Theory of everything trivia questions
A "theory of everything" would aim to unify quantum physics with what other major theory?
Answer: General relativity
Bonus fact: The goal is a single framework capable of describing all fundamental forces and particles.
Which force remains outside the Standard Model and is therefore a major obstacle to a theory of everything?
Answer: Gravity
Bonus fact: General relativity describes gravity extremely well on large scales, while quantum theory governs microscopic physics.
Which two research programs are among the best-known attempts to move toward a theory of everything?
Answer: String theory and loop quantum gravity
Bonus fact: The two approaches differ sharply in how they attempt to quantize spacetime and gravity.
A grand unified theory tries to combine which fundamental forces?
Answer: Strong, weak, and electromagnetic forces
Bonus fact: A GUT does not usually include gravity, so it falls short of a full theory of everything.
