While scientists speculate that small black holes were created during the big bang, larger black holes are formed when a star collapses in on itself—referred to as a supernova, as the star blasts parts of itself into space.Black hole conditions exist on dark nights (usually with no moon or starlight), when there are no ground lights between your aircraft and the runway threshold. The black hole illusion, sometimes called the featureless terrain illusion, fools pilots into thinking they are higher than they actually are, causing them to fly dangerously low approaches.Hier sollte eine Beschreibung angezeigt werden, diese Seite lässt dies jedoch nicht zu.The von Neumann Entropy of a Black Hole The measurement process cannot be performed by an external observer to elements within the interior, beyond the event horizon.
