“I believe the Big Bang never happened,” said Juliano César Silva Neves, a physicist at the University of Campinas’s Mathematics, Statistics & Scientific Computation Institute (IMECC-UNICAMP) in Sao Paulo State, Brazil.
Although for five decades, the Big Bang theory has been the best known and most accepted explanation for the beginning and evolution of the Universe, it is hardly a consensus among scientists, according to Neves, part of a group of researchers who dare to imagine a different origin., said agency FAPESP.
Sputnik Russian news agency (formerly Voice of Russia and RIA Novosti) printed in its site (on Sunday, Dec.3) a theory of Brazilian physicist Juliano Cesar Silva Nunes (University of Campinas, in São Paulo) has come up with a new “cyclical” theory, which challenges this prevailing concepto of the Bing Bang.
Silva Nunes has proposed a way of overcoming the problem presented by the Big Bang theory, the need for the singularity of spacetime, by doing away with the theory altogether.
In an article entitled, “Bouncing cosmology inspired by regular black holes,” publishedi n the September issue of the General Relativity and Gravitation journal, Neves puts forward the notion that the universe expands and contracts in a cyclical way. “One of the consequences of my work could be a ‘cyclical’ vision of the universe,” Silva Neves, told Sputnik Brail.
“My proposed cosmological model, of course, acknowledges the expansion of the universe and also other known phenomena such as cosmic radiation. For me, the main issue is the Big Bang and the state of initial singularity. That is, the [theorized] first stage of the universe’s existence, a state in which the physical and geometric quantities that figure in Einstein’s theory of relativity, do not have a set value.”
“In the words of mathematicians, these quantities tend toward infinity. This can be perceived as a problem with the theory of relativity, and most of the scientific community thinks that in the future this can be solved with the help of a theory of quantum gravity, which does not yet exist,” Neves explained.
