Let me summarize my thoughts about topics in theoretical physics:
- Theory of everything: The theory of everything aims to unite all the four forces of nature into one single elegant equation.
- Supersymmetry: important as, roughly put, it explains the nature of force in terms of matter.
- The gravitino is the supersymmetric partner of graviton, which is a hypothetical particle that mediates the gravitational force.
- Dark matter candidate: It is theorized that the graviton has no mass and on the other hand gravitino is very massive. Hence some nerds proposed dark matter may be made mainly of gravitinos.
- Existence of gravitinos: It is suspected that early in the formation of Universe when it was still mostly in a plasma state, gluons (the force carrier of strong nuclear force) collided with each other and produced gravitinos.
My questions are:
- Is there any reliable, direct or indirect, method to detect gravitinos?
- If gravitinos were observed, would it mean that supersymmetry was the theory of everything?
