Stephen Hawking suggests to find life on other planets for survival of human species.
While attending Starmus Festival as a speaker in Trondheim (Norway), Prof. Hawking stated that it is essential to step on Moon and try to find life on other planets as well.
This festival aims to celebrate science and arts. While this was about spreading out in space,
Hawking said that the leading nations must aim to land on the moon, build a lunar base, and send people to Mars.
He even gave an approximate deadline for these projects.
Hawking believes that leading nations should send astronauts to the Moon by 2020. He suggests that these nations must aim to send people on Mars by 2025 and build the lunar base in next 30 years. He believes that this would give humanity a sense of purpose and it's like he thinks we are running out of time.
This single goal will unite competitive nations to face challenge of human extinction together and maybe help humanity survive for another million years.
Prof Hawking explained that human space travel is essential for the future of humanity precisely because the Earth was under threat from climate change as well as diminishing natural resources.
"We are running out of space and the only places to go to are other worlds. It is time to explore other solar systems. Spreading out may be the only thing that saves us from ourselves. I am convinced that humans need to leave Earth," the Cambridge University theoretical physicist explained.
He believes that Earth is under a threat and there is a need to explore space for the sake of saving human species. Our only chance to survive is to explore space and go where no one else has gone before. That's what he thinks.
I agree about the earth's condition that might be getting worse. We underestimate nature. Population has crossed 7 billion count, this count will rise in coming years. The point of extinction might be far by this time, this vision to save humanity is worth a thought. But the way we have took environment for granted for so many years on this planet, how about we first learn to care for the planet we already have. Shouldn't we focus more on the ways to survive here? This sounds more practical to me than pursuing a planet hunt to find a twin brother of earth.
Hawking is not the only one with this view. Many scientists believe that the purpose of being a human is to help humanity survive. The prior way to do this is to extend the human existence timeline as much as possible. Climate change and diminishing resources are few of the signs that grabs these concerns.
Hawking shed a light on the fact. Earth might not survive much longer and we need to explore space and other planets in the event that we need to move human life elsewhere. We need to start investing more research and time towards this approach, as soon as possible.
Prof Hawking said that there was no long-term future for our species staying on Earth: it would either be hit by an asteroid again or eventually engulfed by our own Sun. He added that travelling to distant worlds would "elevate humanity".
Hawking is concerned that another asteroid might hit us or the sun might engulf us, in which case humans will likely become extinct. The only solution is to move to distant worlds and help us prevent our own extinction.
NASA is not planning a trip to Moon again, but is more focused towards sending astronauts to Mars by 2030. China may fly to the Moon soon.
I agree with Hawking. Colonization on other similar planets might be a good idea. If we can find a reachable planet that sustains life. Scientists must find a way before we become extinct or over populate our planet; but neither of those are likely to happen in our own lifetime. Hawking stated in his recent appearances that we have 100 years to expand colonies to other planets or we will face extinction. Of course he says that because he knows most people on this planet right now will not live for another 100 years.
"To leave Earth demands a concerted global approach, everyone should join in. We need to rekindle the excitement of the early days of space travel in the sixties."
"If humanity is to continue for another million years, our future lies in boldly going where no one else has gone before.
"I hope for the best. I have to. We have no other option"
Humans have come a long way from stone age to social media age. Survival of our species is very important, but we're probably not going to live on another planet anytime within the next 100 years.
