A team of Uppsala researchers may have solved the dark energy puzzle that might be constituting 95% of the universe. Their report, published in the journal ‘Physical Review Letters’, claims that the universe in which we live in a nook is actually an expanding bubble in an extra dimension. The Uppsala researchers created a new model with dark energy and our universe riding on an expanding bubble in an extra dimension, and the simulation revealed that our universe is accommodated somewhere on the edge of this bubble.

Uppsala researchers conducted this study based on the popular string theory, which has been to explain the universe’s accelerated expansion. String theory suggests that all kinds of matter consist of tiny vibrating string-like entities, and the new model used by Uppsala researchers suggests that existing matter in the universe corresponds to the ends of strings that extend out into the extra dimension.
“The new research report published by the Uppsala researchers may also provide different methods for scientists to test string theory. Recently, researchers at Oxford University have suggested that it is not the dark matter, but a dark fluid is constituting 95 percent of the universe,” reports IB Times.
