Is string theory right? Is it just fantasy? Caught in the landscape Out of touch with reality Compactified On S5 or T*S3 Space is a pure void Why should it be stringy? Because it’s quantum not classical Nonrenormalizable Any way you quantize You’ll encounter infinity You see Quanta Must interact Via paths we understand Using Feynman diagrams Often they will just rebound But now and then they go another way A quantum Loop Infinities will make you cry Unless you can renormalize your model Of baryons fermions And all other states of matter Curved space The graviton Can be thought of as a field But these infinities are real In a many-body Loop diagram Our results diverge no matter what we do A Quantum Soup any way you quantize Kiss your fields goodbye Guess Einstein’s theory wasn’t complete at all! I see extended 1D objects with no mass What’s their use? What’s their use? Can they give us quark plasma? What to minimize? What functional describes this String? Nambu-Goto How to quantize I don’t know Polyakov!
