And although the expected radio signals will be weak, their observation would open up brand new areas for testing theories for dark matter. And once the very early stars started linking into existence, that's cosmic dawn, the light they produced probably amplified these radio transmissions dramatically. And as of now, the only real way to detect dark matter is indirectly, which makes it really hard to isolate. But during the early universe, the setting was pristine and a perfect way to investigate how dark matter became. So the earlier, the farther, farther back we go, you're getting glimpses of the early universe and it's being more and more pristine without a lot of interference. So that's the best place to be looking for some of these signals.
