I trust Stephen Hawking's word when it comes to black holes and quantum mechanics, but I'm more dubious when the famous cosmologist says, as he does in an upcoming BBC special, that it is urgent for humans to colonize another planet in the face of catastrophes like climate change, asteroid strikes, epidemics and overpopulation. 
  
 The Beeb is resurrecting its long-running science program, "Tomorrow's World" with a documentary called "Expedition New Earth," in which Hawking says the human species must set up shop beyond Earth within the next hundred years in order to ensure the survival of our species, according to the Telegraph. 
  
 I really hope someone on the show's production team, or the BBC's promotions people, or maybe the outlets picking up the story are misrepresenting Hawking's level of hysteria and urgency here, because it's sorely lacking in the logic department. 
  
 The most likely worlds for colonization are our moon or Mars (which is also Elon Musk's target of choice for a colony in the next century), and in case you hadn't heard, neither of these places are habitable. Even if Earth were to suffer the catastrophes that Hawking worries about -- and they all worry me, too -- it would still be more habitable than the moon or Mars. 
  
 This is to say nothing of the trip to each place, which is highly risky, expensive and involves exposure to an awful lot of cosmic radiation and weightlessness that can do very real damage to the human body, especially on the long trip to Mars. 
  
 I feel like I should be able to drop the mic here, but openly disagreeing with one of the smartest men on Earth demands a little extra diligence. 
  
 So to be clear, I think pursuing a small human colony is a great idea. The scientific discoveries and technological innovations that will come out of such a venture are well worth the effort. 
  
 But this notion that Mars or the moon is our salvation because the end of the world is nigh is really silly. 
  
 Let's just run through the scenarios: rising sea levels, famine, epidemics, ecological collapse... If all those came to pass, even all at the same time, Earth would still be more habitable than anywhere else in our solar system. Really, you can't undersell the value of a working magnetic field and an atmosphere, even one with a little too much carbon dioxide in it. 
  
 What about nuclear war though? Well, that depends on where you are and if it has been contaminated by as much radiation as the entire planet of Mars gets blasted by all the time. You might need to go underground, which is what we'd also have to do on Mars. 
  
 That big asteroid strike could be a really big problem for us, though, right? Yes, it could, but I'm not sure that running away to Mars, which neighbors the asteroid belt, is a better option. 
  
 But what if society just completely falls apart and we devolve into anarchic, violent states thanks to any combination of the above? Wouldn't we want to somewhere we could just start over? 
  
 Again, just cleaning up our own mess and starting over by rising from the rubble seems more practical, but what if another planet was an option? 
  
 This gets at the real urgent problem that we should aim to solve long before we start looking for a panacea beyond our own planet. I'm talking about the very ugly but real conundrum of global inequality. Many of the disasters Hawking warns of are much more likely to impact, say, the low-income residents of low-lying Bangladesh than the average Forbes reader (or contributor). 
  
 Just as our terrestrial problems are more likely to affect the poor, pie-in-space solutions like a Martian colony are likely to be an option for only the wealthy and less apocalyptically challenged among us when the stuff finally hits the fan. Martian condos certainly aren't going to be cheap, after all. 
  
 This is why the off-planet colonies in so many space operas like "The Expanse," "Elysium" and even "Star Wars" tend to be run by the bad guys. Colonizing a new planet would be just as much about who gets left behind as it would be about who gets to start over. 
  
 Yes, there are all kinds of problems that we face on Earth, but all the solutions are here too. All the natural resources, manufacturing facilities, intellectual capital and other tools we use to, you know, live, are here. We'd have to recreate them under far more difficult conditions anywhere else. 
  
 You think recycling and conservation are a pain? Just wait until you have to try to grow potatoes in toxic Martian soil and reduced gravity while dealing with your latest bout of radiation poisoning. Yet somehow, the grass is always greener for some people, even when it's on a dead Red Planet. ||||| Updated | Renowned physicist Stephen Hawking has warned that humanity needs to become a multi-planetary species within the next century in order to avoid extinction. 
  
 Hawking made the prediction in a new documentary called Expedition New Earth, which is set to be released this summer as part of the BBC’s Tomorrow’s World science season. 
  
 Existential risks include climate change, overpopulation, epidemics and asteroid strikes, according to Hawking. 
  
 In his program, Hawking will explore the latest advances in astronomy, biology and rocket technology that will make it possible to live on Mars—from plasma rockets to human hibernation. 
  
 “In this landmark series, Expedition New Earth, [Hawking] enlists engineering expert professor Danielle George and his own former student, Christophe Galfard, to find out if and how humans can reach for the stars and move to different planets,” the BBC said. “The journey shows that Prof Hawking’s ambition isn’t as fantastical as it sounds—that science fact is closer to science fiction than we ever thought.” 
  
 Efforts to create a human colony on Mars are already underway, with billionaire Elon Musk hoping to establish a settlement within the next few decades through his aerospace firm SpaceX. “I don’t have a doomsday prophecy,” Musk said in 2016, “but history suggests some doomsday event will happen.” 
  
 Hawking has repeatedly called for humans to colonize the moon and Mars as an insurance policy against an apocalyptic catastrophe on Earth. “The moon could be a base for travel to the rest of the solar system,” Hawking said in a 2008 lecture marking NASA’s 50th anniversary, adding that Mars would be “the obvious next target.” 
  
 Hawking predicted last year that the chance of a species-ending event on Earth was a “near certainty” when all possibilities were taken into consideration. 
  
 “Although the chance of disaster to planet Earth in a given year may be quite low, it adds up over time, and becomes a near certainty in the next 1,000 or 10,000 years,” Hawking told the Oxford University Union in November. 
  
 “By that time, we should have spread out into space and to other stars, so a disaster on Earth would not mean the end of the human race.” 
  
 Despite the dire warning, Hawking did have some positive news for the assembled students. He pointed to how our fundamental understanding of the universe has advanced in his lifetime and said it is a “glorious time to be alive and doing research into theoretical physics.” 
  
 He added: “Our picture of the universe has changed a great deal in the last 50 years and I am happy if I have made a small contribution. The fact that we humans, who are ourselves mere fundamental particles of nature, have been able to come this close to understanding the laws that govern us and the universe is certainly a triumph.” 
  
 Update: This article has been update to include a comment from the BBC on the Expedition New Earth series. ||||| Humans will need to colonise another planet within one hundred years to ensure our survival, according to Professor Stephen Hawking. 
  
 The astrophysicist has made a new documentary, Expedition New Earth, as part of the BBC’s new science season Tomorrow’s World. In it he will claim that time is running out for Earth and if humanity is to survive climate change, asteroid strikes, epidemics and overpopulation we will need to leave our planet and venture further afield. 
  
 In the landmark series, Prof Hawking and his former student Christophe Galfard will travel the world to find out how humans could live in outer space. 
  
 It is 14 years since the BBC cancelled its future-gazing series Tomorrow’s World after 38 years on air, but the corporation and the scientists involved promise the new season will be even better. |||||

Stephen Hawking is giving humanity a tall order: Colonize Mars in the next century or watch as life on Earth fizzles out. After last year claiming that humans have 1,000 years left on Earth, Hawking says in a new documentary that we instead have about 100 years until we'll need to jump ship as Earth is overwhelmed by overpopulation, climate change, disease, and artificial intelligence. It might be a bit premature to start packing, but the BBC's Expedition New Earth will explore technological and scientific advances that will enable life in space or a colony on another planet, reports the Telegraph. It will show "Hawking's ambition isn't as fantastical as it sounds—that science fact is closer to science fiction than we ever thought," the BBC says, per Newsweek. Elon Musk of SpaceX is already planning to send humans to Mars in the next decade. But while a Mars colony is a good idea, bringing new scientific discoveries, columnist Eric Mack says Hawking needs to give his head a shake if he honestly believes Mars, the moon, or anywhere else in our solar system will be more hospitable than Earth even after a host of disasters. "Just cleaning up our own mess and starting over by rising from the rubble seems more practical" and more affordable than figuring out how to grow food or survive radiation poisoning on Mars, he writes at Forbes. The solution to all of our problems is here on Earth, he adds. "Yet somehow, the grass is always greener for some people, even when it's on a dead Red Planet."
