1. Asteroid Explosion
The reason for the demise of the dinosaurs was linked to the impact of a 10km asteroid in Mexico about 6500000 years ago. In 1908, an asteroid of about 110m across exploded 6km above the Earth, releasing energy equivalent to a thousand Hiroshima’s over Siberia.

2. Robotic invasion
Robots are being used all over the world in military operations, carrying military weapons and can easily identify human targets on their own.

3. Super volcano
Tambora erupted in 1815 with a high rating on the Volcanic Explosivity Index, making it the largest of the eruptions ever since the Lake Taupo eruption in 180 CE. The death toll was more than seventy thousand people.

4. Alien Invasion
Taken to account that there are roughly 1011 galaxies, every galaxy having 1011 stars and every star having its own solar system, the probability of life on other planets is a likely one.

5. Global warming
Global warming has been a topic of concern for a very long time. But we are least bothered as it would take 60 to 100 years before we will actually have to deal with its effects.

6. Invasion of grey goo
Grey goo is a kind of nano device which takes in biomass and turns it into copies of its grey goo device. If such a device were not controlled, it could eat the whole biosphere.

7. Nuclear Holocaust
World War 3 would mean the end of human civilization as there is a wide possibility of usage of nuclear weapons.

It will come from our own hands, only a matter of time before it get's started. The worst enemy is one that has no fear of death or that might actually want to die for his beliefs or religion. We have already experienced that and the worst is yet to come so be prepared, the internet will one day cease to exist. Now about the possibility of other life out there, absolutely, live organisms have already been discovered riding on meteors, one such organism was able to withstand extreme high heat and would actually roll into a ball to protect it's limbs, when the temperature cools the limbs once again extend. Just mind boggling.

How about the end of everything?

1) Big Freeze or heat death

The Big Freeze is a scenario under which continued expansion results in a universe that asymptotically approaches absolute zero temperature. It could, in the absence of dark energy, occur only under a flat or hyperbolic geometry. With a positive cosmological constant, it could also occur in a closed universe. In this scenario, stars are expected to form normally for 1012 to 1014 (1-100 trillion) years, but eventually the supply of gas needed for star formation will be exhausted. As existing stars run out of fuel and cease to shine, the universe will slowly and inexorably grow darker. Eventually black holes will dominate the universe, which themselves will disappear over time as they emit Hawking radiation. A related scenario is heat death, which states that the universe goes to a state of maximum entropy in which everything is evenly distributed, and there are no gradients — which are needed to sustain information processing, one form of which is life. The heat death scenario is compatible with any of the three spatial models, but requires that the universe reach an eventual temperature minimum.

2) Big Rip

In the special case of phantom dark energy, which has even more negative pressure than a simple cosmological constant, the density of dark energy increases with time, causing the rate of acceleration to increase, leading to a steady increase in the Hubble constant. As a result, all material objects in the universe, starting with galaxies and eventually (in a finite time) all forms, no matter how small, will disintegrate into unbound elementary particles and radiation, ripped apart by the phantom energy force and shooting apart from each other. The end state of the universe is a singularity, as the dark energy density and expansion rate becomes infinite.

3)Big Crunch

The Big Crunch hypothesis is a symmetric view of the ultimate fate of the Universe. Just as the Big Bang started a cosmological expansion, this theory assumes that the average density of the universe is enough to stop its expansion and begin contracting. The end result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity, but at these scales unknown quantum effects need to be considered (see Quantum gravity).

This scenario allows the Big Bang to be immediately after the Big Crunch of a preceding universe. If this occurs repeatedly, we have a cyclic model which is also known as an oscillatory universe. The universe could then consist of an infinite sequence of finite universes, each finite universe ending with a Big Crunch that is also the Big Bang of the next universe. Theoretically, the cyclic universe could not be reconciled with the second law of thermodynamics: entropy would build up from oscillation to oscillation and cause heat death. Current evidence also indicates the universe is not closed. This has caused cosmologists to abandon the oscillating universe model. A somewhat similar idea is embraced by the cyclic model, but this idea evades heat death, because of an expansion of the branes that dilutes entropy accumulated in the previous cycle

4)Big Bounce

The Big Bounce is a theorized scientific model related to the beginning of the known universe. It derives from the oscillatory universe or cyclic repetition interpretation of the Big Bang where the first cosmological event was the result of the collapse of a previous universe.

According to one version of the Big Bang theory of cosmology, in the beginning the universe had infinite density. Such a description seems to be at odds with everything else in physics, and especially quantum mechanics and its uncertainty principle.[citation needed] It is not surprising, therefore, that quantum mechanics has given rise to an alternative version of the Big Bang theory. Also, if the universe is closed, this theory would predict that once this universe collapses it will spawn another universe in an event similar to the Big Bang after a universal singularity is reached or a repulsive quantum force causes re-expansion.

In simple terms, this theory states that the universe will continuously repeat the cycle of a Big Bang, followed up with a Big Crunch.

How can a scientist know there is billions of years left in the sun? Science has been wrong on many incidents and tomorrow the gas may run out.

The earth is spinning a lot slower now. Scientist tells us there are millions billions years left until the earth stops spinning, but....people do drop dead even though they have heck of a lot of years left in them...just saying.

There's nothing remotely interesting or cool about me.
How cool and interesting was that?!

If you don't want to see the end, just give the money to me :D
