The temperature changes of the first light of the early universe were translated into a stream of bits and analyzed by a German astrophysicist.
The hypothesis about the existence of a potential message from a possible creator of the universe (if there was one) that would be visible to all technological civilizations was first put forward in 2006 in an article by theoretical physicists Stephen Hsu (University of Oregon) and Anthony Zee (University of California).
More than a decade later, Michael Hippke, who identifies as an independent scientist researching astrophysics in his “spare time” and is affiliated with the Sonneberg Observatory (Germany), decided to try and find that message in the spectrum. of angular power of the background Cosmic microwave (CMB).
What is the CMB?
The CMB shows the early universe and dates back to around 380,000 years after the Big Bang. Before the time of recombination, the cosmos was completely dark and opaque, and so hot and dense that atoms could not be formed while protons and electrons flew in the form of ionized plasma.
As the universe cooled and expanded, these particles began to combine to form neutral hydrogen atoms. The space cleared and for the first time the light was able to pass through it freely. This first light – which is still detectable today and covers all known space – is the CMB.
How was the “message of the creator” searched?
Since the early universe was not uniform, the changes in density at the time of recombination now manifest themselves in very slight fluctuations in the temperature of the CMB.
Hippke translated these CMB temperature changes into a stream of bits (binary sequence), as Hsu and Zee hypothesized that the CMB was “the largest billboard in the sky, visible to all technological civilizations”, where a message that ” would be identical for all observers in space and time and the content of the information could be reasonably large (thousands of bits) “.
However, Hippke found out there are several problems with these statements. The first is that the CMB is still cooling down. Its initial temperature was around 3,000 Kelvin and is currently 2.7 Kelvin. As the Universe continues to age, eventually the CMB will become undetectable and disappear, this can happen within 10 two million years.
Also, according to Hippke, it is extremely unlikely the CMB will look exactly the same in the sky for different observers in different places. Also, we cannot see the entire CMB due to the Milky Way’s foreground emission.
Stream of 1,000 bits
Based on these limitations, Hippke estimates that the content of the potential “message from the creator” would be much less than the thousands of bits assumed by Hsu and Zee: just 1,000 bits. Starting from this, the astrophysicist analyzed the temperature fluctuations in the CMB, recorded by the Planck satellite and the Wilkinson microwave anisotropy probe (WMAP). From these datasets he extracted his bit stream, compared the results of each group to find matching bits, but could not find “any significant message in the actual bit stream”.
“We can conclude that there is no obvious message from the sky in the CMB. However, it’s unclear if there is (was) a creator, if we lived in a simulation or if the message printed correctly in the previous section, but we couldn’t figure it out, “he summarized. Hippke included said bitstream real for the purpose of his study “for the interested reader to examine.” Hippke’s article was published on the arXiv online repository and not yet peer reviewed.
