There seems still reason for smaller scale building blocks of Q-FFF Strings.

IF we accept the observed NANOGrav monster black holes in the primordial universe coming from the cyclic multiverse,

Then there seems still reason for smaller scale building blocks of Q-FFF Strings coming out of the Big Bang as packed together by the oscillating dark energy vacuum as massive Black Hole chunks. (the largest we observe in NANOGrav.)

Second conclusion: 

Gravity is a vacuum pressure force (Axion) compensated by the diluted opposite coming Axions through the Earth, partly changed into Gravitons and other photons.

Secondly, There seems also reason for smaller scale building blocks of Q-FFF Strings: reason: the ability to form transformable Strings constructed by 4x elbow macaroni shaped parts connected by 4x Hinges each with a 90 degree click stop.

The base for the mechanical particle topology based Form Follows Function universe. (Q-FFF) .

However each seems to be guided by a 12x mirror multiverse semi instant entanglement. (SUSY : semi instant multiple entanglement according to B. Libet (RPI -RPII 300-800 msec = uncertainty base) and J.Cramer.:   https://vixra.org/pdf/1907.0250v3.pdf ))
