Quote of the Day
Is it not careless to become too local when there are four hundred billion stars in our galaxy alone.
A. R. Ammons
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.
Looking up and out, how can we not respect this ever-vigilant cognizance that distinguishes us: the capability to envision, to dream, and to invent? the ability to ponder ourselves? and be aware of our existence on the outer arm of a spiral galaxy in an immeasurable ocean of stars? Cognizance is our crest.
When you look at the stars and the galaxy, you feel that you are not just from any particular piece of land, but from the solar system.
Who are we? We find that we live on an insignificant planet of a humdrum star lost in a galaxy tucked away in some forgotten corner of a universe in which there are far more galaxies than people.
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.
The lunar flights give you a correct perception of our existence. You look back at Earth from the moon, and you can put your thumb up to the window and hide the Earth behind your thumb. Everything you've ever known is behind your thumb, and that blue-and-white ball is orbiting a rather normal star, tucked away on the outer edge of a galaxy.
There are at least as many galaxies in our observable universe as there are stars in our galaxy.
It is mind-boggling to me that the Almighty power created everything I see; the Bible says that God created the entire universe just so he could create this galaxy just so he could create Earth so he could create human beings so he could create a family.
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.
We're electrical items and when we die the electricity goes somewhere else. When we die our energy goes into the galaxy.
The priceless galaxy of misinformation called the mind.
A typical neuron makes about ten thousand connections to neighboring neurons. Given the billions of neurons, this means there are as many connections in a single cubic centimeter of brain tissue as there are stars in the Milky Way galaxy.
Asteroids have us in our sight. The dinosaurs didn't have a space program, so they're not here to talk about this problem. We are, and we have the power to do something about it. I don't want to be the embarrassment of the galaxy, to have had the power to deflect an asteroid, and then not, and end up going extinct.
Neil deGrasse Tyson
Here's my definition of a great beach read - a fabulous story that sucks me in like a black hole and when it's over, it jettisons my bones across the galaxy with a hair on fire mission to convince everyone I know that they must read that book or they will die.
Dorothea Benton Frank
If you set out in a spaceship to find the one planet in the galaxy that has life, the odds against your finding it would be so great that the task would be indistinguishable, in practice, from impossible.
How can you look at the galaxy and not feel insignificant?
Keep up the good work, if only for a while, if only for the twinkling of a tiny galaxy.
There may be aliens in our Milky Way galaxy, and there are billions of other galaxies. The probability is almost certain that there is life somewhere in space.
I think when people mean that Discworld books have become darker they really mean the series is growing up. In 'The Colour of Magic' most of the city is set alight. It's a joke, in much the same way that the Earth is destroyed almost at the start of Douglas Adams's 'The Hitchhikers Guide to the Galaxy.'
I had always seen myself as a star; I wanted to be a galaxy.
Should we find a second form of life right here on our doorstep, we could be confident that life is a truly cosmic phenomenon. If so, there may well be sentient beings somewhere in the galaxy wondering, as do we, if they are not alone in the universe.
The spiral in a snail's shell is the same mathematically as the spiral in the Milky Way galaxy, and it's also the same mathematically as the spirals in our DNA. It's the same ratio that you'll find in very basic music that transcends cultures all over the world.
While human space travel is daunting, machines - with their indefinitely long lifetimes - could travel the galaxy. It might make little difference to them that bridging the distance from one star to the next could take hundreds of thousands of years or more.
Are we the only members of the Galaxy that can actually understand what a galaxy is? Could Homo sapiens really be the pinnacle of Creation - the cleverest critters in the cosmos? If we learn the answer is 'no,' that would affect our philosophies forever.
