How did the world end?
who knows how the world would end but the hollywood brother knows that the tickling would go on with whoever takes over the world
However, a few billion years before either event will see the sun's gradual heating become so intense, that the oceans themselves will boil off...
It's already beginning to end here in my town...floods, major power outages..horrible heat indexes...o no..it's the end of the world as we know it..

In approximately 4.5 billion years, the Andromeda Galaxy will collide/merge with ours. There's a high degree of uncertainty concerning how that will affect the Earth, but there's a 50/50 chance of it doing something.
In approximately 5.5 billion years, the sun will expand into a red giant as it runs out of Hydrogen to fuse. The sun's outer atmosphere will be larger than the obit of the Earth, but it will also have lower gravity. The Earth will either then plunge into the sun and burn away, or hurtle off into interstellar space where it will freeze.
However, a few billion years before either event will see the sun's gradual heating become so intense, that the oceans themselves will boil off. This might even cause a runaway greenhouse effect similar to Venus, where the surface temperature is around 900 degrees fahrenheit, and the atmospheric pressure 90x that of Earth.
There's always the off chance of being struck by asteroid, too. One needs a healthy respect for large city-sized objects traveling at cometary speeds. They would yield explosions several times greater than the nuclear weapons detonated over Japan in 1945.
The world may end, but humanity doesn't have to. Keep that in mind.

To Mars!!!
Only possible if we invent nanites (not only to terraform Mars but also to make it so we don't suffer from depressurization (Mar's is smaller than Earth and thus doesn't have the same level of pressure).
Uh, nope. It's a 3 year trip to Mars in even China's fastest shuttle dude.
