21193 | The universe is 68% dark energy, 27% dark matter, 5% regular matter [Hesketh] |
Full Idea: The most precise surveys of the stars and galaxies tell us that the universe is made up of 68% dark energy, 27% dark matter, and just 5% regular matter (the stuff of the Standard Model of particle physics). | |
From: Gavin Hesketh (The Particle Zoo [2016], 09) | |
A reaction: Regular matter - that's me, that is. |
21198 | If a cosmic theory relies a great deal on fine-tuning basic values, it is probably wrong [Hesketh] |
Full Idea: If a theory has to rely on excessive 'fine-tuning', a series of extremely unlikely events in order to produce the universe we see around us, then it is extremely unlikely that this theory is correct. | |
From: Gavin Hesketh (The Particle Zoo [2016], 10) | |
A reaction: He says the Standard Model has 26 parameters which are only known by experiment, rather than by theory. So instead of saying '...so there is a God', we should say '...so our theory isn't very good'. |
