There are reports of the end of the planet, after many researches and studies in Britain and the United States of America, France and Sweden recently.
The latest of these studies is the work of the famous British theoretical physicist Stephen Hawking, who predicted a new date for the end of the world, or what he called the "doomsday" for the planet.
Hawking said in November that life would end on the planet in a thousand years, but it was reduced to a possible 100-year period.
Hawking's predictions came during a scientific program called "New Earth Mission", which was later broadcast by the BBC as part of the "Tomorrow's Science World" program season.
The famous physicist in his scientific theories relies on an intelligent computer of physical theories.
Hawking suggests a single way out of this impasse, and to preserve the life of humanity, which is to search for the next 100 years from extraterrestrial life.
"With climate change, the expected Earth strikes from space asteroids and the spread of epidemics, our planet is becoming increasingly unstable," the BBC quoted Hawking as saying.
The Hawking report urged engineering expert Daniel George and his former student Christoph Gallafard to look at how humans reach stars and move to planets other than the planet.
Hawking is suffering from a neurodegenerative disease that has caused him to be incapacitated, before the disease developed to become speechless. He then had to use a sound computer to talk and communicate with others.
Over the past months, Hawking began to speak clearly about the need for mankind to search for planet B as an alternative to life on Earth, while in the past he called for the colonization of the moon or Mars as an appropriate solution to sustain human life.
