Nothing could be scary as hell when we hear “Doomsday is coming”. Scientists have revealed that the end of humans is as close to hundreds of millions of years. Does it sound more ? Well, don’t get carried away with the numbers. Doomsday is near. However, researchers have also revealed survivals plans, which include shifting the Earth’s orbit.
In a report published in Nautil, Columbia University astrophysicists Michael Hahn and Daniel Wolf Savin, have summed up and listed skills and techniques how to survive doomsday. According to them, there are various methods that people can do to save our planet Earth.
According to Dailymail, launching an asteroid to “alter the earth’s orbit” would help avoid the looming doomsday. Researchers figured out that the earth’s orbit hardly comes into the sun’s zone. If the sun goes brighter by 10 percent in every billion years, the Earth’s atmospheric layer of carbon dioxide would face depletion.
With no carbon dioxide, plants will die, which in turn reduce the oxygen level. And humans would run short of breath.
‘If we fired a 100 km [62 mile] wide asteroid on an elliptical orbit that passed close to the Earth every 5,000 years, we could slowly gravitationally nudge the planet’s orbit farther away from the sun, provided that we don’t accidentally hit the Earth,’ the authors said.
Another method suggests “uploading the subconscious human minds on machine”. According to Inquistr, researchers said that progress in neuroscience and computer system would help change biological process into robotic replacements. It will take few million years to achieve the state.
In another method, researchers said that forming a giant solar sail around 20 times diameter of the earth would help drag the planet away from the sun. It needs to interact with the photons from the sun. It is same like how a kite flies in the wind.
‘Strategies like these could, in principle, keep the Earth in the habitable zone until the sun expands into a red giant,’ the astrophysicists explain.
According to Global Catastrophic Risk 2016, threats like climate change, nuclear war, and other natural catastrophes are perilous to human’s existence.
