Sorry, astronomers: the expanding Universe doesn’t match.
The biggest anomaly is the Hubble voltage.
Two methods of measuring the rate of expansion give incompatible values.
The method of primitive relics, via cosmic imperfections, gives 67 km/s/Mpc.
The distance scale method, from individually measured objects, gives 73 km/s/Mpc.
But another anomaly of cosmic imperfection is just as baffling.
Consider the cosmic microwave background (CMB): residual radiation from the Big Bang.
Although generally uniform, one direction is about 3.3 millikelvin warmer while the reverse is also cooler.
This “CMB dipole” reflects the relative motion of our Sun with respect to the CMB: ~370 km/s.
Our local group moves much faster: ~620 km/s.
This should be due to cosmic and gravitational imperfections tugging at us.
Movements of nearby galaxies consistently support this picture.
However, more distant motion tracers come into conflict with it.
Plasmas within clusters indicate smaller global motions: less than ~260 km/s.
The brighter clusters of galaxies, however, reveal larger motions: ~689 km/s.
X-ray emissions reveal giant ones (in the wrong direction!) of ~900 km/s.
And the anisotropies in the number of galaxies reveal more than twice the expected effect.
The number of radio galaxies is even worse: four times the expected amplitude.
WISE’s quasar counts present the same problem.
Future larger-scale investigations may robustly confirm this second “Hubble strain.”
