what forces were present before creation of universe which in relation made other forces such as gravitational

At high enough energies the weak force and the electromagnetic force combine (only observed fairly recently), which gives us three forces: electroweak, strong, and gravitational. The theory is that the strong and the electroweak force also combine at even higher energies (which we have not achieved in particle accelerators yet). Since the gravitational force is so weak, it's hard to say if that can also be incorporated into the strong-electroweak force lol. I assume at insanely high energies (that existed during the creation of the universe in the big bang) this is very possible though. So there probably was one force, which split into other ones once the energies got less (after fractions of a second).

For your theory to work some 'thing' must exist before the Big Bang event and in which it could occur. Science has found absolutely no evidence whatsoever that any 'thing' preceded the Big Bang.

It could have been the force resulting from a universal collapse just before.\n\nIf you're a religious person, then maybe it was God.

i think the problem is when you try to apply general relativity - or gravity - to interaction betwen subatomic particles - especially when trying to understand how these forces worked during the first instant after the big bang. you wind up with nonsencial results - like zero equals one.

Its origins and nature are still open to postulation. But it is an attractive force only between any two masses and Newton concluded in his uneiversal laws of gravitation that the attractive force (F) was proportional to the masses interacting(M1 and M2) and inversely proportional to the square of their distance apart (r)\n\nie F α M1*M2/d²\nwhence \n\nF = G*M1*M2/r² \nwhere G is the universal gravitation constant\nG ≈ 6.6742 x 10^(-11) Nm²/kg²

Nuclear force, gravitational force, (I think these can be either attractive or repulsive:) electrostatic force, and magnetic force.

Either answer would be wrong.  The universe came first.

As objects move closer together, the gravitaional forces betwen them increase.  That is to say, the gravitational force is inversely proportional to the distance betwen the objects.\n\nA reduction of distance by a factor of 5 would mean a five fold increase in the gravitational force.

L = 8pi G rho/c^4 is the definition of the cosmo constant L (1/m^2); where c = light speed and rho is the energy density of the known universe in a vacuum.\n\nF = GmM/r^2 is the equation for the attraction force F between two masses m and M, r distance apart.\n\nL was created by Einstein to make his equations come out right.  By that, he meant the universe should be spherical (not flat or saddle shaped).  His original results showed a flat universe, and he just "knew" that was wrong; so on came L to fix the shape problem.\n\nF was the result of experiments by Newton.  Through observation, he found that the attractive force between two bodies was proportional to the inverse square of the distance between them and to the product of the magnitudes of the two masses.  That is, F varies as (~) (mV/r^2).  \n\nWhenever there is a proportionality, as in F ~ mM/r^2, there has to be a constant of proportionality.  In this case Newton called it G; so that F ~ mM/r^2 becomes F = GmM/r^2 when the constant is inserted.\n\nThe G in both equations is the same constant.  But Sir Newton came upon it long before Einstein found it could be used in his equations and the calculation of L.  So there is no way that Newton (1642-1727) could know about Einstein's (1879-1955) use of it much later.

Anew theory of gravity as well as a unified field theory (UFT) are being proposed, showing how the four force fields work together, implicating also a fifth field. A main feature of this new model is the proposal of the existence of diallel, gravitational-field lines that emanate from every entity. For the earth, for example, they emanate radially from its center. These diallel lines provide a conduit for combined particle and wave flow and exchange beyond the speed of light, and they have quantum states similar to the atom. On the web site, we present a general field equation showing the importance of energy density in this new UFT. We also present a new gravitational force equation, that has as a special case the commonly accepted gravitational equation.

the gravitational force can act in any medium as well as in vacuum. the sun exerts a gravitational force on the earth across a vast expanse of vacuum! this itself is proof enough.\nthe objects will all touch the ground at the same time whether in a medium or in vacuum. this occurs for the sole reason tht all of them are of equal mass.

The four fundamental forces are:\n\n1-Gravitational Force\n2-Electromagnetic Force (the force between charged particles - the photon is the mediator of this force)\n3-Strong (nuclear) Force - keeps nuclei bound together\n4-Weak Force (responsible for Beta decay of the nucleus)

Yes, a gravitational field can and does exist within other gravitational fields.  All masses in the universe exert an attractive force on all other masses in the universe through a force known as gravity.  Gravity is a vector quantity meaning it has a direction.  These forces act in different directions and cancel each other out. To keep from getting too technical take this example.\nYou are standing on the surface of the Earth, within its gravitational field.  The Earth attracts you to its surface because of the force known as gravity. You, having mass, also exert a force of attraction on the Earth. The reason you do not notice your attractive force on the Earth is that the earth's mass is so much larger than your own. The earth acts a force in one direction, you act a force in the opposite, the result is the net force in the system.(You bening pulled toward the larger mass, Earth)\nThis can be proven mathematically with the formula \nFg=[G(me)(m)]/d^2\n\nG being the gravitational constant, multiplied by me, representing the mass of the earth, and multiplied by m, representing your mass, divided by the distance between you and the earth's center of gravity squared.

This is a question that neither science or religion can ever "prove."  In our human capacity, it is unlikely anyone will ever know the answer to this.  How can you even take a scientific approach to this?  You can speculate how the universe appears to be created based off measurements in the space, but you can always ask the question "but what about before that?"  \n\nUltimately it comes down to faith, and I don't necessarily mean in a God.  You have faith that the universe was started somehow.  Either God or some unexplainable cosmic phenomenon that we will never understand.  Or both!

I'm anxious to hear if any scientists have an answer to this question.  To me, it sounds like you're asking "Who initiated the Big Bang?" or "Why does gravity cause matter to be attracted to other matter?"  It seems to me like the question of "Why?" neutrons have neutral charges is kind of a God question.

The same 4 fundamental forces in the universe: Strong, weak, electromagnetic and gravity. Of course, it should be noted that we have made substantial progress into showing that the weak and electromagnetic forces are two aspects of the same force, and that even the strong force can be associated very closely with the electroweak force. There are many attempts to connect all 4 forces into one universal force law, but this effort is not yet complete and the results are not yet universally accepted. \n\nThere are some indications that we do not really understand gravity very well, because we do not understand its quantum aspects too well, and there is even evidence emergy for some sort of repulsive gravitational phenomenon from astronomical observations. \n\nThe discovery of any other forces would be quite surprising, and very big news.

No energy source? What source of energy is needed? And the simple presence of mass causes gravitons. And these gravitons interact with one another. And proof, you need proof that gravity works? Dude go jump off of a building and see what happens!
