Human curiosity and hunger for power has helped the humanity conquer many realms of previously unexplored territories but what if one major step taken in attempt to benefit the mankind might have gone wrong and led to the ultimate demise of mankind. Many such experiments have been held in the past, we bring you some.

5.The Kola Superdeep Borehole

Located in the Arctic Circle within the far Northwest corner of Russia is the deepest hole ever drilled into the Earth’s crust. Soviet scientists began drilling in the 1970, eventually reaching a depth of 40,230 ft (12,626 m) in 1989. The Soviets wanted to drill through the Earth’s crust and then into the upper mantle but had to stop when the rocks at 1737 Celsius began flowing into the borehole, speculations were that the drilling might cause disastrous seismic activities and open the doors of hell. (these theists I tell you)

4.The Trinity Test

Conducted as a part of the Manhattan project, this was one of the first atomic bombs to be tested which came with certain complications and fears. One of them being that the fission reaction might trigger a self-sustaining fusion reaction of the Nitrogen nuclei but the bomb was detonated anyhow releasing the power equivalent of 21 kilotons of TNT.
