10 Possible Future Disasters That Could Wipe Out Humanity from the Face of the Planet
The world has always been under constant threat even from the early days of evolution. From asteroids and comets to dangers from within, there are several possibilities of horrible future events to wipe out humanity. Here are ten such scenarios which can become very real.
1 Gamma Ray Burst
The star Wolf-Rayet star WR 104 is just 8,000 light years from the Sun. It possesses the capacity to explode in a hyper nova that can produce gamma rays aimed at the Earth in the next 10,000 years. The gamma rays would produce intense UV radiation and possibly cause a global catastrophe by depleting the ozone layer and causing nitric acid rain. Scientifically speaking the Wolf Rayet star is expected to explode and hit the earth with Gamma rays in 500,000 years.
2 Collision with rogue planet
The moon was formed a 100 million years ago as the result of a collision with a rogue planet named Theia. A collision of this level would mean the end of humanity. The presence of material from Theia was found in the composition of moon rocks brought back by the Apollo missions. This means there is no ruling out a second collision of this sort.
3 Alien invasion
The official line is that no Extraterrestrial life has been observed as yet. A NASA affiliated scientist Shawn Domogal Goldman has compiled the possible outcomes of alien contact. They would either be friendly or help us advance our knowledge or they could be hostile, attack earth or carry dangerous pathogens that could wipe out the human race.
