Over there Hubble constant, or Hubble’s parameter, is a measure of how fast our universe is expanding. This expansion was first demonstrated by Edwin Hubble, using data from Henrietta Leavitt, Vesto Slipher, and others. In the decades that followed, measurements of this expansion settled at a speed of about 73 km/sec/Mpc. A lot of give or take. Astronomers thought that when our measurements became accurate, the different methods would come to a common value, but they didn’t. In fact, in recent years the measurements have become so accurate that I totally disagree with them. This is also known as the cosmic voltage problem.

At this point, the observed values ​​of the Hubble constant are grouped into two groups. Measurements of fluctuations in the cosmic microwave background indicate a lower value, about 67 km/sec/Mpc, while observations of objects such as distant supernovae produce a higher value, around 73 km/sec/Mpc. Something is clearly not right, and theoretical physicists are trying to understand why. This is where themirror universe.

We can create particles of matter in the lab, but when we do, we also create antimatter particles. They always come in pairs. So when the particles formed in the early universe, where did all their antimatter sisters go? One idea was that the universe itself would form as a pair. Our universe of matter is a universe of similar antimatter. Problem solved. The idea fell out of favor for several reasons, but this new study examines how it might solve the Hubble problem.

The team discovered an invariance in what are known as unitless parameters. The best known of these is the fine structure constant, which has a value of about 1/137. Basically you can combine the measured parameters so that all the units cancel each other out so that you get the same number no matter which units you use. The researchers found that when you adjust cosmological models to match observed expansion rates, several unitless parameters remain the same, suggesting that a cosmic symmetry below.

If you enforce this symmetry more broadly, you can scale the gravitational free fall velocity and the photon electron scattering velocity so that the different Hubble measurement methods can match. And if this immutability is real, it implies the existence of a mirror universe that would affect our universe through weak gravity.
