    • ‘We have to two theories that are both extremely successful but mutually incompatible - Einstein's general relativity and the standard model of particle physics.’
    • ‘We know the standard model of particle physics is not the final word, and quantum theory has yet to be married to gravity - neither is complete without the other.’
    • ‘Indeed, at the time this is written, there is only one clear-cut piece of experimental evidence that the standard model is not an exactly correct theory.’
    • ‘The most familiar, and second strongest, force described in the standard model is electromagnetism.’
    • ‘String theory is ‘large enough’ to include the standard model and includes gravity as a must.’
