A Quote by Deke Slayton
I feel that I'm in on the ground floor of something that human beings will be concentrating on for the next 1,000 years-if we don't destroy ourselves in the meantime. It's possible that 50 years from now we're going to end up out of this solar system, batting around the universe, at least within our galaxy, investigating other stars and other systems.

We've got to somehow stabilize our connection to nature so that in 50 years from now, 500 years, 5,000 years from now there will still be a wild system and respect for what it takes to sustain us.
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.
I tell my students, with a feeling of pride that I hope they will share, that the carbon, nitrogen, and oxygen that make up ninety-nine per cent of our living substance were cooked in the deep interiors of earlier generations of dying stars. Gathered up from the ends of the universe, over billions of years, eventually they came to form, in part, the substance of our sun, its planets, and ourselves. Three billion years ago, life arose upon the earth. It is the only life in the solar system.
Despite the immense distance between our own solar system (including the earth) and the nearest other solar systems, a journey from one system to another is theoretically possible, once an unlimited source of power is developed.
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.
Because of Hubble and other telescopes, we've now discovered that there are probably planets around every star, or virtually every star. There are solar systems around most stars. And the fact that we're here on a planet, Earth, means that it's likely there's lots of other Earths out there.
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.
In less than a hundred years, we have found a new way to think of ourselves. From sitting at the center of the universe, we now find ourselves orbiting an average-sized sun, which is just one of millions of stars in our own Milky Way galaxy.
A rise of 5C would be a temperature the world has not seen for 30 to 50 million years. We've been around only 100,000 years as human beings. We don't know what that's like.
Without investments in research and science that will create the next Apple, create the next new innovation that will sell products around the world, we will lose. If we're not training engineers to make sure that they are equipped here in this country, then companies won't come here. Those investments are what's going to help to make sure that we continue to lead this world economy not just next year, but 10 years from now, 50 years from now, a hundred years from now.
While the Copernican principle comes with no guarantees that it will forever guide us to cosmic truths, it's worked quite well so far: not only is Earth not in the center of the solar system, but the solar system is not in the center of the Milky Way galaxy, the Milky Way galaxy is not in the center of the universe, and it may come to pass that our universe is just one of many that comprise a multiverse. And in case you're one of those people who thinks that the edge may be a special place, we are not at the edge of anything either.
If all the insects were to disappear from the earth, within 50 years all life on earth would end. If all human beings disappeared from the earth, within 50 years all forms of life would flourish.
We are killing, absolutely killing our energy business in this country. Now I'm all for alternative forms of energy, including wind, including solar, et cetera, but we need much more than wind and solar. You look at our miners, Hillary Clinton wants to put all the miners out of business. There is a thing called clean coal. Coal will last for 1,000 years in this country. Now we have natural gas and so many other things because of technology. We have unbelievable, we have found over the last seven years, we have found tremendous wealth under our feet. So good.
When we gaze at a star in the Milky Way which is 50,000 light-years away from our sun, we are looking back 50,000 years in time." "The idea is much too big for my little head." "The only way we can look out into space, then, is to look back in time. We can never know what the universe is like now. We only know what it was like then. When we look up at a star that is thousands of light-years away, we are really traveling thousands of years back in the history of space.
I'm absolutely positive about human survival. We will continue to develop our civilisation and expand not just on Earth, but also across the solar system, the galaxy, even the entire universe.
We live on a hunk of rock and metal that circles a humdrum star that is one of 400 billion other stars that make up the Milky Way Galaxy which is one of billions of other galaxies which make up a universe which may be one of a very large number, perhaps an infinite number, of other universes. That is a perspective on human life and our culture that is well worth pondering.
