"Revolutionary Telescope Unveils Secrets of Decaying Dark Matter in Early Universe"

The Hydrogen Epoch of Reionization Array (HERA), a radio telescope in South Africa, could potentially detect decaying dark matter particles in the early Universe. By observing the 21-centimeter line emitted by neutral hydrogen, HERA may provide evidence of dark matter decay, which would interact with the emitted light. Even if no evidence is found, HERA's observations would still help constrain the half-life of dark matter and narrow down the range of possible models.
