The new scenario of Doomsday revealed

Scientists have had a consensus about the beginning of the universe, namely through the Big Bang 13.8 billion years ago. However, about the end of time, until today, scientists are still groping.

Recent theoretical modeling conducted by Marcelo D Disconzi of the Department of Mathematics, Vanderbilt University, Nashville, USA, revealed that the universe is likely to end up passing the Big Rip scenarios.
The end of the world (and indeed the universe) as we know it won’t be an explosion but a separation of the constituents of all matter, say scientists at Vanderbilt University. (Picture from: http://bit.ly/1dCYkae)
"The idea of ​​a Big Rip basically is that in the end, will be an integral constituent material. You will see the atom torn. It could be said that the dramatic scenario," said Disconzi.

There are "hidden forces" in the universe, among them the gravity and dark matter. The existence of dark matter, so called because even to this day has not been found to exist, making the universe expands.

Evidence of expansion of the universe is the result of the supernova observations that were located far from Earth. The more distant supernova, the more color is red because the light has been refracted wading along its journey through space and time toward the human.

"You've got competition between dark matter that are trying to develop the universe and gravity which tends to compress them. The question is, who wins?" Disconzi said as quoted by The Guardian on Thursday, July 2, 2015.

When gravity is winning, what happens is the Big Crunch. Initially, the universe will expand. However, due to the influence of gravity, the universe will be compressed until at one point very compressible, allowing the Big Bang event will coming back.

If dark matter wins, the Big Freeze will be happen. In that scenario, the universe will continue expanding until at one point a very tenuous and gas is too thin to be able to produce stars. In the end, no matter what happens.

In research published in the Physical Review D journal, Disconzi modeling by entering the fluid viscosity factor and the ability to expand and condenses. In this case, the fluid is the universe itself.

Fluid viscosity actually has been included in the calculations to uncover the end-time scenarios. However, in the calculation of the time, otherwise there is a fluid which is able to move faster than light.

"This is a fatal error because it was evident that nothing can travel faster than the speed of light," said Disconzi. With that revision, dark matter might be a winner, but will not make the universe is the Big Freeze. *** [EKA | FROM VARIOUS SOURCES | THE GUARDIAN]
