Imagine that you regain consciousness after your death and start life as an old or old woman, becoming everything with time younger. At some point you get a job, and after go to university. When you go to school, then others it becomes clear that you will soon be gone. Kindergarten, nursery … Turning into a newborn baby, you soon stop exist. This is exactly what life in parallel can be. The universe.
Can the universe consist of antimatter?
A group of physicists conducted a study and came to the conclusion that our The universe may have a “twin” where time flows back. Of course, while this is a pure theory, however, it answers some important issues that science has been struggling with for a long time. One of it sounds like this: if during the Big Bang The universe was derived from equal parts of matter and antimatter, then where in this case is all the antimatter?

The English theoretical physicist Paul Dirac was the first to suggest the existence of antimatter in 1928. After that, scientists found a wide range of antiparticles. They meet during high-energy collisions in other parts of the universe as well also during operation of charged particle accelerators. Most such an accelerator is the Large Hadron Collider, Built near Geneva by the European Nuclear Council research.
In 1964, an experiment took place that brought 16 years later its authors the Nobel Prize. Americans James Cronin and Val Fitch supposedly proved that the universe consisting of antimatter is not may exist for the simple reason that a weak nuclear force violates this model. And for several decades it was perceived, as a fact. However, in 2004, American cosmologist Sean Carroll and his graduate student Jennifer Chen decide to revise the theory “mirror” of the Universe, answering a burning question Science: Does time flow only in one direction?
Does time flow only in one direction?
In the course of their research, Carroll and Chen created a complex model. The Big Bang, which “shoots” simultaneously in two opposite sides. Thus two Universes are created. One of them, ours, is composed of matter, and the other is of antimatter. While in one universe, time moves forward, in a second it flows back. However, for the inhabitants of that, another, our Universe time, as you might guess, is tantamount to reversing.

In general, when we talk about time, we consider the second the law of thermodynamics, especially entropy. It’s about quantity disorder in the system, which ultimately disables it. Such a system can be any mechanism, computer, star or human body. Entropy grows exponentially, while it’s too early or late does not absorb the entire system. However, instead of entropy Carroll and Chen decided to focus on gravity.
By examining a thousand particles and applying Newtonian physics, scientists managed to prove that the existence of a double universe is hypothetically perhaps. Their model even takes into account weak nuclear strength. Now now another group of researchers decided to delve deeper into this question. This team consists of Briton Julian Barbour, as well as Canadians Tim Kozlowski and Flavio Mercati. They studied a similar autonomous system of a thousand particles, basing its research more on gravity than thermodynamics.

The model showed gravity expanding in two directions. Scientists called it Janus Point in honor of the two-faced god from ancient Roman mythology. So, in our universe, entropy is that time moves forward. In physics, this is called axis of time. Experts report that if you consider time as natural phenomenon, and not as a given force, then it can flow simultaneously in two opposite directions. As a result this creature from a parallel universe is probably very similar to us, but the difference in the direction of the passage of time makes them existence radically different from ours.
Is it possible to look into a parallel universe?
Unfortunately, even if such a parallel universe and exists, we are unlikely to ever be able to look into it, like its inhabitants are to us. Two realities flow from a central point and cannot interact with each other in any way. That is, cross Janus point is not possible, as this would contradict fundamental laws of physics.

However, to say anything with absolute accuracy, people of science still not solved. Maybe these laws are not so fundamental, and the man didn’t actually discover, but invented them, but actually in Multiverse anything is possible.
