In an upcoming BBC program, Stephen Hawking has a new message for humanity: Get off Earth within the next 100 years or perish. In order to survive as a species, humans must colonize other planets.
But Canadian astronaut Chris Hadfield has previously said that humans just aren't ready to live on other worlds. In 2015, he visited Business Insider to discuss his thoughts on where humans will go next and why.
Hadfield became a mainstream figure thanks to his YouTube videos from space and wide social media presence. Now retired, Hadfield is the best-selling author of "An Astronaut's Guide to Life on Earth."

Natural selection would continue to operate, but different traits would be more beneficial in various environments.
To me, the only scenarios that don’t seem “reasonable” to some extent are those which require that human nature cease to be human nature. The entire history (and known prehistory) of Earth makes it clear that people are always the same. The range of possible outcomes from any change in environment is limited by the fact that we are what we are.
The people who master space travel will be the people our grandkids work for. I would like it to be our grandkids who master it.
And in that vein, I’d like to see a bit more urgency about space exploration. I thought when we landed on the moon that we’d be on Mars thirty years later; as it turns out we can’t even get back to the moon. There just isn’t much interest. When they killed the manned space program, it was because they thought we could better spend that money helping the poor. Five decades later we still have lots of poor, but no men beyond a hundred miles from the surface, and we have to pay the Russians even to get there.
I do think that modern technology has made us feel sufficiently invulnerable. As a result, too many of us feel safe in rejecting common sense.
Agree. As a species we are dangerous.
The quarantine theory is interesting.
That’s a very good question. I never thought about it.
Could someone be making wild assumptions about what Hawkings is saying? Otherwise, i’m starting to think Steven just wants the attention, with each following warning more hysterical than the last one.
“David Bowie himself was extremely impressed.”
What passes for space science and who passes for astronauts is less impressive
“Being on more than one world, in more than one solar system increases the odds of remaining undiscovered by hunters.”
That could be. Or it could also be that just moving around attracts attention. It could also be that having many rabbit warrens in the forest increases the chance of the wolves knowing there are other rabbits in that forest, probably nearby. Wolf finds one rabbit, extrapolates/interrogates to find the rest of the rabbits.

“The satisfying of the human thirst for knowledge, and sometimes knowledge for which we don’t, at the time, have a practical reason for”
We don’t have enough time and money to take an “Edison approach” to learn how not to successfully land on Mars without first perfecting cheap and reliable ways to get bulk cargo into orbit.
Then how to get to and sustain a presence on the moon.
Then how to make fuel and structures on the moon, including spacecraft.
Then we can go to mars.
Skipping obvious precursor steps is not how we will get to mars.
I wish we had invested more in space science and less in guitar-playing Canadian astronauts
Ok you may not respect anything Hawking has done or does. He merely holds the Lucasin Chair for Mathematics, a chair once held by Newton & Dirac I would agree that mostly for the last 5 to 10 years he has become more of a public annoyance then a working physicist. I attribute this his infirmity, age, ego & these guys just burn out intellectually after awhile. They had the world stage and they want it back but now can no longer do anything significant to get it back. So they pop off every so often yelling the “aged/irrelevant scientist “ equivalent of “Get off my lawn!”.
Here’s his accomplishments

Lets compare with your resume!
“Our national IQ is our greatest resource. By importing in MILLIONS of folks with an average IQ of about 75, our national IQ is destined to go down and down and down. Our national IQ helped us become great. Being a realist is not negativity, it’s just life. Call me ahead of the curve. Here is a list of National IQ’s.”
The average IQ matters not a bit, except perhaps in terms of some social issues like crime.
What matters is the absolute number of very high IQs, which produce breakthroughs that benefit everyone. The US is still doing fine in that department, although China is worrisome simply because of the large potential pool of geniuses. One might almost think that America is favored by a higher power...
One very good use of LEGAL immigration is to import smart people from around the globe, BTW...
“Smile and nod at the nice cameraman or you won’t get your pudding, Stephen.”

“If an advanced civilization had come looking for intelligence on Earth as little as 10K years ago ...”
Yes, But had they come 2-3 thousand years earlier, they may have found an advanced stone based civilization - remnants of which are being discovered currently - we still have no idea what the pyramid complex at Giza was built for and what its purpose was; see Gobeki Tepi, buried deliberately 12,000 years ago - why and who are unknown; see evidence of a double comet strike - one ending the Ice age and another 1,000 years later causing the Younger Dryas. (This heralds another possible strike from the same Taurids group in the next 50 years as we pass through a denser portion of the group.)
Meanwhile, any evidences of civilizations before that time would be so degraded as to be unrecognizable or nearly so today.
“And 10K years is nothing in the life of the universe.”
And 10K years is nothing in the life of the Earth. And 10K years is nothing in the history of homo sapiens ... going back at least 250,000 years (according to mitochondrial DNA findings).
Dang, you are correct. Amazon prime with roku or Spectrum on demand.
So what do we do with all of the untrainable -84 IQ folks?
Re-introduce manual farm labor to keep them busy? Support them on “disability” for life (and the lives of their offspring?)
Pay for it out of the Magic Money Machine?
Why would a Canadian astronaut’s opinion matter? I don’t think that Canada has ever built a rocket capable of going beyond the upper atmosphere of earth. They hitch rides on other rockets. Not that that’s a bad thing but it’s kind of like asking some guy who’s rode a taxi a couple if times what kind of developments are coming up for next years taxicabs. I would, however, value his opinion on hockey. For future rocketry plans, I’ll ask a rocket scientist.
Chance is only increased if the precise location is known - there are just too many stars in any given direction to say that a target here comes from there.
Like the wolf finds a rabbit in one field, then extrapolates that rabbits ware found in fields, only to learn that the next field has no rabbits. How many fields must the wolf search for the next rabbit - given that there are countless fields? And what if he finds a lion in the field instead of a rabbit? Searching is dangerous. Stay home and be quiet is always the best option, unless one knows exactly where to look in 4 dimensions.
