When it comes to the science regarding the true nature of reality, you won’t find a shortage of theories, or a shortage of criticisms of each theory. We are like on a race with amnesia, trying to discover and search for an answer that most probably exists, but has yet to be discovered. How did the universe begin or what if the universe had no beginning?
The Big Bang is often considered the starting point of our universe, but two researchers have proposed an idea that does not point at Big Bang as the event that catapulted the formation of the cosmos.
According to new research, there might not have been a big bang. Instead, the universe might have existed forever. A quantum equation suggests that Big Bang never occurred and the universe has no beginning. The theory was derived from the mathematics of general relativity and a compliment to Einstein’s theory of general relativity.
The Big Bang singularity is the most serious problem of general relativity because the laws of physics appear to break down there, which predicts that the universe originated when an infinitely dense single point exploded outwards about 13.8 billion years ago.” – Ahmed Farag Ali, Benha University.
Which means that the cosmos did not have a beginning and does not have an end.
As far as we can see, since different points in the universe never actually converged in the past, it did not have a beginning. It lasted forever. It will also not have an end … In other words, there is no singularity,” says Professor Saurya Das of the University of Lethbridge, Canada.
This state, known as singularity, poses several problems for scientists because it did not take into account what happened before or at the moment of the Big Bang. By removing singularity, the model predicts that the universe does not have a beginning and has always exited in quantum potential before it collapsed into the Big Bang.
Brian Koberlein from the Rochester Institute of Technology pointed out that while it may appear that the study suggests that the Big Bang did not happen, the event still occurred.
Koberlein said that the researchers used the Raychaudhuri equation, which used some quantum tweaks. He also said that the idea of an eternal universe is not new.
The new model, which also considered dark matter and dark energy, also predicts a cosmological constant, an idea initially proposed by Einstein nearly 100 years ago, which posits that the universe is static instead of expanding.
We expect our main results to continue to hold even if and when a fully satisfactory theory of quantum gravity is formulated. For the cosmological constant problem at late times on the other hand, quantum gravity effects are practically absent and can be safely ignored,” the researchers wrote in a study published in the Physics Letter B on Jan.6.
