I think you're right, Bingley. It's the tricky sentence for me. Could wsieber assist?

<<Seiner Vorhersage zufolge können ab und zu Partikel den Ereignishorizont des Schwarzen Lochs überwinden und entkommen als Strahlung>>

"According to their prediction, a particle could occassionally escape [lit. "defeat"] the "phenomenal horizon" of the black hole and escape as radiation."

Thanks, Bing.
