Anhilliation

From Scott’s profile:

What would happen if an irresistable force (i.e. a cannonball that connot be stopped by anything) met an immovable object (i.e. a wall that cannot be moved by anything)?

This sparked an interesting conversation:

Minh Nguyễn

What would happen? Instant anhilliation. Case in point: when hydrogen and antihydrogen collide, they anhilliate each other, leaving only photons (light) and pions (the lightest type of meson) in their wake.

Scott Feister

Ah, I think you overlooked a key paradox.

Nothing would happen because the situation is impossible.

Minh

But antimatter is a paradox.

Scott

The terms irresistable force and immovable object cannot coexist.

Minh

Antimatter is, in a sense, existing matter, yet, in another sense, is the absence of matter — in fact, its exact opposite.

Scott

Dark matter.

Minh

Not necessarily, although that is one explanation.

You could also view antimatter as matter, just with a negative mass. But that brings us back to the beginning.

Don’t you just love physics? Or, should I say, antiphysics?

Scott

Actually I’m thinking of going into something science.

…

Given, I’m not the expert on antimatter. But I do think that it would be the solution to the paradox.
