The cosmology PhD
Zeeya Merali authored a recent book entitled A Big Bang in a
Little Room: The Quest to Create New Universes. When I look up
this book on www.amazon.com, I
see the following claim in the text promoting the book: “As
startling as it sounds, modern physics suggests that within the next
two decades, scientists may be able to perform this seemingly divine
feat – to concoct an entirely new baby universe, complete with its
own physical laws, star systems, galaxies, and even intelligent
life.” The claim is complete nonsense, and there is nothing at all
in the book that justifies such a laughable claim. What the book
actually discusses rather briefly are a few cases where a theorist
has speculated that if his theory is true, then you might be able to
create some fleeting microscopic irregularity; and the theorist calls
such irregularities “universes.” The theories in question are
just speculative schemes which are completely unproven.
Merali's book is
fairly interesting and has some interviews with prominent
cosmologists. Having lots of material for a good book, we can only
wonder why she chose a book title hyping this “manufacturing of
baby universes” nonsense. Maybe, it was kind of a “that will
attract attention” type of thing. As the Big Bang involves an
entire universe, the very phrase “a Big Bang in a little room”
makes no more sense than a “big galaxy in a little soda bottle.”
One of the
interviews in the book is with a cosmologist named Anthony Zee who
suggested an interesting idea: that a Creator of the universe might
cause a message to exist in the cosmic background radiation. The
cosmic background radiation pervades all of space, and is believed to
be the afterglow of the Big Bang in which the universe began. In a
scientific paper entitled “Message in the Sky,” Zee and co-author
S. Hsu speculate that if a Creator of the universe wanted to provide
a message, the cosmic background radiation would provide a
“stupendous opportunity,” since the same message could be
observed all over the visible universe. It is believed that the
cosmic background radiation looks the same to observers all over the
universe.
Zee
and Hsu do not provide any evidence that the cosmic background
radiation actually has such a message. They merely speculate about
low-level details of how such a message could be implanted in the
cosmic background radiation, suggesting that such a message could be
found “hidden
in very small temperature fluctuations in the CMB (of order 10−5)
,presumably resulting from primordial density perturbations.”
Another
interesting idea is that a Creator of the universe might put a
message or signal in pi, the ratio between the diameter and the
circumference of a circle. Some scientists wrote a scientific paper
entitled “Pi in the Sky” which addressed this possibility. The
paper begins by suggesting that there is statistical nonrandomness in
both pi and the cosmic background radiation. We hear a discussion of
various such abnormalities, and it sounds fascinating.
But
then the paper tells us that if we convert the digits of pi into
letters, we get a message. There's a visual suggesting that when the
first digits of pi are converted into letters, we read the full name
of Stephen Hawking: Stephen William Hawking. At this point the paper
gives away that it's a fake. The paper has a date of April 1, 2016.
I think poorly of people who put up fake material on the Internet, and I do not
excuse them for using April Fool's Day as an excuse.
The
idea that a divine creator might use pi as a kind of divine
calling card was once suggested by an unlikely source: the late
astronomer Carl Sagan. In his nonfiction writings Sagan had always
sounded completely irreligious. So it must have come as a surprise to
readers of Sagan's novel Contact
when they read the book's end. In the novel's end, scientists
discovered that there was a gigantic circle pattern embedded in the
digits of pi, something that the novel said was proof that the
universe had been designed. This highly original ending was removed
from the movie version of Contact
starring Jodie Foster, which left in an unoriginal “meet an
extraterrestrial looking just like a human” element that reminded people
of previous scenes in The
Twilight Zone
and The
Day the Earth Stood Still.
Sagan's
idea of a message embedded in the digits of pi raises the interesting
philosophy of mathematics question as to whether such a thing could
conceivably be done by an omnipotent agent. Are the digits of pi some
transcendental thing that must be the same in every possible
universe? Or could an omnipotent agent create a universe that had pi
digits with some desired sequence?
Another
idea along these lines is the possibility that some transcendent
force might leave a calling card in the genetic code, the system of
symbolic representations used by all earthly life. Something along
these lines has been suggested in the scientific paper “The 'Wow!
Signal' of the Terrestrial Genetic Code” by two scientists. The
scientists claim to have found “readily
recognizable hallmarks of artificiality” in the genetic code, and
claim that this may indicate that earthly life was brought here by
extraterrestrials.
I
can think of one other possibility along these lines, a scenario that
we might call “a calling card left in the subatomic particles.”
Imagine you are creating a universe. You could create the universe so
that all matter was built from two or three stable subatomic
particles, including a positively charged particle and a negatively
charged particle. Each of the positively charged particles might be
hundreds or thousands of times more massive than each of the
negatively charged particles. But when you set up this universe you
could make it so that the charge of each of the negatively charged
particles was the exact opposite of the charge on each of the
positively charged particles. Across the universe you had created,
scientists would be able to discover this coincidence. After the
scientists across your universe had measured that the charge on the
negatively charged particle was the exact opposite of the charge on
the positively charged particle, with the match extending to twenty
decimal places, would they then not conclude that this was some
“signal in the particles” that indicated you had set things up
very precisely?
No,
they would do no such thing; the scientists would simply ignore
the exact match. We know this from the example of our universe. For
there exists exactly such a match in our universe, in which each
proton has a mass 1836 times greater than each electron, but in
which the charge of the electron is the exact opposite of the charge
of the proton, with the match being to twenty decimal places.
Our sharp-eyed scientists have paid no attention to this exact match.
