Short-Question

# Why cant you put your hand through a solid?

## Why cant you put your hand through a solid?

You can’t put your hand through the table because the really strong electromagnetic force is causing the electrons in your hand and the table to repel! When you try to get closer, the table will move away, and this is due to the repulsion of the electrons being enough to cause a change in momentum of the table!

## Is anything really solid?

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 distances away from each other.

Why don’t we fall through the floor?

When we stand on the floor, the Pauli Exclusion Principle prevents the electrons in our feet or shoes from getting too close to electrons on the floor. This is because they are not allowed to occupy the same electron orbital. This means an electromagnetic repulsion between feet and floor is generated.

Can your finger go through the wall?

In terms of whether your hand can pass through a wall, quantum theory says that it will never actually happen. The probability is technically non-zero but it is far too small to mean anything.

### Can atoms pass through walls?

He found that, under certain conditions, atoms, electrons, and other small particles in nature can cross physical barriers that would confound macroscopic objects, moving like ghosts through walls. Since then, physicists have found that tunneling plays a key role in some of nature’s most dramatic phenomena.

### Why doesn’t gravity pull us through the floor?

When two ordinary objects, such as your shoes and the floor on which you stand, come close enough together, the electrons that surround the atoms of the floor and of your shoes repel each other strongly through the electic force (the so-called Coulomb force). But, not a force opposite to gravity.

What makes you not put your hand through a table?

This leaves one force to be the force preventing you from putting your hand through a table, electromagnetism. As you will know, everything around us is made of atoms.

Can a finger go through a solid table?

A table is always solid. yeah that was more likely just an pop-sci analogy for tunneling. maybe mindboggling but also horribly inaccurate. So by looking at that very awkward depiction of atoms it seems that there is a chance that your finger will go through the table. Maybe it will go through until it becomes blocked by other atoms.

#### Why does a table feel solid when you touch it?

It feels solid because of the dancing electrons. The table resistance is strong. Shutterstock If you touch the table, then the electrons from atoms in your fingers become close to the electrons in the table’s atoms.

#### Is it possible to pass your hand through a wall?

He’s example was his hand passing through a wall and he said that its possible except that you’d ahve to wait a few of the universes current lifespans before it would ever happen but he made it clear that there is a mathematical possibility. There is a similar hypothetical that involves nothing but classical gas kinetics.
