THE ELEMENTAL FORCES OF THE UNIVERSE
At the temperatures common to our world, four discrete forces govern the interactions of matter - gravity, electromagnetism, the weak nuclear force, and the strong nuclear force. Though these four forces govern every matter interaction, a theory that unites them all is still being sought. The most recent candidate is string theory.
In order from strongest to weakest:
1. Strong Nuclear Force: Operates on extremely small nuclear scales, responsible for keeping the quarks in protons and neutrons together.
(Holds atoms together)
2. Electromagnetic Force: No chemical bonds could form if it were different.
(Electricity, magnetism, light)
3. Weak Nuclear Force: responsible for radioactive decay in particles, as well as certain interactions between particles. Operates on small nuclear scale.
(Radioactive decay)
4. Gravity is the weakest force in the universe, yet it is in perfect balance. Law of gravity: All masses are found to attract one another with a force that varies inversely as the square of the separation distance between the masses. (Makes matter attract each other)
Messenger Particles
Each force is carried by a separate "messenger particle" unique to it and still being researched. Experiments have confirmed the existence of three of the four particles, but the graviton has yet to be discovered. Calculations show that it should be massless.

Scientists speak about the Perfect Order of the Universe.
It is of interest that, in spite of the delicate internal ratio balance within each of the four forces (gravitation, electromagnetism, and the weak and strong forces), those four forces have strengths which differ so greatly from one another that the strongest is ten thousand billion times more powerful than the weakest of them. Yet evolutionary theory requires that all four forces originally had to be the same in strength—during and just after the Big Bang occurred!
It should also be noted that evolutionists cannot claim that these delicate balances occurred as a result of "natural selection" or "mutations"! We are here dealing with the basic properties of matter. The fundamental forces are what they have always been what they were since the Beginning! They have not changed, and they never will change. It began just right; there was no second chance! The same with all the other factors and balances
