From Wikipedia:
“The Big Bang theory is the prevailing cosmological model for the birth of the universe. It states that at some moment all of space was contained in a single point from which the Universe has been expanding ever since. Modern measurements place this moment at approximately 13.8 billion years ago, which is thus considered the age of the universe. After the initial expansion, the Universe cooled sufficiently to allow the formation of subatomic particles, and later simple atoms. Giant clouds of these primordial elements later coalesced through gravity to form stars and galaxies. The Big Bang theory does not provide any explanation for the initial conditions of the Universe; rather, it describes and explains the general evolution of the Universe going forward from that point on.”

Big Bang is the best theory put forth at present but it does not seem to be the last word.
Did the universe start at the beginning of time, t = 0? Assuming that time could be zero, amounts to thinking of time in absolute terms. The Theory of relativity challenges that notion. From relativistic point of view there is no absolute zero of time.
The universe could be an alternation between expansion and contraction phases.
The universe is essentially motion. The state of motion is called inertia. There is a scale of inertia. As we move toward the high end of the scale, inertia appears as the mass of particles. Inertia increases as mass increases. An example of mass approaching infinity shall be the black hole.
As we move toward the low end of the scale, inertia appears as the frequency of electromagnetic radiation. Inertia decreases as frequency decreases. An example of frequency approaching zero shall be the motion of infinite wavelength. This may be identified as pure space.
At the point of maximum contraction, the universe may appear as having infinite inertia. This condition may appear as a mass particle with a point location. This would be a physical particle that is completely immovable. On the other hand, at the point of maximum expansion, the universe may appear as having zero inertia. This condition may appear as the infinite spread of pure space.
The universe could be oscillating between a point mass of infinite inertia and pure space of infinitesimal inertia.
Therefore “Big Bang” shall occur at the point when the universe transitions from the contracting phase into the expanding phase.
The universe has to be referenced from itself because there is nothing beside the universe. This is where physics transitions into metaphysics.
The conditions of “infinite spread” and “point location” may only be referenced from each other.

I surely like the doctrine of relativism, I like the direction it takes. Relativism seems pertinent and useful for all fields of study.
Supposedly the universe has begun from an “almost” infinitely dense point. This produces more relevant questions about relative relationships such as time vs space vs energy vs mass. I think this holds true socially. Is there any mathematical explanation of what fundamentally causes gravitational forces? Not that they exist, nor that they can be measured, but what fundamentally is going on? Would understanding gravity help understand social attraction?

In my view, gravity would ultimately be explained in terms of inertia (innate state of motion).
Energy is “spread out” state of inertia, whereas mass is “concentrated” state of inertia. Inertia varies very slowly within its phases of “energy” and “mass”. It undergoes a drastic change when phase shifts between “energy” and “mass”. This occurs in the subatomic region.
Time and space are simply the components of motion represented by its period and wavelength. They vary as inertia varies.
Social gravity shall be explainable in terms of social inertia. It is that which keeps the society together in an energetic or massive state.
