Why Haven’t We Seen a Supernova Since 1604? The Milky Way Mystery #supernova #milkyway #neutrino

[00:00:00]Since the year604, we haven't seen a single supernova in our galaxy. Wait, think about that. Current theories say that there should be one supernova every 50 years. That means we've missed at least eight supernovas by now. So, the question isn't whether these explosions are happening. The question is why can't we see them? What if it's the Milky Way itself that's deceiving us? Because right at its center lies a visual cosmic dust cloud that absorbs light. That means a star could be exploding, but its light never reaches us. But here's an even bigger question. Can this dust cloud also block the nutrinos coming from a supernova? No. Nutrinos pass through almost everything. Then why haven't we detected them? Because our detectors still aren't sensitive enough to reliably catch nutrino signals coming from every corner of the galaxy. And a supernova is a rare event. Unless it happens relatively close to us, the signal becomes extremely weak. But that's about to change because the next time a star explodes, we won't just see it. We'll detect it before it becomes visible. When a star is about to die, it doesn't show light first. First come gravitational waves. Then come nutrinos.

[00:01:12]And only after that comes the light we recognize as a supernova. Which means the next time a star explodes, we'll feel it before we see it. And the moment those signals arrive, the world's most advanced telescopes will turn toward that exact direction and capture the very moment a star begins to explode.

[00:01:30]And if this happens in our Milky Way, for the first time, we'll witness a star die from beginning to end. Supernovas have always been happening. The difference is this time, we won't miss them. Subscribe now because the next supernova might happen any moment and you don't want to miss
