Our Universe May Exist in a Multiverse, Cosmic Inflation Discovery Suggests

The first direct evidence of cosmic inflation — a period of rapid expansion that occurred a fraction of a second after the Big Bang — also supports the idea that our universe is just one of many out there, some researchers say.
On Monday (March 17), scientists announced new findings that mark the first-ever direct evidence of primordial gravitational waves — ripples in space-time created just after the universe began. If the results are confirmed, they would provide smoking-gun evidence that space-time expanded at many times the speed of light just after the Big Bang 13.8 billion years ago.
The new research also lends credence to the idea of a multiverse. This theory posits that, when the universe grew exponentially in the first tiny fraction of a second after the Big Bang, some parts of space-time expanded more quickly than others. This could have created “bubbles” of space-time that then developed into other universes. The known universe has its own laws of physics, while other universes could have different laws, according to the multiverse concept.

A sensational breakthrough: the first bionic hand that can feel
The first bionic hand that allows an amputee to feel what they are touching will be transplanted later this year in a pioneering operation that could introduce a new generation of artificial limbs with sensory perception.
The patient is an unnamed man in his 20s living in Rome who lost the lower part of his arm following an accident, said Silvestro Micera of the Ecole Polytechnique Federale de Lausanne in Switzerland.
The wiring of his new bionic hand will be connected to the patient’s nervous system with the hope that the man will be able to control the movements of the hand as well as receiving touch signals from the hand’s skin sensors.
Dr Micera said that the hand will be attached directly to the patient’s nervous system via electrodes clipped onto two of the arm’s main nerves, the median and the ulnar nerves.
This should allow the man to control the hand by his thoughts, as well as receiving sensory signals to his brain from the hand’s sensors. It will effectively provide a fast, bidirectional flow of information between the man’s nervous system and the prosthetic hand.
“This is real progress, real hope for amputees. It will be the first prosthetic that will provide real-time sensory feedback for grasping,” Dr Micera said.
“It is clear that the more sensory feeling an amputee has, the more likely you will get full acceptance of that limb,” he told the American Association for the Advancement of Science meeting in Boston.
“We could be on the cusp of providing new and more effective clinical solutions to amputees in the next year,” he said.

DO YOU PEOPLE EVEN REALIZE HOW AWESOME THIS IS???
TO DO THIS MEANS WE CAN FINALLY STICHT AXONS (LONG PART OF NEURON OR NERVE CELL THAT TRANSPORTS SIGNALS FROM JUNCTIONS BACK TO THE BRAIN) BACK TOGETHER
DO YOU EVEN UNDERSTAND HOW IMPOSSIBLE THAT WAS? TO ALINE THE DAMAGED AXONS BACK TOGETHER WAS IMPOSSIBLE 
WITH THIS BRAKE THROUGH YOU COULD EVENTUALLY WORK UP TO GIVING THE ABILITY TO WALK AND MOVE AGAIN TO THOSE WHO CUT THEIR SPINAL CORD IN AN ACCIDENT THIS IS BEAUTIFUL
THIS. IS. AMAZING.

this is so fantastic that I am at a complete loss
bionic body parts that function and feel and act just like real body parts are the first step toward the actual cyber future

It was discovered by William Herschel on September 9, 1798. NGC 6946 is highly obscured by interstellar matter of the Milky Way galaxy, as it is quite close to the galactic plane.

As a New Zealander I thought it was high time I posted some archaeology a bit closer to home.

A very important Pacific archaeological site located on the south eastern coast of Raiatea, French Polynesia -the Taputapuatea Marae.

For those of you who don’t know, a marae is a sacred religious gathering place in Polynesian societies. This particular marae was already established by 1000 AD, and was once known as the religious centre and central temple of Eastern Polynesia. Here, people such as priests and navigators would meet to share knowledge and preform sacrifices to the gods.

Member of the Moari iwi Te Rangi Hīroa (anthropologist, politician), upon visiting the site in 1929 was overcome with grief due to the state of the once great marae, and consequently wrote:

I had made my pilgrimage to Taputapu-atea, but the dead could not speak to me. It was sad to the verge of tears. I felt a profound regret, a regret for — I knew not what. Was it for the beating of the temple drums or the shouting of the populace as the king was raised on high? Was it for the human sacrifices of olden times? It was for none of these individually but for something at the back of them all, some living spirit and divine courage that existed in ancient times of which Taputapu-atea was a mute symbol. It was something that we Polynesians have lost and cannot find, something that we yearn for and cannot recreate. The background in which that spirit was engendered has changed beyond recovery. The bleak wind of oblivion had swept over Opoa. Foreign weeds grew over the untended courtyard, and stones had fallen from the sacred altar of Taputapu-atea. The gods had long ago departed.

(ref: D. Hanlon, Voyaging Through the Contemporary Pacific)

Fortunately, as of 1994, the archaeological remains of Taputapuatea has been restored, and is currently being pushed to become a recognized United Nations World Heritage site.
