Cutting-edge astrophysics that builds on Einstein's theories tofind the unseen matter that fills the Universe.

Dark energy. Dark matter. These strange and invisible substancesdon't just sound mysterious: their unexpected appearance in thecosmic census is upending long-held notions about the nature of theUniverse. Astronomers have long known that the Universe isexpanding, but everything they could see indicated that gravityshould be slowing this spread. Instead, it appears that theUniverse is accelerating its expansion and that something strongerthan gravity --dark energy -- is at work. In Einstein'sTelescope Evalyn Gates, a University of Chicago astrophysicist,transports us to the edge of contemporary science to explore therevolutionary tool that unlocks the secrets of theselittle-understood cosmic constituents. Based on Einstein's theoryof general relativity, gravitational lensing, or "Einstein'sTelescope," is enabling new discoveries that are taking us towardthe next revolution in scientific thinking -- one that may changeforever our notions of where the Universe came from and where it isgoing.

Opinion

From Library Staff

Astrophysicist Evalyn Gates explains everything about the cosmos, dark matter, and this little thing called gravity. Sheldon Cooper undoubtedly taught her everything she knows.

There is no doubt about it, we need more copies of this book! It displays a very compelling hyspothesis, supported by logical arguments and evidence. As a 14 year old intrested in this subject, let me speak on behalf of all other teenagers when I say that we need more novels like this in public libraries. This is what will engage the next generation of theoretical physicists. Thank you for attending my TED talk.

The author does a good job of explaining logically how known astronomical observations lead to a requirement for dark matter and what it might be like. A compelling argument for the existence of dark matter. I didn't find her arguments for dark energy as convincing.

Lots of good technical information. A bit dry in that there was little discussion of the personalities of the people involved. For example, in the last chapter, she glossed over the field of gravity waves without discussing a lot of controversy plus a long series of negative results.

"Einsteins Telescope" is excellent! Gates explains how we know dark matter and dark energy exist, and what we are doing to understand their mysterious nature. This was a very entertaining book, filled with a lot of good information. I would recommend this to anyone interested in modern cosmology, especially those who want to know more about dark matter and dark energy.

A very convincing set of arguments in favour of the Dark Matter hypothesis that explains why there must be a lot more matter in the universe than we can see.

I dipped into this book at about a dozen or more different points, about a dozen times over a weekend, and always found it exciting ... and perplexing. I intend to dive back into the book and read it straight through puzzling out the implications, and the math (so far as I am able!) in the very near future.
Gates is a fluent and subtly funny writer (as a woman in a field massively over-dominated by men she would have to have a sense of humour, eh?) Well worth the effort.
A delightful hour long video of Gates covering the material in her book can be seen at: http://www.pdxjustice.org/node/54
