People might well have argued that it was a waste of money to send Columbus on a wild goose chase. Yet the discovery of the New World made a profound difference to the old. If nothing else, we wouldn’t have had a Big Mac or KFC.
Stephen Hawking
We could have a base on the Moon within 30 years, reach Mars in 50 years, and explore the moons of the outer planets in 200 years.
Stephen Hawking
There will be those who argue that it would be better to spend our money solving the problems of this planet like climate change and pollution rather than wasting it on a possibly fruitless search for a new planet. I am not denying the importance of fighting climate change and global warming, but we can do that and still spare a quarter of a percent of world GDP for space. Isn’t our future worth a quarter of a percent?
Stephen Hawking
In 1962 President Kennedy committed the U.S. to landing a man on the Moon by the end of the decade. This was achieved on time by the Apollo 11 mission in 1969.
Stephen Hawking
After the last Moon landing in 1972, with no future plans for further manned space flight, public interest in space declined.
Stephen Hawking
A new manned spaceflight program would do a lot to restore public enthusiasm for space and for science generally. Robotic missions are much cheaper and may provide more scientific information but they don’t catch the public imagination in the same way, and they don’t spread the human race into space, which I am arguing should be our long-term strategy.
Stephen Hawking
What will we find when we go into space? Is there alien life out there, or are we alone in the Universe?
Stephen Hawking
even if the probability of life appearing on a suitable planet is very small, since the Universe is infinite, life would have appeared somewhere.
Stephen Hawking
Why haven’t we heard from anyone out there? One view is expressed in this Calvin cartoon. The caption reads “Sometimes I think that the surest sign that intelligent life exists elsewhere in the Universe is that none of it has tried to contact us.”
Stephen Hawking
It is not clear that intelligence confers a long-term survival advantage. Bacteria and insects will survive quite happily even if our so-called intelligence leads us to destroy ourselves.
Stephen Hawking
What are the possible sites of a human colony in the solar system? The most obvious is the Moon. It is close by and relatively easy to reach. We have already landed on it and driven across it in a buggy.
Stephen Hawking
There is no sign of life on Mars now, but if we found evidence that life had once existed that would indicate that the probability of life developing on a suitable planet was fairly high.
Stephen Hawking
There are around a thousand stars within 30 light years of Earth. If one percent of these have Earth-sized planets in the Goldilocks zone, we have 10 candidate new worlds.
Stephen Hawking
The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing?
Stephen Hawking
I’m an optimist, I think we have a good chance of avoiding both Armageddon and a new Dark Age.
Stephen Hawking
[On the Simpsons – If he couldn’t rescue the entire human race from Armageddon, he could at least get to Los Angeles in time to] Save Lisa’s brain.
Stephen Hawking
[On Homer Simpson’s theory of a donut-shaped universe] Interesting. I may have to steal it.
Stephen Hawking
How do we know we are not just characters in a computer-generated soap opera?
Stephen Hawking
[To Sheldon on The Big Bang Theory] You made an arithmetic mistake on page two. It was quite a boner.
Stephen Hawking
There’s nothing like the Eureka moment of discovering something that no one knew before. I won’t compare it to sex, but it lasts longer.
Stephen Hawking
A minute to learn, the lifetime of the universe to master.
Stephen Hawking
If the human race is to continue for another million years, we will have to boldly go where no one has gone before.
Stephen Hawking
