Loop quantum gravity clearly offers more testable predictions than string theory.

I'm listening. Amuse me.

Okay, well for one thing, we expect quantized space-time to manifest itself

as minute differences in the speed of light for different colors.

Balderdash. Matter clearly consists of tiny strings.

Are you gonna let him talk to me like that?

Okay, well, there is a lot of merit to both theories.

No, there isn't. Only loop quantum gravity calculates the entropy of black holes.

Sheldon, don't make that noise. It's disrespectful.

I should hope so. It's a snort of derision.

You agree with me, right? Loop quantum gravity is the future of physics.

Sorry, Leslie, I guess I prefer my space stringy, not loopy.

I'm glad I found out the truth about you before this went any further.

Truth? What truth? We're talking about untested hypothesis. It's no big deal.

Oh it isn't? Really?

Tell me Leonard, how will we raise the children?

I...

I guess we wait until they're old enough and let them choose their own theory.

We can't let them choose. Leonard, they're children!

Wait, where are you going?

I'm sorry.

I could have accepted our kids being genetically unable to eat ice cream

or ever get a good view of a parade.

But this?

This is a deal breaker.
