Dark radiation

Okay kiddo, you know how we see light around us all the time? Well, there's something called dark radiation that scientists think exists, and it's kind of like light, but we can't see it because it's too faint.

Dark radiation is a type of energy that travels through space and it's believed to be made up of tiny particles called neutrinos that have no electric charge and hardly any mass. These particles come from the sun and stars and travel through space at huge speeds.

Now, these neutrinos are called "dark" because they are really hard to detect – scientists have to use fancy equipment to catch them! And just like we can't see the wind, we can't see the dark radiation.

Scientists believe that this dark radiation can tell us more about the universe and its origins. It's like a little puzzle piece that helps us understand how everything started. But, since it's so hard to detect, scientists are still trying to learn more about it, and there's a lot we still don't know.

So, to sum it up, dark radiation is a type of energy that travels through space made up of tiny particles called neutrinos. We can't see it because it's too faint, but scientists think it can help us understand the universe more.
