  1. #SpeedOfLight Astrophysicists measuring in the farthest reaches of the cosmos are getting closer and closer to the initial moment of the Big Bang, to the flare that produced the radiation that permeates the entire universe, the cosmic microwave background (CMB). #physics

  2. #SpeedOfLight In more distant galaxies an expansion velocity is obtained that is significantly smaller than in closer galaxies. #physics

  3. #SpeedOfLight The Big Bang theory was controversial for several decades. Numerous attempts were made to accurately measure the rate at which the universe is expanding, the so-called Hubble constant. #physics

  4. #SpeedOfLight The spectacular concept of the expansion of the universe has given rise to new fields of study, such as experimental cosmology (data acquisition and observations) and the search for dark energy. #physics

  5. #SpeedOfLight Less than a century ago, very strong evidence was found that the expansion of the universe means that galaxies are moving away from each other, and at the same time the light they emit is increasing its wavelength (red shift). #physics

  6. #SpeedOfLight The expansion of the universe has important implications for the fate of the cosmos. If the expansion continues to accelerate, as current observations suggest, it may result in a future where galaxies drift apart, leading to the "Big Freeze" scenario. #physics

  7. #SpeedOfLight Observations of distant galaxies have revealed that the farther they are from us, the faster they move away. This fact is known as Hubble's law and provides strong evidence for the expansion of the universe. #physics

  8. #SpeedOfLight This expansion rate of the universe determines how quickly galaxies move away from each other and gives us information about the age and future of the universe. #physics

  9. #SpeedOfLight The expansion speed of the universe is described by the Hubble constant, named after astronomer Edwin Hubble, its discoverer. #physics

  10. #SpeedOfLight The expansion of the universe is not like the expansion of an object as we observe it in everyday life. It is the fabric that makes up the universe itself that is stretching, pulling galaxies with it. #physics

  11. #SpeedOfLight Exploding stars (called supernovae) formed the most massive elements and dispersed them into space. #physics

  12. 1/n Wednesday #NoeticSpectrum : It’s very hard to trace the current state of the #StandardModel back to any potential #TimeZero without recognition that you have to qualify that origin as a #Local time zero ; we parameterize all of of our inherent metrics in terms of the very finite
    #SpeedOfLight,which produces a horizon beyond which we should not be able to see.New data is challenging us beyond those limits. Many welcome that challenge.But the discomfort is too much for some and they run away-

  15. #SpeedOfLight Due to gravity, the clouds contracted these atoms to form stars, where hydrogen and helium fused to form, in successive steps, more massive chemical elements. #physics

  20. #SpeedOfLight When the temperature of the universe cooled to approximately 1 TK (Tera Kelvin), this soup fused into protons, neutrons, and electrons.

  21. #SpeedOfLight Albert Einstein's thoughtfulness and creativity revolutionized physics in the early 20th century.

  22. 🌌 Einstein’s Speed Limit Survives Its Toughest Test!
    Scientists measured light from a massive gamma-ray burst 7 billion light-years away, pushing the speed of light to its limits. The result? It remained constant, as predicted by Einstein over a century ago.
    Special relativity prevails.
