Protons and Electrons Occupying the Same Space
When it comes to atoms electrons can't fall into the nucleus, which besides the off hand uncertainty explanation, I'm not sure which force prevents them from falling into the nucleus. I thought I ...

If atoms are mostly empty space, why doesn't light pass through everything?
Atoms are mostly empty space, and although I now understand why matter doesn't pass through other matter, why don't photons pass through the empty space of the atoms? Is it the same sort of idea as ...

On the collision of two electrons in a particle accelerator
The coulombic force between two charges is
$$
F = \frac{k q_{1} q_{2}}{r^{2}}
$$
For two negative charges this will be repulsive. From the equation, as $r$ tends to zero the force approaches infinity....

In truth, only atoms and the void
I have a question about this motto used by Sean Carroll in his blog:
In truth, only atoms and the void.
Can you explain what this sentence means? My interpretation is that the sentence does not ...

Is it possible to use force to reduce the empty space in an atom?
Atoms are mostly empty space (at least from what I've heard) so is it technically possible to shrink the space between the electrons and the nucleus of an atom?

Where does the energy within atoms come from?
Most kinds of energy I know about involve a finite measurement and are transferred. In other words, energy in the universe is finite and is not lost or gained but only transferred through space one ...

How much space does an atom occupy? [closed]
So my stupid question is: we know that in the classical model of a atom there is a nucleus at the middle and electron revolving around it in orbits numbered from 0 to infinity. So according to this an ...

How can 0-dimensional particles or 1-dimensional strings be 3D matter? [closed]
According to the latest information we got
String theory is a theoretical framework in which the point-like
particles of particle physics are replaced by one-dimensional objects
called strings....

How does weight add up to press on things?
I think I understand how pressure works with gases. More molecules bouncing around -> more random impacts -> stronger force.
But I realized to my embarrassment that I don't understand how solid ...

How does the Earth bring down a falling object's velocity to zero on contact?
How does the earth bring down a falling object's velocity to zero on contact?
If the normal force on an object from a horizontal surface is equal to the weight of the object, the object could never ...

Two stones (bosons) in one place
A macroscopic object (let's call it "stone") may incidentally be a boson, right?
But identical bosons are "allowed" to have the same quantum state.
From this I conclude that two identical stones may ...

What would the properties of a truly solid object be? [closed]
As most people who have done any amount of physics know, no object is truly solid; go small enough and you will find vast amounts of space containing atoms, electrons, etc, all relatively enormous ...

Do virtual particles pop in and out of existence in the space just outside the nucleus? [duplicate]
This question is similar to one asked if virtual electrons exist outside the nucleus, but please note, my question says virtual particles. It is not a duplicate. I read so often that matter is mostly ...

Why are atoms not destroyed when dropped?
I made the following thought experiment: Dropping a gold ring on a wooden table.
It drops, hits the table, bounces off, hits again with less velocity and so on until it finally rests.
Now consider an ...
