Proof of the black hole is a tremendous amount of mass inside a very small volume. There's 4 million times the mass of our sun within a region that's comparable to the size of our solar system.
The whole of the hydrogen on the earth might be transformed at once and the success of the experiment published at large to the universe as a new star.
We know too little about how life began on Earth to lay confident odds. It may have involved a fluke so rare that it happened only once in the entire galaxy. On the other hand, it may have been almost inevitable, given the right environment.
Dark matter is everywhere. In this room. Everywhere.
The match the whole world, Jupiter, Saturn , Venus... Or anywhere else is waiting for.
When Uncle Bob (or Ted or Ray) promised to send a shooting star over the house to mark a young listener's birthday, the young listener, who had hung out the window for an hour without seeing the star, questioned not Uncle Bob (or Ted or Ray), but his own eyesight.
Over his shoulder I saw a star fall. It was me.
I like to describe my life as a black hole with a little light out there.
Now the bright morning-star, day's harbinger, comes dancing from the east.
A black hole really is an object with very rich structure, just like Earth has a rich structure of mountains, valleys, oceans, and so forth. Its warped space whirls around the central singularity like air in a tornado.
It's not just a sunset; it's a moonrise too.
I think the dual existence thing is a regular pastime for all human beings, and for that matter anything in this universe.
To reflect upon the event horizon is a great deal more awe-inspiring than a burning bush or a wooden statue that weeps or pees or bleeds.
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.
There are stars, stars, scattered stars, blackness all between. They ripple and fold and bend, and they rush toward him, rush by him. Their colors are blazing and pure as angels' eyes.
...and the Universe, ... will explode later for your pleasure.
He sighed. "The clouds I can handle. But I can't fight with an eclipse.
I'm a blackstar. I'm a blackstar.
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.
It shows you exactly how a star is formed; nothing else can be so pretty! A cluster of vapor, the cream of the milky way, a sort of celestial cheese, churned into light.
We haven't yet found a speck of evidence for biology on another world, so we have no objective way to judge whether life is a onetime fluke or a near-inevitable phenomenon.
The moon is dark, and the gods dance in the night; there is terror in the sky, for upon the moon hath sunk an eclipse foretold in no books of men or of earth's gods.
It was only about sixty years ago that the expansion of the universe was first observed.
the moon rattles like a fragment of angry candy
An ordinary black hole is thought to be the end state of a really massive star's life.
