Was Einstein right about probability being inadequate?

Nov 09, 2013 Posted Under: cosmology, philosophy, physics

My son has been suggesting for some time now that I contact actual scientists about my search for physics which better explain our universe.  Finally I have found one edge of a larger community of such maverick thinkers in the annual contests of Max Tegmark’s Foundational Questions Institute. The first contest essay I read last […]

Angular Momentum Question

Sep 28, 2012 Posted Under: physics

It seems to me all momentum is angular momentum.  An ice skater pulling in her arms will rotate faster, and conversely, extending her arms will slow her rotation.  If her arms are extended to the radius of the planet, her rate of spin will slow to unnoticeable (to us), seeming instead to go in a […]

Grokking Gravity

Sep 17, 2012 Posted Under: cosmology, physics

After remembering my dreams in the bath the other morning, I puzzled some more about gravity, wondering “where is the equal and opposite reaction to the force of gravity?” Looking at gravity from Einstein’s point of view, that it is a curving of spacetime, allowed me to wonder if there shouldn’t be a corresponding negative […]

Entanglement and Agreement and What’s Underneath?

Apr 09, 2012 Posted Under: physics

While reading the Quantum Reality article in last week’s ScienceNews, I was inspired to dig a little deeper and found this review of work by G. Chiribella, G. D’Ariano, and P. Perinotti last year. It points up a fundamental flaw in my previous attempts to understand quantum mechanics — that there are “events” and “observers”. […]

Mass as the Curvature of Space-Time

Jul 25, 2011 Posted Under: physics

After noticing in my previous post that the highest energy photon would be the smallest black hole, I continued wondering about the smallest possible mass. And after dancing around the obvious non-starter of a no energy photon, because zero energy would be equivalent to infinite wavelength, it occurred that it could be descriptive of the […]

In Search of the Least Mass …

May 11, 2011 Posted Under: physics

I got to wondering a couple of weeks ago, what is mass? What is the smallest possible amount of mass that theoretically could exist? It is thought the least massive particles we are aware of are the lightest of the 3 “flavors” of neutrino, in the range of 1/2 to 1 electron-volt. Then in the […]

Whence the redshift?

Apr 06, 2011 Posted Under: physics

A few weeks back my son asked me to explain the redshift, and I discovered I could not! Having started with the usual comparison to the Doppler effect in the sound waves of a train or siren, it suddenly occurred to me there was no correspondent to the collection of air molecules the sound wave […]
