Yeah, I caught this also.....and oddly we're still here. Somebody miscalculated. That's what makes theoretical physics so, ummm, "theoretical."
And then this other one that came immediately after....NASA picking up powerful X-ray emissions from someplace, as I recall, some 300 or 350 million light years away.![]()
