Tiger and Police in Time Loop
Oxford Railway Station is Where It's At
From Eternity to Here
A new book, From Eternity to Here: The quest for the ultimate theory of time, by Sean Carroll, suggests an eternal "mother space-time" producing a multiverse of baby universes some of which will have an initial entropy level that means time flows like it does in our universe. Craig Callender, a philosopher of science, who reviews the book in the 23rd January issue of New Scientist is not so sure. Sean Carroll meanwhile answers some readers' questions about time in that same New Scientist issue with more Q&As at www.newscientist.com/blogs/culturelab.

New Spiral Clock on the Market
Two entrepreneurs from Brixton, London, Will Aspinall and Neil Lambeth, have designed and are building and selling a fun spiral and ball clock. A bit pricey as yet but a fun 'twist' nevertheless on the regular clock. Links to short video clips are:

Photo of the Universe Furthest Back in Time
The Hubble Space Telescope has captured an image of the universe just 600 to 800 million years after the Big Bang.
The photo, which combines an August 2009 infrared image with an optical image taken in 2004, reveals galaxies never seen before.
The newly identified galaxies are invisible in the visible part of the light spectrum, but stand out clearly in the infrared images.
Scientists, who released the photo at a meeting of the American Astronomical Society on Tuesday, said the nearest galaxy in the image was an estimated one billion light years away.
The furthest - faint red specks seen in the image - were 13 billion light years away, meaning their light left them just 600 to 800 million years after the Big Bang.
The scientists said the photo was the most complete picture of the early universe so far and not only showed galaxies with stars that were already hundreds of millions of years old, but also the unmistakable primordial signs of the first cluster of stars.

All Change for Doctor Who and the Decade
So the turn of the decade sees the BBC's favourite Timelord, Doctor Who, morphing from David Tennant to Matt Smith. And the real 'Master', writer and producer Russell T Davies, finishes too. Tennant's final line, "I don't want to go", perhaps spoke for both of them, leaving Matt and new 'Master', Stephen Moffatt, much to live up to.
