The first study reports new measurements made on a star called HD 140283.[1] This “Methuselah” star, located only 190 light-years away from us, is estimated to be 14.4 ± 0.8 Gyr-old.[3][4] The improvement in the estimate of its age results from a more accurately known distance to the star obtained from parallax measurements using the Hubble Space Telescope. The more accurate determination allows a better measurement of its absolute luminosity. Using the luminosity, the known composition of the star from spectroscopic data and temperature measurements, models of stellar formation allow a reevaluation of its age.
This result is important because the estimated age of this star, which has been a problem for decades, is now almost compatible with the age of the universe. In 2000, the estimated age of HD 140283 was 16 Gyr![4] In the last decade, star evolution theories have been revised to be consistent with the 13.8 Gyr limit.
But no matter how much anti-wrinkle cream astronomers and stellar physicists have put on this star, it still looks too old. An age of 14.4 ± 0.8 Gyr gives it an 89% chance that it is older than the Universe. Although one measurement does not have statistical significance, there have been many studies on globular clusters containing hundreds of thousand of stars. Age estimates of globular clusters range from 11 Gyr to the very problematic 18 Gyr.[5]
The second study, published in Nature on March 13th,[2] shows starburst galaxies as early as 1Gyr after the Big Bang.[6][7] These new results come from the Atacama Large Millimeter Array (ALMA), a group of radio telescope which has the sensitivity and resolution to detect extremely faint objects at large distances. By using detection at long wavelengths, ALMA has the advantage of looking at radiation which is not absorbed by the intergalactic medium as easily as visible light.
A foreground galaxy photographed with the Hubble Space Telescope (greyscale) acts as a lens to enhance the image of a starburst galaxy detected with ALMA at 0.87mm (red). This representation is based on the images in Ref. [2]. SPT 0243-49 has the highest redshift of all sources reported by Vieira et al.
Starburst galaxies are very active and produce stars at a very rapid rate. Large quantities of gas and dust are required to feed these monsters and it is expected that a long time must have elapsed after the Big Bang to accumulate all this material. The paper reports galaxies with star-formation rates in excess of 500 solar masses per year. Says the leader of the study J.D. Vieira: “We were very surprised to find galaxies like this so early in the history of the universe.“[6] Such a surprise only points out the weaknesses of the standard cosmological model and the underestimated age of the Universe.
Commentary:
These are only two of the most recently reported cosmological surprises. One will recall the grand-design spiral galaxy which already existed 3 billion years after the Big Bang[9] and the metal-rich galaxies seen only 1.8 Gyr after Big Bang.[10]
How many more “surprises” will it take before cosmologists start having serious doubts about Big Bang? It is becoming clear that the interpretation of the redshift as the expansion of the Universe and the CMBR seen as a relic of the Big Bang are failing models.
Cosmologists argue that all alternate cosmologies to the standard cosmology have been rejected, but this is no longer the case. Based on new theories of radiation cooling developed in the last two decades,[11] a spectral redshift can be explained as a quantum effect on gases and electrons.[12] The CMBR results from the thermodynamic equilibrium of radiation with the intergalactic medium. When radiation passes through warmer galaxy clusters, it acquires some energy which results in a ‘blue-shift’ of the spectrum. This is thought to result from the Sunyaev-Zel’dovich effect,[13] but the quantum description of the ponderomotive force on electrons also reproduces the observed spectra.
“ALMA is so sensitive, it is going to change our view of the universe in many different ways…” says Vieira. This certainly is an understatement as cosmology is about to see the demise of a theory which is on its last legs!

“The notion that the universe is expanding is based on the classic interpretation of the redshift and blueshift effects, but if QGD is correct and redshift and blueshift effects are consequences of the stage of evolution of their source, then the expanding universe model loses its most important argument. The data then becomes consistent with the locally condensing universe proposed by quantum-geometry dynamics.”

Dark Matter doesn’t exist and has not been detected. Matter manifests gravity. The over gravity rotation is not of that gravity, velocity reflecting the square root of matter. The over rotation is due to electromagnetic forces produced by homopolar motors. Galxies rotate by gravity as a slow speed. The masses are positively chatged and the rotation caused a circular current producing a magnetic B-field perpendicular to the plane.
Intergalactic electron flows into the galaxy. This produce a radial force eVxB=VxP/r.
The Momentum P=mV = eBr=euI, the Velocity V = (e/m)uI =( 176G) 1.25u I = =220Ikm/s. The electromagnetic force velocity is 220km/s per 1 amp of current.
Highly charged masses like bright suns move faster, dark less charged suns will be slower. This is the pattern. The strength of the B-Magnetic field will be strongest in the center and create jets of electromagnetic radiation and arcing.
This is the likely the “missing matter” not Dark matter. This is driven by electrons flow into galaxies. Hubble Pictures show the Universe is lit up like neon lights, electrons flowing in electric fields.
The “age” of the Universe is 15.844 Gy.
