Olbers's paradox, also known as the dark night paradox or Olbers and Cheseaux's paradox, is an argument in astrophysics and physical cosmology that says that the darkness of the night sky conflicts with the assumption of an infinite and eternal static universe.
Jun 16, 2024 · But if true, isn't it a paradoxal situation such as Dark Matter exists and thus forms a halo around spiral galaxies not required, however, because the rotation curves are flat without it? What do you think about that?
If there’s dark matter present, it affects the radiation and normal matter due to gravity, but doesn’t interact the way normal matter does with itself or radiation.
Jan 18, 2024 · Olber's paradox asks a surprisingly easy yet profound question that has confused scientists and scholars for years. Why is the night sky dark? We found the answer in fundamental cosmology, a neat example of science giving answers to apparently mind-blowing questions.
Jun 28, 2023 · Have you ever pondered why space is black? This profound question lies at the heart of a centuries-old enigma known as Olber’s Paradox. Olber wondered, if the universe is infinite and full of stars, why we don’t see a uniformly bright night sky. Olber’s question led to investigations into the nature of the Universe that resolved his paradox.
Dark Matter and Dark Energy: These unseen forces influence the universe’s expansion and structure. While not directly related to the darkness of the sky, they’re crucial in explaining how galaxies move and grow, which affects the spread of light in the cosmos.
