I am now in the third week of my annual February birthday fund-raising drive. The first two weeks were good, but not record-setting.


There are still two weeks left in this campaign however. If you have been a regular reader and a fan of my work and have not yet donated or subscribed, please consider doing so. I take no ads, I keep the website clean from pop-ups and annoying demands (most of the time). Thus, I depend entirely on my readers to support me. Though this means I am sacrificing some income, it also means that I remain entirely independent from outside pressure. By depending solely on donations and subscriptions from my readers, no one can threaten me with censorship. You don't like what I write, you can simply go elsewhere.


You can support me either by giving a one-time contribution or a regular subscription. There are five ways of doing so:


1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.


2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.

3. A Paypal Donation:

4. A Paypal subscription:

5. Donate by check, payable to Robert Zimmerman and mailed to

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.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.

The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

    Does the Past Still Exist?
    Sabine Hossenfelder (July, 2022)

    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.

  • wayne

    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….

    “Time Ran Slower in Early Universe, New Study Finds”
    Sabine Hossenfelder (7/5/23)

    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.
