“Chirality” has a reversal, (the term chiral means that an object cannot coincide with its image). Like our hands, the left hand and the right hand mirroring each other do not coincide. This means that objects that appear in our reality (the universe) will become left-handed.
Entropy is also reversed, which means that for people living on the other side of the universe, time seems to be the opposite of our own. If we look directly at the interpretation of the universe by general relativity, we will understand that the big bang is not the beginning of everything. One of the most important mysteries that humans want to understand is to understand what happened before the birth of time and space. We have always believed that the Big Bang theory is the beginning of our universe.
