### Help me test and prove this theory? [closed]

My theory is called...I'm not sure yet, but it's where everything emanates pressure that pushes on everything. This is what causes gravity, so to my theory.

### Circuit elements classification

I want to understand from theoretical point of view the structure of electric circuits. I don't mean Ohm's law or the Law of induction... E.g. there are resistors $R$, capacities $C$, inductors $L$ ...

### Is it theoretically possible for a person to pass through a solid wall/object?

I understand that matter cannot pass through other solid matter because of the electrons that orbit an atom prevents this but I was curious to know if it is theoretically possible to somehow get ...

### Theoretical physics and education: Does it really matter a great deal about what happens inside a black hole, or about Hawking radiation? [closed]

I stumbled across this article http://blogs.scientificamerican.com/cross-check/2010/12/21/science-faction-is-theoretical-physics-becoming-softer-than-anthropology/ It got me thinking. Why do we ...

### 2nd order pertubation theory for harmonic oscillator

I'm having some trouble calculating the 2nd order energy shift in a problem. I am given the pertubation: $\hat{H}'=\alpha \hat{p}$, where $\alpha$ is a constant, and $\hat{p}$ is given by: ...

### Can thought experiments qualify as actual research?

I wondered whether thought experiments actually can be substituted for actual experimentation. I understand that in some cases it might be necessary, but can it be unnecessary over thinking sometimes? ...

### Can we project a 4D world using 3D video technology?

Traditional movies, TV, etc, faithfully show our 3-dimensional world using 2 dimensions. So can we have a movie that shows a 4-dimensional world using 3D technology?

### Relationship between frequency and wavelength

I am currently writing up a report for science class on the relationship between frequency and wavelength. And so i was wondering if anyone knew where i could find published results (literature value) ...

### Can a sound mathematical formula become a science theory?

Can a sound mathematical formula become a science theory if it is constructed using a pattern creation process from sense-data, applied to observations by an inductive mapping, in contrast to ...

### Dense Spherical Black Hole Shell with a Region Inside

I'm going to propose a thought experiment, based on two ideas. One: A uniform spherical shell, by the Shell Theorem, does not exert any gravitational force on objects existing in the interior of the ...

### Does the mathematics of physics require impure set theory?

Suppose for the sake of this question that all mathematics is ultimately reducible to set theory in such a way that the only mathematical objects there really are, are sets. Now, there is a common ...
