Unveiling the Early Universe: Moon-based Radio Telescopes Provide New Insights

Tel Aviv University researchers have published a study in Nature Astronomy, proposing that radio telescopes on the moon could provide groundbreaking insights into the early universe, specifically the cosmic dark ages just 50 million years after the Big Bang. By detecting radio waves emitted from hydrogen gas during that time, scientists could test the standard cosmological model, determine the composition of the universe, and potentially gain clues about dark matter. The study also suggests that a lunar antenna array could accurately measure the amount of hydrogen and helium in the universe, as well as the weight of cosmic neutrinos.
