G'day Ginger,
Thanks for the question.
We have a general idea of what might cause the end of the world. However, what the world will be like just before it ends is impossible to predict.
It is certain that events in space will cause life on Earth to come to an end. The certain events, however, will happen at an extremely long timescale measured in billions of years. Projections indicate that the Andromeda Galaxy is on a collision course with the Milky Way. Impact is predicted in about 3 billion years, and so Andromeda will approach at an average speed of about 140 kilometres (87 miles) per second; the two galaxies will probably merge to form a giant elliptical. This merging will most likely eject the solar system in a more eccentric orbit and an unwanted position in the merged galaxy causing our planet to become uninhabitable (an actual collision is unnecessary). In 6 to 7 billion years, stellar evolution predicts our sun will evolve into a red giant and will probably completely envelop the Earth. Because of a new process in the sun's core (fusion of helium besides a fusion of hydrogen) and radiation pressure, the sun's diameter will expand to nearly Venus orbit. Besides the red giant option, there are some astronomers who believe that the sun is currently increasing in luminosity (at a very slow rate), and they predict that in fewer than one billion years, the Earth will be too hot for life as we know it to survive, and have too much radiation as well.
On an even longer time scale, the universe will come to an end. The current age of the universe is estimated as being 13.7 billion years. There are several competing theories as to the nature of our universe and how it will end, but in all cases, there will be no life possible. These scenarios take place on a considerably longer timescale than the expanding of the sun.
I have attached additional sources for your reference.

When the world ends, maybe the stars hit each other, the Sun hit the Earth and no stars or planet can be intact. Dark covers everything.

Unless man destroys it first, it will eventually be burned up as the sun goes from its current yellow phase into its red giant phase. But, this isn't going to happen for 4 billions years or so, so don't lose too much sleep over it.
