Note how the following elements or items are presented. For example, the first item, the 'Strong nuclear force,' if it was very slightly greater, would result in the effects described against the plus (+) sign; and if it was very slightly smaller, this would result in the effects described against the minus (-) sign; and so on for each of the remaining items.

Strong nuclear force 
   +   no hydrogen would form; atomic nuclei for life-essential elements would be unstable; life would not be possible
   –   no elements heavier than hydrogen would exist: life would not be possible

Weak nuclear force constant
   +   too much hydrogen would convert to helium; stars would convert too much matter into heavy elements; life would not be possible
   –   too little helium would be produced; stars would convert too little matter into heavy elements; life would not be possible

Strength of force of gravity at all time stages of universe
   +   stars would be too hot and would burn too rapidly and too unevenly 
   –   stars would be too cool for nuclear fusion; elements needed for life would never exist

Strength of force of gravity at all size stages of universe
   +   gravity would overwhelm the expansion of the universe and fatal contraction would occur 
   –   gaseous nebulae would never succeed in forming stars; preventing life

Electromagnetic force
   +   chemical bonding would not occur; essential elements would be unstable
   –  chemical bonding would be unstable and life would not be possible

Ratio of electromagnetic force to gravitational force
   +   all stars would be at least 1.4 times the mass of our stable sun; life-cycle of stars would be too brief to support life 
   –   all stars would be at least one fifth the mass of the sun, making them incapable of producing heavy elements

Mass of the neutrino
   +   If neutrinos have even a small amount of mass, their high density throughout the universe would increase the Omega value (the mass in the universe) causing its eventual collapse; galaxy clusters and galaxies would be too dense, making conditions impossible for sustained, comfortable life
   –   If Omega (the mass in the universe) is infinitesimally less than 1.0, it would be unable to prevent the universe from expanding forever; galaxy clusters, galaxies, and stars would not form

The lambda particle
   +   If lambda ("vacuum energy" or "quintessence") is non-zero, universal expansion may be accelerating
   –   If lambda is zero, the universe may easily collapse

Ratio of electron to proton mass
   +   chemical bonds would be too few, meaning life would not be possible
   –   chemical bonds would be unstable, meaning life would not be possible

Ratio of number of protons to number of electrons
   +   electromagnetic force would be too great for gravity, preventing formation of galaxies, stars, planets 
   –   electromagnetic force would be inadequate … stars would never form

Expansion rate of the universe
   +   no galaxies would exist
   –   universe would quickly collapse

Entropy level of the universe
   +   stars would not exist within proto-galaxies
   –   proto-galaxies would not exist

Mass density of the universe
   +   excess of deuterium (in contrast to helium) would mean stars would burn out too rapidly for life to exist
   –   insufficient helium would mean shortage of heavier elements essential for life

Velocity of light
   +   stars would be too bright
   –   stars would be too dark

Age of the universe
   +   no stars sufficiently stable would exist in required locations of the galaxy
   –   stable stars would not have formed

Initial uniformity of radiation
   +   if more uniform: stars, star clusters, galaxies and galactic clusters could never form
   –   if less uniform: the universe would quickly have become “over-run” with black holes and be predominantly devoid of stars essential for life

Distance of moon from the earth
   +   If much closer, tidal waves would be 1,000 times greater than they are today
   –   If much further away, earth's day would be only 8 hours long; winds and hurricanes would be considerably greater; oceans would not be chemical-rich and therefore inadequate for life 

Distance of earth from the sun
   +   Freezing temperatures would not permit life to survive, or even to develop
   –   Heat would scorch the atmosphere, as well as land; oceans would be evaporated, and no chemicals required for life-synthesis would exist

Size of the moon
   +   Sun's gravitational effect on the moon (currently about twice that of the earth) would be greater, causing severe irregularities in moon's orbit with consequences like those explained for 'Distance of moon from the earth'
   –   The moon would have less mass and would therefore draw rapidly closer to the earth; earth’s day would be only about two thirds its current length; less scattered sunlight; greater seasonal fluctuations; life would be uncomfortable

Average distance between stars
   +   heavy element density would be too sparse for rocky planets to form
   –  planetary orbits would be too unstable for life

Average distance between galaxies
   +   lack of material for star formation
   –   gravitational effects would destabilize the sun's orbit

Density of galactic cluster
   +   galaxy collisions and mergers would destabilize the sun's orbit
   –   lack of material for star formation

Fine structure constant
   +   too many stars would have significantly less mass than the sun; matter would be unstable in large magnetic fields
   –   all stars would have significantly greater mass than the sun, decreasing the chances of an adequate “goldilocks” distance

Decay rate of protons
   +   radiation would prevent the existence of life
   –   universe would contain insufficient matter for life

Ratio of neutron mass to proton mass
   +   neutron decay would yield too few neutrons for the formation of many life-essential elements
   –   neutron decay would produce so many neutrons that stars would collapse into neutron stars or black holes

Initial excess of nucleons over anti-nucleons
   +   radiation would prohibit planet formation
   –  availability of matter would be insufficient for galaxy or star formation

Supernovae eruptions
   +   if too distant, too infrequent, or too soon: heavy elements would be too sparse for rocky planets to form, hence life would not be possible
   –   if too close, too frequent, or too late: radiation would prevent life from existing for sufficient time

White dwarf binaries - quantity
   +   if too many: planetary orbits would be too unstable for life
   –   if too few: insufficient fluorine would exist for life chemistry

White dwarf binaries - timing
   +   if formed too late: fluorine would arrive too late for life chemistry 
   –   if formed too soon: insufficient fluorine production

Ratio of exotic matter mass to ordinary matter mass
   +   universe would collapse before solar-type stars could form
   –   no galaxies would form

Number of dimensions in early universe
   +   quantum mechanics, gravity, and relativity could not coexist; life would be impossible
   –   same result

Number of dimensions in present universe
   –   quantum mechanics, gravity, and relativity could not coexist; life would be impossible
   +   electron, planet, and star orbits would be unstable, preventing life

Big bang ripples
   +   galaxies/galaxy clusters would be too dense for life; black holes would dominate; universe would collapse even before life-site could form
   –   galaxies would not form; universe would expand too rapidly

Cosmological constant
   +   universe would expand too quickly to form stars capable of sustaining life
   –   the expansion rate of the universe would be slower; the universe would quickly collapse or too much time would be allowed for gravitational forces to pull matter together, leading to denser and more numerous structures, and making gravitational forces too great either for life to exist comfortably or even for life to begin at all
