The universe burst into existence some 13,799,000,000 years ago. Why did it become this universe? Why does it have quarks and electrons; and elements including carbon, hydrogen, nitrogen and oxygen; and gravity to grow galaxies; and planets orbiting vast numbers of stars; and all of the ingredients that lead to life? Doing this required many […]

Taking Lessons from the Universe
Arithmetic is fundamental to science; but we tend to take it for granted. Few realize its foundations are shaky. Now there are exciting ways to firm them up. We are sold a knowledge pyramid like this: Sciences rest on a foundation of physics; physics on math; math on arithmetic. And arithmetic on logic— but, actually, […]
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 […]
A Foundation for Building Real Physics (At Last)
Physics has two great theories, general relativity and quantum mechanics. Each does very well in its domain. That is nice but plainly isn’t real. Each is fundamentally at odds with the other. And neither of them works at all with the conditions that existed when the universe began. How can we find a single theory […]
