Scientists: Quasar data shows time running five times slower in the early universe
The uncertainty of science: According to new research using data from almost 200 quasars collected over the two decades, scientists now believe they have detected the difference between the rate of time now and as we see it in the early universe.
“Looking back to a time when the universe was just over a billion years old, we see time appearing to flow five times slower,” said lead author of the study, Professor Geraint Lewis from the School of Physics and Sydney Institute for Astronomy at the University of Sydney. “If you were there, in this infant universe, one second would seem like one second – but from our position, more than 12 billion years into the future, that early time appears to drag.”
…Professor Lewis worked with astro-statistician Dr Brewer to examine details of 190 quasars observed over two decades. Combining the observations taken at different colours (or wavelengths) – green light, red light and into the infrared – they were able to standardise the ‘ticking’ of each quasar. Through the application of Bayesian analysis, they found the expansion of the universe imprinted on each quasar’s ticking.
“With these exquisite data, we were able to chart the tick of the quasar clocks, revealing the influence of expanding space,” Professor Lewis said.
These results further confirm Einstein’s picture of an expanding universe but contrast earlier studies that had failed to identify the time dilation of distant quasars. [emphasis mine]
I have highlighted the word “exquisite” because it is a favorite buzzword of scientists when they are trying to oversell conclusions that carry many uncertainties. As good as this data might be, it is still incredibly sparse, and the interpretation of it requires many assumptions.
Nonetheless, these results are likely correct, in some manner, because they match well with Einstein’s predictions. It is also most likely that there are many errors and incorrect aspects to those results that the scientists do not yet understand. Above all, confirmation bias remains a concern.
The support of my readers through the years has given me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Four years ago, just before the 2020 election I wrote that Joe Biden's mental health was suspect. Only in this year has the propaganda mainstream media decided to recognize that basic fact.
Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Even today NASA and Congress refuse to recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.

Does the Past Still Exist?

I just want to add a recommendation to Dr. Sabine Hossenfelder! She is obviously a bright woman in the area of theoretical physics.
Sabine is pronounced “Sah-BEEN-ah”, by the way.
I used to follow “Dr. Becky” the astrophysicist on YouTube, but frankly her cutesy ways ended up turning me off – she seems to think that being a female media personality means you have to smirk and giggle a lot!
Sabine H. manages to be charming but not cloyingly so.
Ray–
Tangentially– Dr. Brian Keating can be very humorous in a low key manner.
(Dr. Richard Feynman– he loved strip-clubs & practical jokes.)
–I’ve watched Dr. Becky before, and while she’s very pleasing to the eye, yes– a bit too much smirking & giggling going on.
Here we go….

Were you aware Sabine also does music-videos & sings? Apparently, it confused her audience and the YT algorithm, so she separated her physics & music videos.
