I know nothing about physics really, but I get on kicks that I can't stop wondering about, most of which are nothing short of silly I'm sure. Well here's one that I would love someone's indulgence in a response to:
I am a FIRM believer in equal and opposite, I think no matter what we learn about anything that will be rule #1, or close to it. That being said, I think they say just after the big bang the universe was out of balance where heavier particles attracted others and so on, or that the Higgs boson they are using the LHC to look for that was so heavy it fell apart to create stuff that would attract and so on. Again, I don't know if I'm still making sense, but, by any means if things came apart at the very beginning wouldn't they want to revert to their natural state and come together? Ultimately my main question is, could gravity be the reaction to either the early universe falling apart (being so long ago going towards why gravity is so weak), or to the universal expansion itself? I have read a bit on the idea of gravity "Leaked" out of another dimension, but I don't think so.

Thanks for your time and patience. :)

I don't know if gravity is considered a reaction to anything. It's just a force relative to mass, velocity etc.

As the universe expands and adds space between masses, the force of gravity is naturally weakened (which is what I think you're talking about).
 
I started reading a National Geographic article related to the Big Bang. It starts these statements: Gazing up at the stars at night, it’s easy to imagine that space goes on forever. But cosmologists know that the universe actually has limits. First, their best models indicate that space and time had a beginning, a subatomic point called a singularity. This point of intense heat and density rapidly ballooned outward. My first reaction was that this is a layman's approximation to...
Thread 'Dirac's integral for the energy-momentum of the gravitational field'
See Dirac's brief treatment of the energy-momentum pseudo-tensor in the attached picture. Dirac is presumably integrating eq. (31.2) over the 4D "hypercylinder" defined by ##T_1 \le x^0 \le T_2## and ##\mathbf{|x|} \le R##, where ##R## is sufficiently large to include all the matter-energy fields in the system. Then \begin{align} 0 &= \int_V \left[ ({t_\mu}^\nu + T_\mu^\nu)\sqrt{-g}\, \right]_{,\nu} d^4 x = \int_{\partial V} ({t_\mu}^\nu + T_\mu^\nu)\sqrt{-g} \, dS_\nu \nonumber\\ &= \left(...
In Philippe G. Ciarlet's book 'An introduction to differential geometry', He gives the integrability conditions of the differential equations like this: $$ \partial_{i} F_{lj}=L^p_{ij} F_{lp},\,\,\,F_{ij}(x_0)=F^0_{ij}. $$ The integrability conditions for the existence of a global solution ##F_{lj}## is: $$ R^i_{jkl}\equiv\partial_k L^i_{jl}-\partial_l L^i_{jk}+L^h_{jl} L^i_{hk}-L^h_{jk} L^i_{hl}=0 $$ Then from the equation: $$\nabla_b e_a= \Gamma^c_{ab} e_c$$ Using cartesian basis ## e_I...
