What is a big reflection?
A great reflection is the name of the scientific theory of the origin of the universe. Theory is to replace the earlier theory known as the Big Bang. The Big Bang is not in line with some aspects of general relativity, Einstein's famous theories that explain how matter and energy interact. According to the theory of Big Bang, the universe originally spread from a small static point for reasons that have not yet been understood. According to Big Bounce, the current universe resulted in the collapse of the previous universe.
From prehistoric times, people thought about the origin of the country and its surrounding universe. Religion, philosophy and early science were theories about how the universe began with an increasing level of sophistication. Astronomical observations in the 20th century confirmed that the universe has been expanding for billions of years. Physicists who worked backwards suggested that the universe starts as a small, dense area that contains all the energy and energy. The inexplicable event 14 billion years ago caused this matter and energy to expand the event called VelKý Bang.
The problem with this theory is that it does not explain what existed before the Big Bang or what caused expansion. These matters were described as singularity, an area of the universe in which physical laws do not apply. This was the only way to harmonize the big bang with the theory of the general relativity of Albert Einstein, the best model of how the universe works. Scientists also considered an alternative explanation of how the universe began. In the first decade of the 21st century, the theory of great reflection resulted.
According to the theory of Big Bounce, when the universe expands at a certain point, gravity causes to collapse again, the so -called great crisis. Once a tsbing universe reaches a certain density, a principle called quantum gravity loop causes the matter and energy to "bounce", or again expand and create a new universe. Big Bounce theory does not reveal whether this has happened once or many times; could be repeated nEkoněl. Another interesting option is that these infinitely recurring universes are identical and effectively create a universal time loop.
The Big Bounce theory is attractive to many physicists because it does not include singularity and because it involves general relativity and quantum mechanics, two principles of physics that are notoriously difficult to reconcile. Another study is required to determine which theory really describes the origin of the universe. It depends a lot on the quantification of dark matter and dark energy, mysterious substances that can affect the degree of expansion of the universe. Meanwhile, this theory has already provided material for science writers. In the episode of the animated comedy from 2011 futurama , the main characters watched a big reflection as they traveled to the far future.
