Just Six Numbers: The Constants that Rule the Universe

This book talks about six numbers, which now seem to be of particular and significant importance; two of these numbers relate to the "fundamental forces", two more (the size of our universe) and (the totality of it) determine whether it will last forever or not, and then the remaining two (the properties of space) determine itself: The universe is so vast because there is one huge number that is so important in nature, symbolized by (N), which is equal to: 1.000.000.000.000.000.000.000.000.000.000.000.000 This number measures the strength (electrical forces), which bind atoms together divided by the forces of attraction between atoms. If N zeros were reduced to a few zeros, there could be only a tiny, short-lived universe, and an organism would not have grown to a larger size than an insect. Another number, 0.007, determines how strong the nuclei are, and how all the atoms on Earth are made. Its value controls the power coming out of the sun, and more importantly, it controls how stars convert hydrogen to the rest of the periodic table. Carbon and oxygen are diffused, while gold and uranium are scarce, because of what goes on in the stars. * The cosmological number (or omega) measures the amount of matter in our universe, from scattered galaxies and gases and dark matter. (ii) tells us the relative importance of gravity and expansion energy in the universe. If this ratio were higher than its (critical) value, the planet would have collapsed long ago, and if it were lower, no galaxies or stars would have formed. The fourth number, or Lmda, was the biggest scientific news in 1998, where an unexpected new force, anti-gravity, is controlling the expansion of our universe, although it does not have a clear impact on a scale less than a billion light years. This force is destined to prevail over gravity and other forces as our universe becomes darker and empty. The seeds of all the cosmic structures – stars, galaxies, clusters of galaxies – were placed in the Big Bang, and the fabric of our universe depends on a single number (Q), which represents (the ratio between two fundamental energies), and its value is about 1/100,000. If (Q) were slightly smaller, the universe would be inactive and devoid of any structures, and if (Q) was much larger, the universe would be a stormy, sunless place. The sixth number, also important, has been known for centuries, but now it's called Superstrings; it's a number (the dimensions of space) in our world (D), and it's equal to 3. Life wouldn't exist if (D) were equal to 2 or 4. Time is four, but it's different from the rest of the dimensions in that it's an arrow pointing, we're just moving forward, towards the future. I have highlighted these six numbers because each of them plays an important and distinctive role in our universe, and together they determine how the universe evolves, and what inner potentials and forces lie within it. - Dr. Martin Rees (British astronomer) More: https://braheen.com/publications/فقط-ستة-أرقام-القوى-العظمى-التي-تشكل-الكون — Source: Published on Facebook's "Braheen Center" page
