| - | Supergravity is a proposed theory of [[speculative_theories:quantum_gravity|quantum gravity]], i.e. a theory that unifies [[theories:classical_theories:general_relativity|general relativity]] with [[theories:quantum_theory|quantum theory]]. | + | |
| - | <tabbox Layman> | + | The basic idea of supergravity is that [[theories:speculative_theories:supersymmetry|supersymmetry]] is a [[advanced_tools:gauge_symmetry|gauge symmetry]]. |
| - | <note tip> | + | When we combine these two ideas we end up automatically with a particle that looks like the particle that we expect to mediate gravity - the graviton. |
| - | Explanations in this section should contain no formulas, but instead colloquial things like you would hear them during a coffee break or at a cocktail party. | + | |

In the process of doing this at least one spin $2$ particle emerges, which is then interpreted as the gravitation that mediates gravity. </note> | + | The basic idea of supergravity is to [[advanced_tools:gauge_symmetry|gauge]] supersymmertry.

| It is hard to find an obituary for supergravity in any scientific journal. Many physicist-hours were spent on supergravity, efforts either to prove by direct mathematical demonstration that it was free of infinities at all levels, or to find examples of infinities that did not disappear quietly. The latter was the eventual outcome. No doubt some physicists paused briefly to reflect on the passing of what had seemed a wonderful idea, but no one took the time to eulogize. Scientists are not inclined to pause and reflect at the demise of a once-bright idea; if they experience any grief, they find release from it in action, not in mourning. Their Idea of recovery is to move as quickly as possible to the next bright idea. And, as it happens, a new idea—another super idea—was waiting for them. | It is hard to find an obituary for supergravity in any scientific journal.
