Bringing Space And Time Together, Study Examines Universal Symmetry
Evolution has been examined through numerous theories and facts and it has also sparked many debates on how organisms evolved throughout Earth's history. In the latest study, Joan Vaccaro from Griffith University examined space and time collaboratively, where she challenged some of the long-held views on time and evolution of the universe. Vaccaro found that the "incessant unfolding of the universe over time is an elemental part of Nature." The asymmetry between space and time may have a deeper origin, which is the two different directions of time, the future and the past.
"If you want to know where the universe came from and where it's going, you need to know about time," Vaccaro, said in a news release. "Experiments on subatomic particles over the past 50 years ago show that Nature doesn't treat both directions of time equally. In particular, subatomic particles called K and B mesons behave slightly differently depending on the direction of time."
Vaccaro claimed that this subtle behavior is a result from changes in the universe that goes from being fixed at one moment to persistently evolving. This subtle behavior is responsible for driving the universe into the future.
"Understanding how time evolution comes about in this way opens up a whole new view on the fundamental nature of time itself. It may even help us to better understand bizarre ideas such as travelling back in time," said Vaccaro.
The asymmetry that exists between time and space indicates that these physical systems evolve of time. Vaccaro claimed that this elemental asymmetry is shown with equations of motion and conservation laws, which changes with time and space. Vaccaro used a "sum-over-paths formalism" to examine the time and space symmetry.
"Yet while we are indeed moving forward in time, there is also always some movement backwards, a kind of jiggling effect, and it is this movement I want to measure using these K and B mesons," Vaccaro said.
The findings of this study were published in the Proceedings of the Royal Society A.
