We know that something with a big mass will collapse and will become a blackhole. We know also that an "easy" blackhole is the Schwarzschild solution of the Einstein's equations. An object free falling into a blackholes will pass the event orizont without problems but for an external observer he will never arrive to the event orizont. So for external observers blackholes won't increase its mass! Is it possible? Where do I make a mistake? Will the Schwarzschild radius never increase? Bye random3f P.S. I'm sorry for my English, I hope you can understand what I meant.
