She develops a cruel sense of humor, disappears from places unexpectedly, Lisa Shilling is an attractive, smart, and friendly girl from a comfortably middle class family in a small town in New York. She develops a cruel sense of humor, disappears from places unexpectedly, and even occasionally takes on an English accent and persona.
Almost all of us are. We think of ourselves, and the world immediately around us, as something special. And by extension we regard our kind of matter — atoms, molecules, rocks, water, air, stars and all of the other things that interact with visible light — as the most important kind of matter in the universe.
The only matter that matters, as it were. Science tells a starkly different story. The kind of matter that we can see makes up 4. Another fundamentally invisible type of matter vastly outweighs it, accounting for That means more than two-thirds of the universe has no substance at all.
Even the technical language used to describe the Planck result was humbling. But cosmologists have a hard time letting go of their prejudices. For years they convinced themselves that although the visible universe may be secondary in mass, it is where all the interesting things happen.
Extrapolating from their very limited knowledge of how dark matter works, cosmologists assumed that dark matter consisted of just one kind of substance with a limited range of behavior, tending to gather in giant, diffuse clouds.
They generally regarded dark matter as little more than the glue that holds together the visible universe and all its rich diversity. Two recent advances hint at just how much we have been missing about the dark side. In JanuaryChristoph Weniger, a physicist at the University of Amsterdam in the Netherlands, started noticing hints of a strange type of radiation around the center of our galaxy.
To his excitement, he realized that the glow could be a signal of dark-matter particles smashing into each other and, in the process, transforming from something invisible to something visible.
If so, it might finally be possible to go beyond simply deducing where dark matter gathers, and start learning how it actually behaves. The other shoe dropped earlier this year, when a group of Harvard University theorists, including Lisa Randall and JiJi Fan, formulated a new theory of dark matter.
But Randall and her collaborators realized they could tidily explain the observation if there were a second type of dark matter out there: Clumps of this interacting kind of dark matter could form a disk, collapsing into a plane that could produce a correspondingly concentrated signal like the one Weniger saw.
Acknowledging that dark matter might have some of the same kind of diversity as visible matter may seem a minor adjustment. It could ball up into dark stars surrounded by dark planets made of dark atoms.
In the most extravagant leap of possibility, this new kind of dark matter might even allow the existence of dark life.
We could be sitting right on top of a whole shadow galaxy and not even know it. Yet the tendency to judge the cosmos based on appearances and assumptions of our primacy has proved tenacious.
In the s, the iconoclastic Swiss-American astronomer Fritz Zwicky collected the first evidence for dunkle Materie — dark matter. It took another 40 years before his colleagues grudgingly began embracing the idea, persuaded by new evidence that rotating galaxies would fly apart without the stabilizing gravitational attraction of dark matter.
Not until the s did nearly all astronomers accept that dark matter is real, and that it substantially outweighs the visible cosmos.The book I reviewed is Lisa, Bright and Dark by John Neufeld. The book is a fiction/drama story and The theme is friendship.

Each participant completes a section of the image which is then assembled with the others to create a unique artwork. Escape from the city's bright glow. Dark Sky Finder helps you locate nearby dark skies to take a telescope, watch a meteor shower, or simply relax under the stars.
