Fine Tuning Parameters for the Universe
- ratio of number of protons to number of electrons
if larger: electromagnetism would dominate gravity, preventing galaxy, star, and planet formation
if smaller: same as above- expansion rate of the universe
if larger: no galaxies would form
if smaller: universe would collapse, even before stars formed- entropy level of the universe
if larger: stars would not form within proto-galaxies
if smaller: no proto-galaxies would form- mass density of the universe
if larger: overabundance of deuterium from big bang would cause stars to burn rapidly, too rapidly for life to form
if smaller: insufficient helium from big bang would result in a shortage of heavy elements- velocity of light
if faster: stars would be too luminous for life support if slower: stars would be insufficiently luminous for life support- age of the universe
if older: no solar-type stars in a stable burning phase would exist in the right (for life) part of the galaxy
if younger: solar-type stars in a stable burning phase would not yet have formed- initial uniformity of radiation
if more uniform: stars, star clusters, and galaxies would not have formed
if less uniform: universe by now would be mostly black holes and empty space- average distance between galaxies
if larger: star formation late enough in the history of the universe would be hampered by lack of material
if smaller: gravitational tug-of-wars would destabilize the sun's orbit- density of galaxy cluster
if denser: galaxy collisions and mergers would disrupt the sun's orbit
if less dense: star formation late enough in the history of the universe would be hampered by lack of material- average distance between stars
if larger: heavy element density would be too sparse for rocky planets to form
if smaller: planetary orbits would be too unstable for life- fine structure constant (describing the fine-structure splitting of spectral lines) if larger: all stars would be at least 30% less massive than the sun
if larger than 0.06: matter would be unstable in large magnetic fields
if smaller: all stars would be at least 80% more massive than the sun- 12C to 16O nuclear energy level ratio
if larger: universe would contain insufficient oxygen for life
if smaller: universe would contain insufficient carbon for life- decay rate of 8Be
if slower: heavy element fusion would generate catastrophic explosions in all the stars
if faster: no element heavier than beryllium would form; thus, no life chemistry- initial excess of nucleons over anti-nucleons
if greater: radiation would prohibit planet formation
if lesser: matter would be insufficient for galaxy or star formation- polarity of the water molecule
if greater: heat of fusion and vaporization would be too high for life
if smaller: heat of fusion and vaporization would be too low for life; liquid water would not work as a solvent for life chemistry; ice would not float, and a runaway freeze-up would result- supernovae eruptions
if too close, too frequent, or too late: radiation would exterminate life on the planet
if too distant, too infrequent, or too soon: heavy elements would be too sparse for rocky planets to form- white dwarf binaries
if too few: insufficient fluorine would exist for life chemistry
if too many: planetary orbits would be too unstable for life
if formed too soon: insufficient fluorine production
if formed too late: fluorine would arrive too late for life chemistry- ratio of exotic matter mass to ordinary matter mass
if larger: universe would collapse before solar-type stars could form
if smaller: no galaxies would form- number of effective dimensions in the early universe
if larger: quantum mechanics, gravity, and relativity could not coexist; thus, life would be impossible
if smaller: same result- number of effective dimensions in the present universe
if smaller: electron, planet, and star orbits would become unstable
if larger: same result- mass of the neutrino
if smaller: galaxy clusters, galaxies, and stars would not form
if larger: galaxy clusters and galaxies would be too dense- big bang ripples
if smaller: galaxies would not form; universe would expand too rapidly
if larger: galaxies/galaxy clusters would be too dense for life; black holes would dominate; universe would collapse before life-site could form- size of the relativistic dilation factor
if smaller: certain life-essential chemical reactions will not function properly
if larger: same result- uncertainty magnitude in the Heisenberg uncertainty principle
if smaller: oxygen transport to body cells would be too small and certain life-essential elements would be unstable
if larger: oxygen transport to body cells would be too great and certain life-essential elements would be unstable- cosmological constant
if larger: universe would expand too quickly to form solar-type stars
Ok, I got rid of some of these to simplify things. Btw, all the ones involving radioactive decay rates should just be put down as a general one, seeing as the same physical properties that makes one element decay at a certain rate applies to all elements in a general sense. I do however see some red flags beyond the fact that this is a biased source.
