First evidence of other universes that exist alongside our own after scientists spot 'cosmic bruises'

The different signatures of a bubble collision. A collision (top left) induces a temperature change in the CMB temperature map (top right). The 'blob' associated with the collision is identified by a large needlet response (bottom left), and the presence of an edge is determined by a large response from the edge detection algorithm (bottom right)

Scientists say that they have found evidence that our universe was 'jostled' by other parallel universes in the distant past.
The incredible claim emerged after they studied patterns in the cosmic microwave background radiation (CMB) – the after-effects of the Big Bang.
They say they may have found evidence that four circular patterns found in the CMB are 'cosmic bruises' where our universe has crashed into other universes at least four times.


Massive dark object 'lurking on edge of solar system hurling comets at Earth'

Friday, December 10, 2010

A massive dark object may be lurking on the edge of our solar system, according to scientists.
Most comets that fly into the inner solar system seem to come from the outer region of the Oort cloud - a region of icy dust and debris left over from the birth of the solar system.
The cloud starts from a point about 93 billion miles from the Sun and stretches for around three light years and contains billions of comets, most of them small and hidden.

Now new calculations suggest a large object that is up to four times as big as Jupiter could be responsible for sending them in our direction.
The scientists have analysed the comets in the Oort cloud and deduced that 25 per-cent of them would need a nudge by a body of at least Jupiter size before they changed orbit.
