Source: en.wiktionary.orgHistory is a set of nested resonances with each epoch being shorter than the one that preceded it. This event horizon is like a series of ghost horizons, and once you enter into history, you enter into the outer shell of the temporal field of the attractor or the concrescence. Terence McKenna
My to-do list is so long that it doesn't have an end; it has an event horizon. Craig Bruce
According to their own clocks, which appear to them to tick normally, they cross the event horizon after a finite time without noting any singular behaviour; it is impossible to determine the location of the event horizon from local observations. Source: Internet
A RUDN University physicist has developed a formula for calculating Hawking radiation on the event horizon of a black hole, which allows physicists to determine how this radiation would be changed with quantum corrections to Einstein's theory of gravity. Source: Internet
D Modern observations of accelerating expansion imply that more and more of the currently visible universe will pass beyond our event horizon and out of contact with us. Source: Internet
But Catarina has the denseness of a black hole, and everyone is pulled into her event horizon. Source: Internet
