What's the Nature and Rules of this Playground we're Playing In?

Let's Ask Ski !

Spacetime -- a creation of well-known actors?
The Henryk Niewodniczanski Institute of Nuclear Physics Polish Academy of Sciences, November 8. 2018.

MAIN POINTS

"What is spacetime? The absolute, unchanging, ever- and omni-present arena of events? Or perhaps it is a dynamic creation, emerging in some way on a certain scale of distance, time or energy?"

"Are space and time separated from matter, creating a “container” for motions and events occurring with the participation of particles, as Democrit proposed in the 5th century BC? Or perhaps they are attributes of matter and could not exist without it, as Aristotle suggested a century later?"

"In quantum mechanics, events take place in a rigid arena with uniformly flowing time. Meanwhile, in the general theory of relativity, matter deforms elastic spacetime (stretching and twisting it), and spacetime tells particles how to move."

"In 1899, German physicist Max Planck noticed that with certain combinations of some constants of nature, very fundamental units of measurement could be obtained. Only three constants – the speed of light c, the gravitational constant G and Planck's constant h – were sufficient to create units of distance, time and mass, equal (respectively) to 1.62 · 10-35 m, 5.39 · 10-44 s and 2.18 · 10-5 g. According to today’s mainstream belief, spacetime would be created at Planck’s length. In fact, there are no substantive arguments for the rationality of this hypothesis."

Ski's Answer

"Professor Piotr Zenczykowski from the Institute of Nuclear Physics of the Polish Academy of Sciences (IFJ PAN) in Cracow systematizes the observations of various authors on the formation of spacetime, and argues that the hypothesis about its formation at the scale of quarks and hadrons (or quark aggregates) is quite sensible for a number of reasons."

What is Matter?

For Example
"At present, we first seek to construct a quantized, discrete spacetime, and then ‘populate’ it with discrete matter. However, if spacetime was a product of quarks and hadrons, the dependence would be reversed: the discrete character of matter should then enforce the discreteness of spacetime!"” says Prof. Zenczykowski, and adds: “"Planck was guided by mathematics. He wanted to create units from the fewest constants possible. But mathematics is one thing, and the relationship with the real world is another. For example, the value of Planck's mass seems suspicious. One would expect it to have a value rather more characteristic for the world of quanta. In the meantime, it corresponds to approximately 1/10 of the mass of a flea, which is most certainly a classical object."

Are We the Products of a Six Dimensional Space-Time Thingy?
"Another factor in favour of the formation of spacetime at the scale of quarks and hadrons are the properties of the elementary particles themselves. For example, the Standard Model does not explain why there are three generations of particles, where their masses come from, or why there are so-called internal quantum numbers, which include isospin, hypercharge and colour. In the picture presented by Prof. Zenczykowski these values can be linked to a certain six-dimensional space created by the positions of particles and their momenta. The space thus constructed assigns the same importance to the positions of particles (matter) and their movements (processes). It turns out that the properties of masses or internal quantum numbers can then be a consequence of the algebraic properties of 6D space. What's more, these properties would also explain the inability to observe free quarks."

Ski Concludes,
"However, it is not very clear what to do next with this picture. Each subsequent step would require going beyond what we know. And we do not even know the rules of the game that Nature is playing with us, we still have to guess them! However, it seems very reasonable that all constructions begin with matter, because it is something physical and experimentally available. In this approach, spacetime would only be our idealization of relations among elements of matter"”, sums up Prof. Zenczykowski.

 

The Bottom Line

It is very important to know if the chicken or the egg came first.

Support Tahoe to Whitney

The Tahoe to Whitney Trail Guide and Magazine are walked, written, funded, and supported by my efforts, with the help of kindred spirits and my sister.

We offer valuable Trail Guide, Skills, Weather, News and Analysis.

My goal is to get you out to see your natural and social potential. Help me keep this unique resource accessible and expanding towards its potential. We've a lot of miles to cover ahead...

I NEED HELP!
If you feel these efforts are valuable, I'm cordially inviting you to support them, here:

 

 

I am currently working towards publishing the completed guide between Tahoe & Yosemite as an e-book, while converting this "blog" to a fine magazine format. You will like the results! Help Tahoe to Whitney reach its potential!
