Personally, I believe in the final prophecy in Revelation. Most of the metaphorical language used in it I have translated into more realistic events though, including the worst earthquakes ever recorded, meteorites smashing to earth, etc.
http://en.wikipedia.org/wiki/Timeline_of_the_far_futureThis link gives me chills that I can feel from my legs into my cranial cavity. Listed some choice events. It's quite interesting to see what long-range scientists' predictions are.
100,000 Earth will likely have undergone a supervolcanic eruption large enough to erupt 400 km3 of magma.
Oh crud.
500,000 Earth will have likely been hit by a meteorite of roughly 1 km in diameter, assuming it cannot be averted.
Uh...let's hope not.
1 million Earth will likely have undergone a supervolcanic eruption large enough to erupt 3,200 km3 of magma; an event comparable to the Toba supereruption 75,000 years ago.
CRINGED!!
1 million Highest estimated time until the red supergiant star Betelgeuse explodes in a supernova. The explosion is expected to be easily visible in daylight.
The end of Nigeria This would be really cool.
50 million The Californian coast begins to be subducted into the Aleutian Trench due to its northward movement along the San Andreas Fault.[21]
Africa's collision with Eurasia closes the Mediterranean Basin and creates a mountain range similar to the Himalayas.
Wot
100 million Earth will have likely been hit by a meteorite comparable in size to the one that triggered the K–Pg extinction 65 million years ago.
Oh....first possibility of human extinction.
600 million The Sun's increasing luminosity begins to disrupt the carbonate–silicate cycle; higher luminosity increases weathering of surface rocks, which traps carbon dioxide in the ground as carbonate. As water evaporates from the Earth's surface, rocks harden, causing plate tectonics to slow and eventually stop. Without volcanoes to recycle carbon into the Earth's atmosphere, carbon dioxide levels begin to fall.[30] By this time, they will fall to the point at which C3 photosynthesis is no longer possible. All plants that utilize C3 photosynthesis (~99 percent of present-day species) will die.
RIP human race
1 billion[c] The Sun's luminosity has increased by 10 percent, causing Earth's surface temperatures to reach an average of ~320 K (47 °C, 116 °F). The atmosphere will become a "moist greenhouse", resulting in a runaway evaporation of the oceans.[33] Pockets of water may still be present at the poles, allowing abodes for simple life.
Yep, global warming

2.8 billion Earth's surface temperature, even at the poles, reaches an average of ~420 K (147 °C, 296 °F). At this point life, now reduced to unicellular colonies in isolated, scattered microenvironments such as high-altitude lakes or subsurface caves, will completely die out.
Life? What's that?
3.3 billion 1 percent chance that Mercury's orbit may become so elongated as to collide with Venus, sending the inner Solar System into chaos and potentially leading to a planetary collision with Earth.
We're all dead, so who cares?
3.5 billion Surface conditions on Earth are comparable to those on Venus today.
Cringe.
7.9 billion The Sun reaches the tip of the red-giant branch of the Hertzsprung–Russell diagram, achieving its maximum radius of 256 times the present day value.[50] In the process, Mercury, Venus and possibly Earth are destroyed.[51]
During these times, it is possible that Saturn's moon Titan could achieve surface temperatures necessary to support life.
RIP Earth
And yeah, I'm sure life will just form out of nothing on that moon?
3×1013 (30 trillion) Estimated time for the remnant Sun to undergo a close encounter with another star in the local Solar neighborhood. Whenever two stars (or stellar remnants) pass close to each other, their planets' orbits can be disrupted, potentially ejecting them from the system entirely. On average, the closer a planet's orbit to its parent star, the longer it takes to be ejected in this manner, because stars rarely pass so closely.
RIP what's left of the solar system
1015 (1 quadrillion) Estimated time until stellar close encounters detach all planets in Solar Systems from their orbits.[4]
By this point, the Sun will have cooled to five degrees above absolute zero.
RIP Sun
1010120 High estimate for the time for the Universe to reach its final energy state.
RIP universe, you were so kind.
