The last and most important question is: How this particular, purported quantum gravity, while not being a fundamental force, and therefore not having its own autonomous field with its corresponding particle, would be able to propagate in the intergalactic space?
This is possible due to intergalactic cluster’s magnetic fields. At this point, it is a conjecture that it could, and should also have something to do with quantum vacuum as an intergalactic physical medium, with quantum vacuum polarization, and with quantum entanglement.
Astronomers have observed a cluster of galaxies being pulled in by a mysterious force
The Magellanic Bridge :
Astronomers have detected a magnetic field associated with the Magellanic Bridge, the filament of gas stretching 75 thousand light-years between the Milky Way Galaxy’s nearest galactic neighbours, the Large and Small Magellanic Clouds

Galactic and intergalactic magnetic fields; Proceedings of the 140th Symposium of the International Astronomical Union
The present conference on galactic and intergalactic magnetic fields (MF) encompasses a survey of magnetic phenomena near the solar photosphere, the MF structure of the Galaxy, MFs in and around supernova remnants, magnetohydrodynamics of galactic MFs, the MF structure of external spiral galaxies, and MFs in molecular clouds. Also addressed are MFs in galactic nuclei, the role of MFs in radio-source jets, MFs in the galactic environment, MFs in the early universe, MFs at high redshifts, MFs in galaxy clusters and intergalactic medium, the role of MFs in extended radio lobes, and MFs in dark globules and the prestellar and circumstellar environment. Specific issues addressed include a coronal magnetic structures observing campaign, phenomena involving magnetic vortex tubes.
An analogy for intergalactic toroidal magnetic vortex tubes:
An electric current of five million amperes flows along moon Io’s flux tube. It connects moon Io to the upper atmosphere of Jupiter, like a giant umbilical cord. The plasma torus is centered near Io’s orbit, and it is about as thick as Jupiter is wide. The torus is filled with energetic sulfur and oxygen ions that have a temperature of about 100 thousand kelvin. Because the planet’s rotational axis is tilted with respect to the magnetic axis, the Io’s orbit is inclined to the plasma torus. Currents are generated as the plasma from the Io torus spreads into the vast, rotating magnetosphere of Jupiter, and these currents couple the moon to Jupiter’s atmosphere where they stimulate a ring, or oval, of aurora emissions.
