how to do geometry in either of two different kinds of space: continuous space and […]
Three Roads to Multiverses
Last week we took a wide-lens look at the multiverse phenomenon that’s sweeping through the global physics village. Let’s look closer. South African cosmologist George Ellis says (about the simplest multiverses): The proponents are telling us we can state in broad terms what happens 1,000 times as far as our cosmic horizon, 10100 times, 101,000,000 […]
Buddha, Physics and the End of Zen
A history by writer Thomas Hoover tells us that the words and actions of Zen masters through the ages all strive to an end: That end is an intuitive realization of a single great insight―that we and the world are one. … Our rational intellect merely obscures this truth, and consequently we must shut it […]
In the Universal Conversation: Physics and Religion ― Deep Divide or Meeting Place?
Back to the writing of Time One. The book’s narrator is mentoring a hack detective who’s supposed to figure how the universe began like it’s a crime scene. The detective knows from nothing. He says his name is Frank. (The narrator disbelieves him.) The narrator is a beach-bum with a philosophic education. His job is […]
