There are very few situations the world could end up in that can actually be considered world-ending or even world-changing. Many of such events are categorized as such by media to get more attention.

The "world" is coming to a close though. Maybe by my hundredth birthday, the world'll be changed either horrifically or for the better. However, contrary to the Mayans, bless their well-meaning hearts, I do not believe the Earth itself will ever be destroyed either on the surface or as a whole. I also do not believe in supernovas or black hole anomalies. These are mostly theories and unexplained phenomena which we can't truly figure without the help of warpdrive for our space travel. Looking through a telescope no matter how powerful is not proof that black holes exist or that supernovas occur. You might as well continue to believe that the Earth is a flat plane and that the universe is only 50000km in diameter.

Error! Closer to about 6000 years so far. Dinosaurs died out during Noah's flood. They didn't live millions of years. But the day will arrive when billion-year life is possible.
