The fundamental constants of nature—such as the speed of light, Planck’s constant, and Newton’s gravitational constant—are thought to be constant in time, as their name suggests. But scientists have questioned this assumption as far back as 1937, when Paul Dirac hypothesized that Newton’s gravitational constant might decrease over time.

Now in a new paper published in Physical Review Letters, Yevgeny V. Stadnik and Victor V. Flambaum at the University of New South Wales in Sydney, Australia, have theoretically shown that dark matter can cause the fundamental constants of nature to slowly evolve as well as oscillate due to oscillations in the dark matter field. This idea requires that the weakly interacting dark matter particles be able to interact a small amount with standard model particles, which the scientists show is possible.

In their paper, the scientists considered a model in which dark matter is made of weakly interacting, low-mass particles. In the early Universe, according to the model, large numbers of such dark matter particles formed an oscillating field. Because these particles interact so weakly with standard model particles, they could have survived for billions of years and still exist today, forming what we know as dark matter.

Although these low-mass dark matter particles are weakly interacting, they are thought to still interact with standard model particles to some extent, but it’s unclear exactly how much. By using data from experiments that have measured the amount of helium produced during big bang nucleosynthesis, as well as measurements of the rare element dysprosium and the cosmic microwave background, Stadnik and Flambaum have derived the most stringent limits to date on how strongly such dark matter particles interact with photons, electrons, and light quarks, improving on existing constraints by up to 15 orders of magnitude.

The new limits on the dark matter interaction strength allow for the possibility that an oscillating, low-mass dark matter field coupled to standard model particles causes variations in the fundamental constants. As the scientists explain, this could have important implications for understanding life’s origins.

“The fundamental constants are ‘fine-tuned’ to be consistent with the existence of life in the Universe,” Stadnik told Phys.org. “If the physical constants were even slightly different, life could not have appeared. The discovery of varying fundamental ‘constants’ may help shed important light on how the physical constants came to have their life-sustaining values today. We simply appeared in an area of the Universe where they are consistent with our existence.”

Pretty interesting. If this is correct the universe “tunes” itself (and life) over “time” and those “settings” might be different in a different part of the universe. So in a sense different parts are evolving to be different from each other, and the “life” that exists there could be very different to the life that exists in this part.

Theory of Everything; Physical, Quantum and Life as the bridge

There is currently a problem in Physics; How to combine Classical Physics with Quantum Physics, into a Grand Unified Theory of Everything.

In my opinion, Hawkings, being the brightest physicist, thinks that there will not be a Theory of Everything.

Stephen Hawking says there’s no theory of everything

How do you square deterministic Classical Physics with the probabilistic Quantum Physics?

I think, the reason physicists cannot find the theory is because they ignore one thing in the universe as part of physics. Life.

This was not always so, Erwin Schrödinger wrote a book “What is Life?” that touched on DNA among other ideas. This became a taboo, but thankfully it is starting to come up again.

Life is the bridge between Classical and Quantum Physics. Will be interesting to see if this conjecture is correct.

bool localCausality = false

Quantum process demonstrates superposition of ordered events

Thought this was interesting. Both local causality and realism seem to be false from our current understanding.
