We must leave this planet before we get hit by rocks or become part of a Ben Affleck movie

In a rare interview, Stephen Hawking said to the BBC that humans must move to another solar system in order to ensure the survival of the species. “Once we spread out into space and establish colonies, our future should be safe,” he said. Hawking made a similar suggestion back in June.


He believes that life on Earth could be wiped out by a nuclear disaster or a massive asteroid hitting the planet causing Armageddon with its Deep Impact. He said that, since we have no similar planets on our solar system, we would “have to go to another star” to find a suitable habitat.


Before humans could even dream of such a move, we would need to develop a viable means of transportation. Hawking proposed “matter/anti-matter annihilation” propulsion. He explained: “When matter and anti-matter meet up, they disappear in a burst of radiation. If this was beamed out of the back of a spaceship, it could drive it forward … It would take a lot of energy to accelerate to near the speed of light.”


Even at near-light speeds, it would take six years to reach a new star. While Hawking, 64, may not see our escape from Earth in his lifetime, he still wishes to see the planet from space.  “My next goal is to go into space; maybe Richard Branson will help me.”


Hawking was recently awarded the Royal Society’s Copley medal, their highest honor, for his work in theoretical physics and cosmology leading to classifications and further knowledge of black holes.


Lord Rees, president of the Royal Society, stated “Stephen Hawking has contributed as much as anyone since Einstein to our understanding of gravity. This medal is a fitting recognition of an astonishing research career spanning more than 40 years.”


In a statement issued by Hawking after learning of the award he said “This is a very distinguished medal, it was awarded to Darwin, Einstein and (Francis) Crick. I am honored to be in their company.”

@ Gatt:

First remark: The point is not that we actually can manage to protect (more efficiently) our hands; it's, mostly, that fire still burns...

Second remark: Try to see it the other way around: all the universe was/is/will be different from our own 'locality'; that'd make our region special, right? What's special about it? So, are we limited in time & space because we're not able to be everywhere at the same time? Definitely. Does this fact change the laws of the ['far'] universe? We do not know but, as far as we can see (literally!), the laws were/are/will be the same; what we - as the only known conscience of the universe - can say about this last statement is... unless otherwise proven.

Third remark: Well, 'likeliness' is akin to probability; as for other 'forces', 'forms of energy', dimensions, etc, what would be the point in consider them - if they 'exist' - if we're not aware of their manifestation? Certainly, we're limited; but, extrapolating to a «close minded line of thinking» leads me to believe there's another... could you elaborate on that, please?
The Laws of Physics are only as good as they reflect our world's behaviour; it's a metalanguage (a translating language...) of natural phenomena; so far, reason has gone hand-in-hand with observation; one's nothing, without the other.
Mathematics are tools (ok, a very special kind of tools); it has been built upon axioms, just like the one you've pictured; actually, like flatness is a special case of curvature, 1+1=2 is a special case, where 2 happens to be one of a series of [infinite?] possibilities; moreover, we cannot prove it's own axioms: Gödel's theorem asserts that mathematical axioms (the very basic ones) cannot be subject to proof; shocking as it might seem, it proves mathematical consistency: were we able to prove axioms, they could prove false...

Preface (we don't know better...): The problem is that we're as much 'gods' as gods can be. We know no other form of thinking nor other form of sensing (we do invent tools which help, though); we've got no comparative models and, even if we had, we would not understand them, most probably.
Many of General Relativity's peculiarities were due to 'insights' about how things could work, within a certain context (not Star Treck's); it happens that, most of those peculiarities were subject to proof and they've been proven, after GR was thought out; that, was a big 'win' towards our way of thinking. But, GR isn't the ultimate theory; nor, perhaps, Quantum Mechanics. Maybe there's room for another 'mind revolution'... or, Nature will show itself, 'undone'.
'Our equations' go way beyond our senses; maybe the four 'forces' we know today may have a more 'colourful' way of presenting themselves than just 'black' & 'white'. We're trying hard to find out.
Maybe you should know better, on what concerns our limitations... and our knowledge.
