The study traces dark matter using hydrogen in the Lyman-Alpha forest, revealing tensions between observed cosmic data and theoretical expectations, hinting at new particles or effects from black holes. The sharp peaks observed in the wavelength distribution graph of a Lyman-Alpha forest indeed resemble a series of miniature trees. Each of those peaks represents a ..read more

A University of Chicago-led analysis measuring the universe expansion rate, finds there may not be a ‘Hubble tension’. The “crisis in cosmology,” sparked by differing measurements of the universe’s expansion, may be nearing a resolution thanks to the James Webb Space Telescope. New data analyzed by scientists suggests that the Hubble tension might not be ..read more
