A Quote by Neil deGrasse Tyson

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.
We are not at the center of ourselves, but instead - like the Earth in the Milky Way, and the Milky Way in the universe - far out on a distant edge, hearing little of what is transpiring.
If you want to see a black hole tonight, tonight just look in the direction of Sagittarius, the constellation. That's the center of the Milky Way Galaxy and there's a raging black hole at the very center of that constellation that holds the galaxy together.
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.
Our galaxy, the Milky Way, is one of 50 or 100 billion other galaxies in the universe. And with every step, every window that modern astrophysics has opened to our mind, the person who wants to feel like they're the center of everything ends up shrinking.
Science has an uncomfortable way of pushing human beings from center stage. In our prescientific stories, humans began as the focal point of Nature, living on an Earth that was the center of the universe. As the origins of the Earth and of mankind were investigated more carefully, it became clear that Nature had other interests beyond people, and the Earth was less central than previously hoped. Humankind was just one branch of the great family of life, and the Earth is a smallish planet orbiting an unexceptional sun quite far out on one arm of a run-of-the-mill spiral galaxy.
Discovering that our solar system has many more planets than we ever expected, and that most of them are ice dwarfs rather than like Earth and the other rocky terrestrials, is just another step in the revolution in viewpoint that removed the Earth from the center of the physical universe and makes Earth all the more special.
Crazy may not be the one who says the sun is the center of the solar system, the Earth is round, and someday people might fly. It may be those who laugh at such words whose minds are lost.
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.
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.
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.
There are lots of ideas which extend the Copernican principle one step further. We went from the solar system to the galaxy to zillions of galaxies and now to realising even that isn't all there is.
We live in a modest system, a galaxy called the Milky Way. If we named every star in the Milky Way and put them in the Hollywood telephone directory and stacked those telephone directories up, we'd have a pile of telephone directories 70 miles high.
There is a point of view among astronomical researchers that is generally referred to as the Principle of Mediocrity. ... If the Sun and its retinue of worlds is only one system among many, then many other systems will be like ours: home to life. Indeed, to the extent that this is true, we should be prepared for the possibility that, even in the Milky Way galaxy, billions of planets may be carpeted by the dirty, nasty business known as life.
Kid says to me, "You play baseball? What position? Left out?" and gets a big laugh from the rest of the class. Kid is only one person out of 6.792 billion humans on this planet. This planet is only one-eighth of the solar system, whose sun is one of two billion stars in the Milky Way galaxy. Put it that way, the comment loses it's importance.
The cosmic calendar compresses the local history of the universe into a single year. If the universe began on January 1st it was not until May that the Milky Way formed. Other planetary systems may have appeared in June, July and August, but our Sun and Earth not until mid-September. Life arose soon after. We humans appear on the cosmic calendar so recently that our recorded history occupies only the last few seconds of the last minute of December 31st.
If consciousness is the ground of being rather than an epiphenomenon of physical processes, we may find that a basic question asked by modern astronomy and space science- 'Is there life out there?'- should be rephrased. Organic life, as well as intelligence, may already be a property enmeshed in the fabric of the cosmos, brought to fruition through the spiraling dynamics of the solar system and the galaxy, built into the structure of the universe itself.
