Quote of the Day
The sun, with all those planets revolving around it and dependent on it, can still ripen a bunch of grapes as if it had nothing else in the universe to do.
If the rate of expansion one second after the Big Bang had been smaller by even one part in a hundred thousand million million, it would have recollapsed before it reached its present size. On the other hand, if it had been greater by a part in a million, the universe would have expanded too rapidly for stars and planets to form.
One in 200 stars has habitable Earth-like planets surrounding it - in the galaxy, half a billion stars have Earth-like planets going around them - that's huge, half a billion. So when we look at the night sky, it makes sense that someone is looking back at us.
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.
In spite of the opinions of certain narrow-minded people, who would shut up the human race upon this globe, as within some magic circle it must never outstep, we shall one day travel to the moon, the planets, and the stars, with the same facility, rapidity, and certainty as we now make the voyage from Liverpool to New York!
We can allow satellites, planets, suns, universe, nay whole systems of universes, to be governed by laws, but the smallest insect, we wish to be created at once by special act.
Put two ships in the open sea, without wind or tide, and, at last, they will come together. Throw two planets into space, and they will fall one on the other. Place two enemies in the midst of a crowd, and they will inevitably meet; it is a fatality, a question of time; that is all.
If we ever start communicating with living creatures from other planets, the number one priority is, how are you going to communicate information? Even between different cultures here on Earth, you get into communication problems.
I won't say that I'm an agnostic, since agnosticism maintains that one cannot know... but I'm not averse to the idea of some intelligence or some organizing force that set up the initial conditions of the universe in such a way that ultimately generated stars, planets and life.
B. F. Skinner
I like science fiction and physics, things like that. Planets being sucked into black holes, and the various vortexes that create possibility, and what happens on the other side of the black hole. To me it's the microcosmic study of the macrocosmic universe in man, and that's why I'm attracted to it.
The stars look the same from night to night. Nebulae and galaxies are dully immutable, maintaining the same overall appearance for thousands or millions of years. Indeed, only the sun, moon and planets - together with the occasional comet, asteroid or meteor - seem dynamic.
There are several sorts of religions, not only in different parts of the island, but even in every town; some worshipping the sun, others the moon or one of the planets.
If you see a whole thing - it seems that it's always beautiful. Planets, lives... But up close a world's all dirt and rocks. And day to day, life's a hard job, you get tired, you lose the pattern.
Ursula K. Le Guin
And then when I went to Chicago, that's when I had these outer space experiences and went to the other planets.
I am sorry to say that there is too much point to the wisecrack that life is extinct on other planets because their scientists were more advanced than ours.
John F. Kennedy
When friendship disappears then there is a space left open to that awful loneliness of the outside world which is like the cold space between the planets. It is an air in which men perish utterly.
Philosophically, the universe has really never made things in ones. The Earth is special and everything else is different? No, we've got seven other planets. The sun? No, the sun is one of those dots in the night sky. The Milky Way? No, it's one of a hundred billion galaxies. And the universe - maybe it's countless other universes.
Neil deGrasse Tyson
Good men are the stars, the planets of the ages wherein they live, and illustrate the times.
Nature hasn't gone anywhere. It is all around us, all the planets, galaxies and so on. We are nothing in comparison.
Planets move in ellipses with the Sun at one focus.
We think that life develops spontaneously on Earth, so it must be possible for life to develop on suitable planets elsewhere in the universe. But we don't know the probability that a planet develops life.
Two nations between whom there is no intercourse and no sympathy; who are as ignorant of each other's habits, thoughts, and feelings, as if they were dwellers in different zones, or inhabitants of different planets. The rich and the poor.
It would take six months to get to Mars if you go there slowly, with optimal energy cost. Then it would take eighteen months for the planets to realign. Then it would take six months to get back, though I can see getting the travel time down to three months pretty quickly if America has the will.
Accordingly, since nothing prevents the earth from moving, I suggest that we should now consider also whether several motions suit it, so that it can be regarded as one of the planets. For, it is not the center of all the revolutions.
The bottom line is that finding orphan planets - small, faint, and located who-knows-where - is not for the faint of heart. The task is comparable to observing a match flame at the distance of Pluto. The WISE satellite, a hi-tech, space-based infrared telescope especially suited for such work, has found only a few.
