The Light Years: Elizabeth Jane Howard (Cazalet Chronicles)

Product Information

How much is that? The speed of light is 186,282 miles per second, or 299,792.5 kilometers per second. That's 670.6 million mph (170.9 million km/h). In comparison, the distance to the nearest star, Proxima Centauri is 4.2 light-years, or 24.7 trillion miles (39.8 trillion km). Measuring in miles or kilometers at an astronomical scale is impractical given the scale of figures being used. Starting in our cosmic neighborhood, the closest star-forming region to us, the Orion Nebula, is a short 7,861,000,000,000,000 miles away, or expressed in light-years, 1,300 light-years away. The center of our galaxy is about 27,000 light-years away. The nearest spiral galaxy to ours, the Andromeda galaxy, is 2.5 million light-years away. Some of the most distant galaxies we can see are billions of light-years from us. The galaxy GN-z11 is thought to be the farthest detectable galaxy from Earth at 13.4 billion light-years away.

Mars is around 1.5 AU from the Sun, and Jupiter is approximately 5.2 AU from the Sun. MOM WAS DEMANDING when it came to other people—and especially hard on the help. Our most recent nanny had been let go for body odor. Her room downstairs had been empty all summer while Mother tried to air out the smell of poverty.

This wonderful coincidence enables us to bring the light-year down to Earth. So, if we scale the astronomical unit– the Earth-sun distance – at one inch, then the light-year on this scale represents one mile (1.6 km). The distance to the next nearest star is millions of times larger than the distance between planets in the solar system . Although modern astronomers often prefer to use the parsec, light-years are also popularly used to gauge the expanses of interstellar and intergalactic space.

This stunningly beautiful, original memoir is driven by a search for the divine, a quest that leads Rush into some dangerous places . . . The Light Years is funny, harrowing, and deeply tender." —Kate Tuttle, The L.A.

Unlike the speed of a car, train or plane, the speed of which can change, the speed of light is constant and never changes. We know that through the vacuum of space, light travels at 670,616,629 mph (1,079,252,849 km/h). Generally speaking, there are 63,000 astronomical units in one light-year, and 63,360 inches (160,000 cm) in one mile (1.6 km).

The science and technology were described in simple, digestible terms for the readers without ever being "dumbed down" for the audience. The most complicated ideas in this book were the ones revolving around light speed travel and time relatively in space. As long as readers can grasp the basics of these concepts, they will be able to enjoy this novel. The nearest known star (other than the Sun), Proxima Centauri, is about 4.24 light-years away. [28] [29]One Julian year is exactly 365.25 days (or 31 557 600s based on a day of exactly 86 400 SI seconds) [4] As mythic and wild with love, possibility, and danger as the decades it spans, you’ll read The Light Years with your breath held. Brutal, buoyant and wise to the tender terror of growing up, Chris Rush has written a timeless memoir of boyhood in the American wilderness.” —Emma Cline, author of The Girls Both of Aden's and Hisako's lives are pretty mundane: playing music, enjoying various partners, dealing with home life and situations. It doesn't really make for much sci fi, the premise of which comes in at the last 20% or so. As well, because we are beaten over the head with the 'live and let live' themes, save the people, etc., it felt more like a manifesto wrapped in sci fi trappings. Adem was bland and unremarkable for a lead character and Hisako spends most of the time rebelling or wasting time. It was hard to see them as "the guy who knows the ship so well, he can fix anything" or the girl who was "gene spliced to be a near genius and can play 8 instruments." Instead, it was "I got screwed over because 2 years of my future were contracted" and "I probably should stop having sexual partners because I'm guilty about my upcoming marriage." Meanwhile, both spend most of the book playing instruments or talking about their life in a band or putting music vids up on the web. Not very sci fi.
