Stephen Hawking believed that people must leave the earth to avoid annihilation.
In a set of papers published posthumously on Tuesday, Hawking wrote that climate change and the possibility of nuclear war war put people in serious danger and adds that the latter is probably the biggest threat to humanity. The scientist, who died in March, wrote in Short answers to the big questions that people treat the earth with “ruthless indifference” that can lead to our own extinction if we can not find another home. 19659011] “In one way or another, I think it is almost inevitable that either a nuclear weapon confrontation or an environmental disaster will destroy the earth sometime in the next 1000 years,” Hawking wrote.
Hawking said it was difficult for him to maintain his optimism in the light of all the problems in the world, especially political instability and global warming. The population is getting too big for this planet, and physical resources quickly expire, he pointed out. A number of problems – including deforestation, extinction of animal species, rising temperatures and lack of water – can be solved, but we do not take appropriate measures, Hawking wrote.
He said researchers have an obligation to inform the public about the dangers we face, even though politicians who deny the existence of artificial climate change ignore these warnings. If it has not already happened, global warming can be self-sustaining soon, Hawking wrote. For example, melting of icecaps in the Arctic and Antarctica can reduce the amount of solar energy that reflects back into space, which would then increase global temperature even more.
The Earth may finally look like Venus Hawking said with sulfuric acid and a boiling temperature of 482 degrees Fahrenheit.
In addition, a catastrophic asteroid collision is inevitable, Hawking wrote. (The latest major effect, which thought it had dried out dinosaurs, occurred 66 million years.) As a more immediate threat, Hawking said he was concerned about a possible nuclear war and said that there is enough nuclear weapons to destroy people several times . 19659016] Even though we fly to another planet, it’s not possible to save millions of other species. Their extinction, Hawking said, “will be on our conscience as a race.”
Although we have no other place to go right now, Hawking said that people are explorers and must channel their curiosity to find new homes. Researchers have proved that the earth is not flat and brought people to the moon; Now it’s time to explore new solar systems, he wrote.
“We must resume the excitement of space travel in the early 1960s,” Hawking wrote. “Spread may be the only one that saves us from ourselves.”
