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.

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.
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.
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.
He sighed. "The clouds I can handle. But I can't fight with an eclipse.
An ordinary black hole is thought to be the end state of a really massive star's life.
It's a very typical UFO sighting. Carter said it changed color and, in the physical report, described it as being about the size of the moon. And he saw it with about twenty-five other people.
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.
