People have been exagerrating stories for millenia, exagerating claims and inventing stories just like today. It helps with fundraising for pet theories and gaining social status and controlling public thought.
This immediately means that as the universe expands , the objects within it should all expand right along with it . THEY DO NOT !
To be honest I am not sure if this question has any validity. I am thinking of what state would the vacuum be in before the big bang. Did it exist?
I don't see why you would.
The quanta of the field are distinct from the field itself. It is the energy of the field that I mean as opposed to the energy of the quanta.
As far as Chris Baird is concerned I haven't followed any link to his opinions. So I can't comment onI was referring only to the quote:”… the influence of gravity only extends to the edge of each galaxy group. Beyond that, spacetime no longer behaves like gravity.”
that.
However, the gravitational field does not exist in isolation and other fields/forces must be taken into consideration. These may in some cases not only cancel the effects of gravity but also cause a repulsive force.
How can objects be separated by an infinite distance if infinity is not a number?
If they can't then the gravitational field can approach infinity but never actually reach it.
This means that the potential of the gravitational field never increases to a zero value.
However it can get immeasurably close to zero.
How does a graviton get out of a blackhole if it has too little energy to detect it ?? .
Gravity travels at the speed of light (in a vacuum). So for the moment before Cosmic Inflation, all matter was in the gravitational field of all other matter. This situation did not hold after Cosmic Inflation, nor does it hold for parts of the universe that are now beyond our Visible Universe.
Gravity obeys the inverse square law. It becomes arbitrarily weak with distances but its strength never goes to zero. At least as best as we can tell.
There is nowhere where you have zero gravitational potential energy.
…….. certainly galaxy superclusters have an effect on each other….
Both space and time appear to be emergent phenomina based on entanglement perhaps
Yes, gravity is a force. But it is a force that is more completely described by spacetime curvature and not Newton's law. The fact that gravity is caused by spacetime curvature means ultimately that it can be viewed as an inertial force, meaning that it arises from the inertia of an object as viewed from a non-inertial frame. But it is indeed a real force. It's not just a classical force. You will see some places call it a "fictitious force" which can be misleading. The word fictitious is not used by physicists in this context to mean fake, imaginary, or pretend. Rather it means that the force arises from the way the inertia of an object is being viewed in a non-inertial frame. For instance, the centrifugal force is a "fictitious" force, but it is a very really force indeed in the rotating reference frame which leads to measurable physical effects.
It's tricky Bill
I am strugling to find an actual qoute
BUT qouting from wikiqoute "Gravity is most accurately described by Albert Einstein's general theory of relativity, which describes gravity not as a force but as a consequence of the curvature of spacetime....
: did you have any particular “bang” in mind? 
So, is it feasible to create higgs boson by pure/infinite energy, without using accelerator and magnetic power?
