‘Class A’, ‘Class B’, ‘Class C’, the acclaimed astrophysicist Avi Loeb published a column on the possible origin of the universe.
Acclaimed astronomer and former chair of Harvard’s Astronomy department, Abraham ‘Avi’ Loeb, suggested a new theory about the origin of the universe that has puzzled many. It all started with his column published in Scientific American suggesting that the universe could have been born in a laboratory belonging to an “advanced technological civilization.”
“Because our universe has a flat geometry with zero net energy, an advanced civilization could have developed a technology that created a baby universe out of nowhere through a quantum tunnel.”, The scientist published in his column.
a quantum tunnel it is an observable phenomenon in the microscopic world: it happens when particles can sometimes pass through walls or barriers and access places that should be out of their reach, even though they do not have enough energy to do so. That would be the way in which the created universe could manifest itself in reality.
The astronomer believes that in the universe there could be different types and levels of civilizations, and the scientific level that the Earth has is to be located in ‘Class C’, which would result in a dependence on the host star, the Sun.
There are conditions: “If the technology of the planet advanced to the point of not depending on the Sun, it would become part of class B; and if small universes are created in a laboratory, the planet would be included in class A ”.
According to Loeb’s conception, this ‘Class A’ civilization it would have managed to unify the idea of a creator, typical of religions, with the scientific notions inherent to quantum gravity. Consequently, it would dominate the keys to create a universe from scratch, within the framework of a biological system that would be based on the accumulation of intergenerational genetic information, thus promoting the evolution of civilizations.
However, there are several factors to take into account and the difficulties that humanity would face with this, among them the inability to develop “a sufficiently large density of dark energy within a small region.” Therefore, Loeb argues that if this is achieved, there could be a union with the eventual creators of class A.
If this theory is correct, humanity should step down from the pedestal that positions it as a “chosen civilization” to manifest the miracle of life in the universe: on the contrary, it would be just one more link in an intergenerational chain through which multiple civilizations advance, until they can recreate and reproduce the characteristics of the universe that contains them.
The astronomical sector cannot go unnoticed the opinion of the expert. Loeb was chairman for nine years of the Department of Astronomy at Harvard University, founding director of the Harvard Black Hole Initiative, and director of the Institute for Theory and Computing at the Harvard-Smithsonian Center for Astrophysics. In addition, he is currently a member of the Council of Science and Technology Advisors to the President of the United States. (I)
