In the article the gas accelerates outward and away from the host galaxy, and winds up far beyond the host galaxy. At the scale of a Universal black hole the gas is now galaxy clusters. The galaxy clusters accelerate outward and away from the Universal black hole.

Our visible universe is in a larger version of the following outflow:





Our Universe looks like the following:

I'm suggesting you read the article linked to in my original post and attempt to conceptualize our visible universe being in the outflow of a Universal black hole.

I'm suggesting dark energy is the outflow of a Universal black hole. There is a singular super-super-supermassive black hole that we are in the outflow of.

All of our visible universe exists in the outflow of the Universal black hole.

, read the article linked to in my original post. The question being asked is why can't dark energy be a larger version of the energy descibed, leaving open the possibility that our Universe is anisotropic.

Low multipoles and other anomalies

With the increasingly precise data provided by WMAP, there have been a number of claims that the CMB exhibits anomalies, such as very large scale anisotropies, anomalous alignments, and non-Gaussian distributions. The most longstanding of these is the low-l multipole controversy. Even in the COBE map, it was observed that the quadrupole (l = 2, spherical harmonic) has a low amplitude compared to the predictions of the Big Bang. In particular, the quadrupole and octupole (l = 3) modes appear to have an unexplained alignment with each other and with both the ecliptic plane and equinoxes, A number of groups have suggested that this could be the signature of new physics at the greatest observable scales

Our being in the outflow of a Universal black hole would explain the following directionality.

New evidence for a preferred direction in spacetime challenges the cosmological principle
