At 13.7 billion years old, the universe is inconceivably ancient. As new stars are born every day, its cosmic inhabitants are constantly changing, but scientists have now discovered the oldest star existing in space.

The old timer was identified by a team of astronomers from The Australian National University, who believe it formed shortly after the" Big Bang" that spawned the cosmos 13.7 billion years ago.

The newly-observed star, christened SMSS J031300.36-670839.3,has just topped the age of the current record holder, HD 140283 or "The Methuselah Star," which has been dated to be 13.2 billion years old.

The romantic notion of "stardust" has inspired authors, poets and song-writers for decades, leading to a dictionary definition that describes it as "a magical or charismatic quality or feeling."

Despite its enchanting reputation, this seemingly mystical substance is not merely confined to the imagination but is a genuine scientific term for the tiny cosmic dust grains floating through our solar system.
When Moby claimed in his 2002 song that "We Are All Made Of Stars," however, he may not have been too far from the truth, as scientific evaluations of this space dust over the past few years have yielded the surprising evidence that every atom in our bodies was once part of a star, maybe even several stars.

A team of scientists from Washington believe that they have managed to establish the exact size of the universe to within 1 per cent accuracy.

In a remarkable development, the researchers, who were working with the Baryon Oscillation Spectroscopic Survey (BOSS), have been able to measure the distances to galaxies that are over 6 billion light years away.

"There are not many things in our daily lives that we know to 1-percent accuracy," said David Schlegel, a physicist at Lawrence Berkeley National Laboratory and the principal investigator of BOSS. "I now know the size of the universe better than I know the size of my house."

Scientists have discovered that the universe is made up of plus and minus bits, just like a computer program. So, is the Matrix real? Do we actually exist as living, conscious entities or are we part of somebody’s experiment…or perhaps even a toy?

The field of quantum chromodynamics potentially offers this unsettling explanation for the fundamental construction of the Universe. Scientists have tested this theory with some success, though the degree of complexity involved means that only the world’s most powerful super-computers are up to the job. In doing so, however, they came to the realization that simulating physics at this level was essentially the same as simulating the Universe itself.
