The Magnetic Universe — it's Electric! | Space News
excerpt from header:
Today, in mainstream astronomical literature we hear more and more about the "Magnetic Universe." Thanks to great technological leaps, scientists have learned that vast magnetic fields pervade the cosmos, and increasingly, cosmologists view magnetism as important in the formation and evolution of structures at all cosmic scales.
Beginning at about 10:30
There are questionable statements.
Arp concluded quasars red shifts were associated with age because he used a limited set of low red shift quasars, all with z<2 and low red shift galaxies, at all z < 1. This scenario shown at 10:30, and again at 10:40. A galaxy pair is shown with A z = 0.029, B z = 0.057
They are compared to quasars with larger red shifts but all values are small.
Since Arp's efforts, many galaxy and quasar z values are often z> 2. The highest red shifts are z > 7.
Arp's conclusions about age came from a very distorted data set, so they are not valid.
At about 10:47, there is another mistake.
Red shifts are NOT intrinsic to galaxies.
The image shows galaxies from Virgo and Ursa Major with larger red shifts, than Arp.
22000,km/s is z=0.07 so this galaxy red sgift is greater than Arp's lowred shift galaxies compared to higher quasar red shifts.
There is a distinct pair of absorption lines in each spectrum.
That pair is the pair of the calcium ion absorption lines, identified by "H & K" which are the names of the 2 lines. Only hydrogen has a single absorption line because it has only one electron. A calcium atom has 20.
A quick look of the coarse images reveals only the pair is shifting but not the rest of the spectrum including the ends.
Therefore, only the ions are moving not the galaxy. Galaxies never exhibit a Doppler effect because only a star is an original light source. The observed red shift is NOT intrinsic but is instead is from atoms in the line of sight.
An analysis of the entire galaxy spectrum is required to determine whether all of it is shifted from this galaxy being at rest in this line of sight. A Doppler effect does not shift only one or two wavelengths from the light source.
I have posted numerous times about the 2 different red shifts for a galaxy: 1) hydrogen absorption.
2) metallic absorption.
This figure shows all its galaxies with the metallic absorption red shift from calcium.
Arp had low red shift quasars with low red shift galaxies. With no spectra, One can assume all of Arp's galaxies were hydrogen red shifts caused by the IGM.
The video proceeds with no explanation for the galaxy red shifts just presented.
At about 11:30, the study of supernova type Ia is described.
This part of the video missed the mistake in the study.
When one closely examines that study, as I did, the researchers found the light curves from their many objects were rather consistent. They incorrectly assumed they were supernovae.
One sees them decreasing just like a variable star's luminosity curve. In the paper, a sample spectrum from one of the claimed supernova matches the spectrum change expected for a Cepheid variable.
None of the objects had an abrupt brightening which should be expected from a supernova.
The supernova study concluding the universe is expanded based on variable stars, NOT supernova.
They made another mistake assuming the galaxy red shift was directly related to the age of the galaxy. That assumption cannot be justified.
This supernova study must be ignored given its fundamental mistakes with its assumptions for its data.
The video makes valid points along the way but the middle involving quasars makes mistakes. The supernova study was mishandled.
