The Big Bang

 

The Big Bang

The maximum age of the observable Universe, established by measuring the anisotropy of the cosmic microwave background, is 13.801±0.024 billion years. (2020AghanimN_RoudierG). The relic stages of the creation of the World are only approximately understood by theoretical physicists. The development of matter into molecules, as well as the start of time, is logically described by the Big Bang theory and the concept of the expansion of space (2012HawkingS). It is impossible to imagine the Universe before its expansion from some homogeneous space or an infinitesimal grain. The reason for this is the «inner cosmic oblivion» of the previous state (2007BojowaldM). In our opinion, before that there was a black, cold, motionless Peace. Accordingly, before the mark of 13.8 billion years ago, the search for evidence of ligamentum capitis femoris (LCF) is futile anywhere in the Universe.

One second after the Big Bang, the Universe consisted of light and elementary particles heated to 10 billion degrees Celsius. About 380 thousand years later, atomic nuclei began to capture electrons. Over the next 200 million years, the Universe consisted of hydrogen, helium, and trace amounts of other chemical elements. Then the first stars lit up, gathering into the first galaxies over several hundred million years (science.nasa.gov).

The oldest known galaxy, JADES-GS-z14-0, has a redshift of 14.32, meaning it arose no later than 300 million years after the Big Bang (CarnianiS_WillmerCN). Bright emission lines of hydrogen and oxygen have been observed in the spectrum of JADES-GS-z14-0 (blogs.nasa.gov). In the galaxies that arose around 300 million years later, stars have an approximate age of 30–50 million years (RobertsonB_WitstokJ). Carbon synthesis and its ratio to oxygen similar to and higher than the solar one is noted in the galaxy GS-z12, formed approximately 350 million years after the Big Bang (D’EugenioF_WillottC). Carbon grains have been discovered in the galaxy JADES-GS-z6-0, which is approximately 800 million years old after the Big Bang (WitstokJ_WillmerCN).

Therefore, in JADES-GS-z6-0 there are chemical prerequisites for the emergence of the known form of carbon-based life and creatures capable of locomotion. We cannot exclude that on one of the planets of this galaxy the first LCF in the Universe arose. If the evolution of living beings proceeded at the Earth's speed (see Tiktaalik roseae), then the oldest LCF could have formed 4.975-4.935 billion years after the Big Bang or 8.865-8.825 billion years ago.

It should be noted that in this case we are talking about LCF from ordinary matter available for us to study. It accounts for 4.9% of the mass/energy density of the Universe. At the same time, dark matter, detected by indirect signs (gravitational influence), makes up 26.8% (cam.ac.uk). The presented data suggest that LCF from dark matter may exist in parallel, including on Earth.

The Solar System

  The Solar System As a result of a mysterious catastrophic event about 13.8 billion years ago, the Universe was formed (2012HawkingS; 2020AghanimN_RoudierG). In it, giant cloud-like accumulations of plasma, molecules and dust became the points of star formation (2011MurrayN). A series of their generations, igniting, functioning and collapsing, led to the appearance of various chemical elements through staged reactions of nuclear fusion (1998IshkhanovBS_TutynIA). The Sun was born for at least ten million years by compressing a concentration of molecular gas and parts of the most ancient stars (2010HanslmeierA). As a result, 4.5682-4.567 billion years ago, the Solar System self-organized, at the dawn of its life consisting of a central luminary and a protoplanetary gas and dust disk (2013HazenRM). At least the oldest meteorite inclusions were fused 4.568-4.565 billion years ago, and at most three million years later, accretion of chondrite globules occurred (1995AllègreCJ_GöpelC). T...

344-411Rufinus Aquileiensis

  A fragment of the manuscript of the translation of Josephus Flavius' Antiquities of the Jews ( Ἰουδαϊκὴ ἀρχαιολογία / De antiquitate iudaica) into Latin by Rufinus Aquileiensis. The translator worked approximately between 344 and 411 in the Roman Empire. His work was rewritten between 1150 and 1199 in Northern France. In Josephus's translation of Antiquities of the Jews, ligamentum capitis femoris (LCF) is referred to as «neruum». The selected fragment deals with the LCF of an animal and discusses a biblical episode of its damage in a human. See our commentary at the link: 344-411Rufinus Aquileiensis [Rus].
