Quantum Tunneling
    #9360262 -

From what I can understand -
its possible for a particle to travel through a solid object and has been observed on the quantum scale.

Therefore if I throw a tennis ball at wall theres a chance albeit very very slim that the ball can go through the wall.

Is this the accepted theory?

Has anyone ever thrown a ball through a wall!!?

> albeit very very slim

The 'very very slim' is so slim that it might as well be zero.  You would be more likely to win the lottery a million times in a row.

Is this because theres so many particles that the ball is made up of?

I have to admit its all way beyond my little monkey brain.  Fascinating though.

Yea, it is an accepted theory.  It describes things like radioactive decay (particles tunnel out of the nucleus) and many other things, like how computer chips behave.

The mass of the ball does play a part in how unlikely tunneling would be, more mass is less likely.  But with low mass objects it is witnessed again and again (like in decay mentioned above)

I just dug up an old calculation that shows a person running straight into a wall at 4m/s will, on average, tunnel 10^-37 meters into the wall.  Not something you want to try.  :tongue:

An apparently solid wall is actually a lot of empty space.  Maybe one day we will have technology that allows an object to go through a wall?

Fort knox would be kinda fucked if that technology was invented.

Well, empty space is a hard to to say.  If your talking from the perspective of quantum phenomenon, it may have no empty space at all!  What is 'empty space' anyway?  I dont know...  :shrug:

Heh reminds me of that guy that was obsessed with nothing.  Can't remember his name just remember my science teacher telling me about this scientist that spent all his time trying to get 'nothing' :smile:

Solid state disks (like that in ipod touch's) use quantum tunneling.

Our highest resolution microscopes use quantum tunneling.  Hence their name scanning-tunneling microscopes.

I thought Schottky barriers were an example of a practical application of quantum tunneling.
