Connor Raven asked the Naked Scientists:
   
A quick question that i heard while watching QI that i thought would be interesting to put on the forum to see people's responses and views.

"What would happen if an immovable object collided with an unstoppable force?"

What do you think?

According to Relativity, no object anywhere in the cosmos can be considered to be motionless. Motion is relative to the observer and because every observer is also in motion, nothing can be seen as motionless. Therefore; because everything is in motion, nothing is immovable.

An immovable object would require infinite mass. An unstoppable force would require infinite energy. They cannot coexist, by definition of "infinite".

The existence of one precludes the existence of the other therefore they can not meet.
The question has no meaning.

When an irresistible force such as you
Meets an old immovable object like me
You can bet just as sure as you live

Something's gotta give
Something's gotta give
Something's gotta give

I agree, absolutely, but would be fascinated to know your reason for saying this.

E = mc^2. In order to generate infinite energy (the property of an unstoppable force) , you must convert infinite mass, which means that however hard you look, you can't find any more mass (and if you did, you'd have to convert it to energy) therefore there can be no immovable object.

The closest you could come would be if the universe instantaneously collapsed into its own immoveable object (the singularity) and the gravity of the singularity had to combat the momentum of the collapsing universe. The result would be the big bang. Presumably this would happen when time stopped and space disappeared.
