Thread: Fluid Dynamics of Sub-Planck Lengthed Particles

I was provided with a link to Einsteins View on the compatibility of an aether with relativity on another site. It has made me think a bit further on the nature of the proposed aether. Einstein says that for the aether to be consistent with Relativity it can not be thought of as existing of individual particles in relation to which motion can be measured. But then how can it have the needed properties for electromagnetic radiation and gravity to exist? Logic dictates that everything is infinitely devisable, for when you choose to stop dividing after any number of divisions you could still in principle divide to yet another level. So if you take it to the limit (pun intended) mathematically, you will be left with a particle with dimensions that tend toward zero.

The seperation between these particles would also tend towards zero, but slight variations in these seperations would allow for any kind of 3D dynamics on the makro scale.

The question is: How would the fluid dynamics of these particles (strings maybe ) be affected when the particles and seperations are on a sub Planck length scale?

The simplest answer is that there is no aether. There never was. That is the viewpoint of mainstream physics and it is good enough for me.

But that position need not stop physicists from playfully conjecturing "something" additional in our store of accepted knowledge. After all, we still have no satisfactory answer to action at a distance. Or do we? Exchange of particles? Disturbance in the Force?

So let us assume an aether and give it properties. Run with the equations and so how far they will take us. Who knows -- maybe there will be a breakthrough? A new experiment with remarkable results? Not necessarily about aether, but then again, why not? Go for it, guys!

Such matters are not my specialty. I am quite content to embrace the mainstream notion: No Aether. To every soul who is more imaginative than I, I wish you good luck.

Ok. A subset of this idea is being discussed in the mathematics section and on some other forums. Also, this is linked to my Fractal Thread on this site and another one. I'll put some of it here, if that is ok...

Me:
"I was reading through the wiki article on Superfluidity and came across this gob-smacking passage:

"A more fundamental property than the disappearance of viscosity becomes visible if superfluid is placed in a rotating container. Instead of rotating uniformly with the container, the rotating state consists of quantized vortices. That is, when the container is rotated at speed below the first critical velocity (related to the quantum numbers for the element in question) the liquid remains perfectly stationary. Once the first critical velocity is reached, the superfluid will very quickly begin spinning at the critical speed. The speed is quantized - i.e. it can only spin at certain speeds."

This is exactly the type of stuff I was thinking and wondering about! Could the medium I am considering produce such vortices? Can vortices have a fractal nature, even if only stochastically? Could an oscillating source create the kind of vortices I am looking for?"

Every theory I hear these days sounds more and more like my own.

In my best answer to your question KALSTER, there is Planck time, mass and length. They all seem on a small scale to work fine, but all sub, I don't know if any effects would take place at all, at least not the dimensions we can concieve.

I'll admit that I didn't read the articles and only glanced a bit at what you linked but if I logically think, the smaller things get, to large things, the reactions may seem tiny, but to things of the same size they may seem equally large, and those all put together may create something as we being large, see as large. Don't know if this helps, I hope it does.
