Exploring the Universe Before the First Stars, Professor Barkana explains NASA's new James Webb Space Telescope discovered recently distant galaxies whose light we received from early galaxies around 300 billion years after the Big Bang. Our new research study has been an earlier and more mysterious era. The galaxy was formed in 400 million years after the Big Bang. Computer simulations predict that dark matter throughout the universe was forming dense clumps which would later help form the first stars and galaxies. The predicted size of these nuggets depends on and thus can help illuminate the unknown properties of dark matter. But, the hydrogen gas and caused it to emit stronger radio waves. We predict that the cumulative effect of all this can be detected with radio antennas that measure the average radio intensity on the sky. Space simulations suggest that radio signals from the dark ages while faint carry valuable clues about the invincibility that seeded the formation of galaxies. Detecting them could transform our understanding of the universe's earliest moments.
