A Quote by Chris Hadfield
The world, when you look at it, it just can't be random. I mean, it's so different than the vast emptiness that is everything else, and even all the other planets we've seen, at least in our solar system, none of them even remotely resemble the precious life-giving nature of our own planet.

When I grew up as a kid, we didn't know there were any other planets outside of our own solar system. It was widely speculated that planet formation was an incredibly rare event and that it's possible that other planets just don't exist in our galaxy, and it's just this special situation where we happen to have planets around our sun.
There's no doubt that the search for planets is motivated by the search for life. Humans are interested in whether or not life evolves on other planets. We'd especially like to find communicating, technological life, and we look around our own solar system, and we see that of all the planets, there's only one that's inhabited.
Estimates are that at least 70 per cent of all stars are accompanied by planets, and since the latter can occur in systems rather than as individuals (think of our own solar system), the number of planets in the Milky Way galaxy is of order one trillion.
We call our intuition our sixth sense, but in reality it would be called our first sense, because it's rooted in quantum nature of reality. It was around long before our solar system and our planetary system were even formulated or even organized. It is at the basis of how our normal sensing works. So instead of being our sixth sense or even â€" using the parapsychological term â€" "extrasensory perception," it's not. It's at the basis of our perception, and that's the quantum world.
Marriage is so unlike everything else. There is something even awful in the nearness it brings. Even if we loved someone else better than - than those we were married to, it would be no use. I mean, marriage drinks up all our power of giving or getting any blessedness in that sort of love. I know it may be very dear, but it murders our marriage, and then the marriage stays with us like a murder, and everything else is gone.
No one planet can tell us everything about the universe, but Neptune seems to hold more than its share of information about the formation of our own solar system - as well as the solar systems beyond.
The secret of our success on planet Earth is space. Lots of it. Our solar system is a tiny island of activity in an ocean of emptiness.
We really have the most beautiful planet in our solar system. None other can sustain life like we know it. None other has blue water and white clouds covering colorful landmasses filled with thriving, beautiful, living things like human beings.
Nature has endowed the earth with glorious wonders and vast resources that we may use for our own ends. Regardless of our tastes or our way of living, there are none that present more variations to tax our imagination than the soil, and certainly none so important to our ancestors, to ourselves, and to our children.
No matter how you measure it, whether you measure the amount of mass or you measure the number of bodies, most of our solar system exists out beyond the orbits of the asteroids. So we could not have claimed to know our own solar system until Voyager had toured the giant planets.
From an entertainment point of view, the Solar System has been a bust. None of the planets turns out to have any real-estate potential, and most of them are probably even useless for filming Dune sequels.
In the next century or two, we humans will have planet-finder telescopes that span our solar system with mirrors strewn from here to Jupiter, giving us enormous angular resolution so we can do the kind of science that a self-respecting advanced civilization ought to be doing. We should someday be imaging the continents on other planets. We can't do that yet, but aliens can do that already, so they know we are here.
When I was a kid, I was obsessed with different planets in the solar system, and I used to create, for every single planet, a different alien race with a certain kind of pet, a certain kind of house, a certain kind of water system, and everything.
This is a living planet. Look around. Mars, Venus, Jupiter. Look beyond our solar system. Where else is there a place that works, that is just right for the likes of us? It has not happened just instantly. It is vulnerable to our actions. But it's the result of four and a half billion years of evolution, of change over time. And it changes every day, all the time. It would be in our interest to try to maintain a certain level of stability that has enabled us to prosper, to not wreck the very systems that give us life.
Today the human race is a single twig on the tree of life, a single species on a single planet. Our condition can thus only be described as extremely fragile, endangered by forces of nature currently beyond our control, our own mistakes, and other branches of the wildly blossoming tree itself. Looked at this way, we can then pose the question of the future of humanity on Earth, in the solar system, and in the galaxy from the standpoint of both evolutionary biology and human nature. The conclusion is straightforward: Our choice is to grow, branch, spread and develop, or stagnate and die.
So those who wished for some central cosmic purpose for us, or at least our world, or at least our solar system, or at least our galaxy, have been disappointed, progressively disappointed. The universe is not responsive to our ambitious expectations.
