Webb discovers another “oldest black hole”The uncertainty of science: Using the Webb Space Telescope, astronomers now claim they have detected a super-massive black hole at a new record-setting distance that puts it far closer to the Big Bang that cosmologists have predicted.
A global team of astronomers, led by The University of Texas at Austin’s Cosmic Frontier Center, has confirmed the discovery of the most distant black hole ever observed. This black hole resides within a galaxy known as CAPERS-LRD-z9, which existed only 500 million years after the Big Bang.
In other words, the light we see from it has traveled 13.3 billion years, revealing the universe at just 3% of its current age.
The black hole, estimated to have the mass of 300 million suns, sits in the center of one of the mysterious “little red dots” that Webb has discovered in the early universe that remain a mystery. This black hole suggests each is an early galaxy with its own super-massive black holes.
I must note that there is great uncertainty in the claim of a black hole discovery. It is based on the spectroscopic emissions detected by Webb, which had features generally seen only in super-massive black holes in the recent universe. Thus, the scientists are making some large assumptions in concluding those emissions also indicate a super-massive black hole in this little red dot.
We must also note that if this black hole really exists, it confounds the theories of cosmologists as to the formation of the universe. It is too soon after the Big Bang for such a black hole to have formed, according to those theories.
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 print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. 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
