Increased the probability that our universe is a hologram

Can our universe be just a hologram? This idea is in the minds of the people before, and hardly anyone can be surprised, but nevertheless it seems so incredible, that people don't take it seriously. However, it may be a physical property of our world. And we may here see.

Mathematicians already familiar with the holographic principle, first proposed by renowned physicist Gerard t Goitom and developed the equally well-known physicist Leonard Susskind. He argues that, first, all information contained in some region of space, can be represented as a hologram — theory, which lives on the border of this region. Kind of dependent on the observer's gravitational horizon. Therefore, it requires one less dimension than it seems. More precisely, the theory on the boundaries shall contain a maximum of one degree of freedom at the Planck area. In a broader sense, since the universe seems to us to be three-dimensional, it can be actually a two-dimensional structure imposed on an incredibly large cosmic horizon.

In 1997 Juan Maldacena first postulated the theory of a holographic universe by saying that gravity arises from thin, vibrating strings that exist in ten dimensions. Since then, many physicists working in this direction.

"This work culminated in the last decade and suggests, curiously, that everything we experience is nothing more than a holographic projection of processes taking place on some distant surface that surrounds us, wrote physicist Brian Greene from Columbia University in 2011. — You can pinch yourself, and your feeling will be very real, but it mirrors a parallel process taking place to a different, distant reality."Physicists from the Vienna University of technology suggested that the holographic principle works even in flat space-time, not just in theoretical areas with negative curvature. As a rule, gravitational phenomena are described in three spatial dimensions, whereas quantum particles — only in two. It turns out, you can superimpose the results of one measurement to the other — and this striking conclusion has generated more than 10,000 scientific papers in theoretical physics on the topic of negatively curved spaces. However, until now it all seemed worth relatively far from our own, a flat, positively curved universe.

"If quantum gravity in flat space allows a holographic description of the standard quantum theory, then there must be a physical quantity that can be calculated in both theories and the results should be the same," says Daniel Grumiller the University of Vienna. This includes the manifestation of quantum entanglement in gravitational theory, that is, particles cannot be described individually. It turns out that you can measure the amount of entanglement in a quantum system, it is called entropy of entanglement. Grumiller shows that it has the same quantity in planar quantum gravity in two-dimensional field theory.The scientist noted that this compliance can be checked on the example of quantum entanglement, which manifests itself when object properties are initially interconnected, are correlated even when they explode at a distance: changing the properties of one object when a distance from the other from the system affects the properties of others.

"These calculations confirm our assumption that the holographic principle may take place in flat spaces. This evidence in favor of such compliance, and in our Universe, says Max riegler from the Vienna University of technology.Sounds incredible. However, another step in favor of the holographic Universe is frightening. published
