If gravity were light, the sky would be uniformly blinding bright.

Photons must exceed minimal threshold energy in order to be absorbed and detected by any means. Consequently, that same minimal energy must be involved in generation for the product to qualify as a detectable photon.  The thresholds exist because the generation and detection processes involve work.

Gravity links on the other hand, can join two bodies without necessarily any work being performed.  Individual gravity links exert a miniscule pull but unlike light, every one counts and collectively they can indeed be formidable. 

There is still a significant number of stars way out there whose light simply has not had time to reach us yet. 

The pull of gravity is a very different phenomenon to light or even gravity waves which can propagate no faster than c.  Photons are transverse pulses that can flex links only so fast.  Most gravity links however, do not have to propagate far.  Link segments are already there!  Most simply put, we don’t have to wait for gravity from stars whose light has not reached us yet.  Would all Relativists now please take a deep breath (and keep reading)?

Gravity from those most distant stars linked with particles in our bodies before they became stars and long before we became us.  Links were established and grew with the universe, right from the beginning.  The net result is a “pre-wired” cosmos in which an average number of links always exists. 

Would you run a new wire every time between your house and everybody you talk to?   It just does not make sense to run a new wire to the other side of town, then for the next call run one all the way to Kalamazoo!   Thank goodness for the invention of the Public Switched Telephone Network and later, the Internet.

As usual, nature did it first.  Gravity links are not continually re-created over vast distances.  When a link between earth and the sun breaks, we do not wait 8 minutes for a replacement!  If the break was close to the sun, a new link melds onto the end of another one that already covers the rest of the distance.  The net result is that gravity links fail and new ones are established over billions of light years almost instantly.  Now it should be clear why a little neutron can fill its huge complement of gravity links to any of an infinite number of stars in the universe.

Telescopes compensate for limitations of the eye and have managed to collect and detect light from stars as much as 8 billion light years away.  The human eye on its own however, is subject to an even higher detection threshold. 

For the human visual system to even just barely detect one dot of light, several photons are required.  Light from a more distant star has spread out too much before reaching earth.

The probability of multiple photons from the same distant star taking just the right path at the same time, and hitting your eye is slim.  The more distant stars are therefore too dim to see. 

Even this group of stars is still effective for gravity however; because again, every little bit counts.  Without being eliminated at either threshold, every gravity link can contribute to a collective pull.  

Even if multiple photons from the same distant star take just the right path at the same time and do hit your eye, you still probably will not see it.   The photons are random in phase and their energies partially cancelling can result in missing the atomic detection threshold and/or the visual threshold. 

This does not apply to gravity.  The author predicts that gravity waves will never be detected from a celestial body.  Gravity waves do not get far without mutual reinforcement as is the case between fields in electromagnetic propagation.

The virtually instant establishment of gravity links does not change existing general relativity theory one iota!  The concept however needs to be added to make the theory complete.

Because it is so fast, time does not really enter the picture and links are established in Euclidean planar space.   This establishment phase and general relativity are not mutually exclusive.  

It is already done before GR even ‘knows’ about it.  As far as GR is concerned, everything occurs as expected.  The instantly established links produce a warp in space-time that extends at light speed.  Gravity continues to be felt as per GR field equations.

Any rapid acceleration or sudden displacement of a body also then propagates along the links at light speed (i.e. gravitational radiation).

The pull of gravity is not accomplished with “exchange particles” that are discrete in space and time.  Firing “particles” at each other, bodies would actually separate.  Something is of course going on and you could call it “anything” in a physical model without affecting any quantum equations that may be developed for gravity.  

The only model that makes sense is the energy link that exists as a continuous line in space.  Because energy links are so thin they can be considered one-dimensional, and are unlikely to be measurable in the foreseeable future.  They are nevertheless, the separate quanta of gravity.
