AN ANTI-UNIVERSE WHERE TIME RUNS BACKWARDS MAY EXIST NEXT TO OUR UNIVERSE

The theory involves the fact nature has fundamental symmetry and researchers think this could apply to the universe as a whole. It discusses a common physics concept called Charge, Parity, Time (CPT) symmetry. CPT symmetry is recognized as one of the laws of physics and means that CPT itself can be inverted after a transformative process. The belief was as such that there was a "backwards universe" before the Big Bang that was then inverted to create the universe we live in today. They are investigating the idea that the universe before the Big Bang is the CPT reflection of the universe after the bang, both classically and quantum mechanically. The universe before and after the bang may be viewed as a universe/anti- universe pair, emerging directly into the hot, radiation-dominated era we observe in our past. The wild theory could mean the presence of dark matter in the universe isn't so mysterious as thought. Scientists propose dark matter is actually a type of ghostly particle called right handed neutrino. Neutrino particles are present in the universe but they only spin to the left. Information about dark matter is slight other than it cannot be seen but does have a physical effect on other objects. Many believe neutrino particles and dark matter could potentially be a factor in proving the "anti-universe" theory. Scientists don't think we'd be able to visit the proposed anti-universe because it technically happened before the Big Bang.
