Can I put the universe in a drop?

From the point of view of mathematics, there seems to be no obstacle for a noncompact manifold to be embedded in a closed manifold (for example, the winding of a torus everywhere densely...

What are the interpretations of Planck length?

For example, can it be interpreted as Lorentzian reduction of the length of the Planck interval action caused by the acceleration given by the gravitational constant? Of course, in this case...

They can make friends theory of general relativity and the ether?

Attempts to describe general relativity by a continuum in Minkowski space were made but were unsuccessful. Please see how it turned out in my article "Applications of the Local Algebras of Vector...

Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

Why almost every element would be metallized in sufficiently high pressure and low temperature?

(This statement is from wikipedia, BTW). What is so special about metallic bond that is limiting high-P low-T state of a matter (as long as individual atoms exist, not white dwarf of neutron star...

Should we reduce the standard unit of length to 0.31951540592 meter ?

The reasoning behind this question is to align the ratios of the proton potential in energy per charge to the speed of light in distance per time. As these two dimensions appear to be related,...

Is is possible to pole with corona poling pellets of the sample material instead of thin films?

As it is highly probable that pellets will have a higher degree of air gaps and voids than thin films, is it possible to pole the samples with corona poling nevertheless? Or is there the...
