TEMPO.CO, Jakarta - Researchers from the Vanderbilt University in Nashville, Tennessee, United States of America, have discovered a mathematical formulation that supports dooms day theory Big Rip. The research, which is published in journal Physical Review D shows that the world will end in 22 billion years.
“The idea of the Big Rip is that eventually even the constituents of matter would start separating from each other. You’d be seeing all the atoms being ripped apart ... it’s fair to say that it’s a dramatic scenario,” said lead scientist Dr Marcelo Disconzi as quoted by Telegraph.co.uk on Friday, July 3.
Big Rip theory depends on assumption that the universe continues to grow faster and faster and finally causing Big Rip.
"Mathematically we know what this means. But what it actually means in physical terms is hard to fathom,” said Dr Disconzi.
The Vanderbilt researchers combined series of equations that shows viscosity may not be a barrier to a rapidly expanding universe. This answers questions previously raised over the Big Rip theory.
"What is known from current observational data is that a Big Rip scenario is possible, although the available data is far from conclusive. What our paper brings to the discussion is a mechanism that yields a Big Rip in a fairly natural way, in contrast of most models of the Big Rip where unnatural assumptions have to be introduced."
