  • A discovery challenging basic assumptions about cosmology

    The discovery of a second ultra-large structure in the distant universe has challenged some of the basic assumptions about cosmology. The Great Ring is 9.2 billion light-years from Earth. Its diameter is about 1.3 billion light-years and its circumference is about four billion light-years. Remarkably, the Great Ring and the Giant Arc, which is 3.3 billion light-years in diameter, are in the same cosmological neighborhood.

     

     

    An exoplanet potentially habitable ?

    An exoplanet called LHS-1140b, located 50 light-years from Earth, is about 1.73 times larger and 5.6 times more massive than Earth. Due to a gravitational lock with its host star, a red dwarf cooler thanour Sun, one side of the planet always remains oriented toward the star, creating a potentially habitable zone where temperatures can reach 20 degrees Celsius.

     

     

    Challenging our understanding of dark energy

    Astronomers have discovered that one celestial hemisphere hosts just over half of all quasars, suggesting that one area of the night sky is more massive than the other. This challenges our understanding of dark energy, a hypothetical form of energy used to explain why the universe is expanding at an accelerating rate.

    (78aH*) : August 6th is the anniversary of the atomic bomb explosion on Hiroshima in 1945.
    This date represents the entrance of Humanity into the age of Revelation (Apocalypsis).
    Thus, since August 6, 2023, we are in 78 aH, (meanning 78 after Hiroshima).
    It is also an “atheist” and universal calendar to replace the existing “monotheist”, religious and non universal calendars.
