Ylem meaning in hindi

/ˈiːlɛm/

in cosmology, the original matter that, according to the big bang theory, existed before the formation of the chemical elements

ब्रह्माण्ड विज्ञान में, मूल पदार्थ जो, बिग बैंग सिद्धांत के अनुसार, रासायनिक तत्वों के निर्माण से पहले अस्तित्व में था

The ylem existed before atoms formed from electrons, neutrons and protons.

इलेम इलेक्ट्रॉनों, न्यूट्रॉन और प्रोटॉन से बनने वाले परमाणुओं से पहले अस्तित्व में था।

1. In the Big Bang theory, the hot and dense plasma which made up the cosmos at the time of recombination in an early stage of its expansion and cooling, when the first atoms formed and photons decoupled. The ylem is regarded as the source of the cosmic microwave background.

बिग बैंग सिद्धांत में, गर्म और सघन प्लाज़्मा जिसने अपने विस्तार और शीतलन के प्रारंभिक चरण में पुनर्संयोजन के समय ब्रह्मांड को बनाया, जब पहले परमाणु बने और फोटॉन अलग हो गए। यलेम को ब्रह्मांडीय माइक्रोवेव पृष्ठभूमि का स्रोत माना जाता है।

1. He [George Gamow] surmised that that the universe began as a super-condensed raging inferno of protons, neutrons and electrons, which he and his colleagues called the ylem The internal pressures of the ylem caused it to expand outward extremely rapidly. After a few minutes the ylem cooled down sufficiently to allow the strong force to bind neutrons and protons together into deuterium nuclei. Then there was just enough time for some of the deuterium to fuse into helium before temperatures and pressures of the ylem became too diffuse to allow more fusions.

2. Let us now consider the state of matter during the first minutes of the expansion process, when the temperature of the universe was many billions of degrees high. [T]he state of matter must be visualized as a hot gas formed entirely by nuclear particles; that is, protons, neutrons, and electrons. We will call this primordial mixture of nuclear particles "Ylem," [footnote: Pronounced: ī′lěm] reviving an obsolete noun which, according to Webster's Dictionary, means "the first substance from which the elements were supposed to be formed." Next we can ask what happened to the Ylem when its density and temperature began to drop as the result of the rapid expansion taking place in the young universe.

3. The ylem was the primordial flux of neutrons out of which all else emerged.

4. Very shortly after the beginning of the universal expansion, the ylem was a gas of neutrons only. [Footnote: According to Webster's New International Dictionary, 2nd Ed., the word ‘ylem’ is an obsolete noun meaning ‘The primordial substance from which the elements were formed.’ It seems highly desirable that a word of so appropriate a meaning be resurrected.]
