A new estimate shows that the universe may include about 6 * 10 ^ 80 — or 600 million megamone -information bit.
These findings may suggest that the universe is actually a huge computer simulation (form).
This incredible number is even a more strange assumption behind it. 60 years ago, Rolf Landauer, a German physicist, proposed the equivalent between information and energy, because the digital bit in the computer will generate a small amount of calories -a form of energy.
Because Einstein's famous Formula E = MC^2 indicates that energy and material are different forms of each other, Melvin VOPSON, a physicist at the University of Puzmouth, the University of British Planting relationships.
"Using quality-energy-information equivalent principles, I speculate that information may be the main form of material in the universe." He told astronomical online. Information can even explain dark matter, a mysterious substance that constitutes the vast majority of substances in the universe. He added.
VOPSON began to determine the amount of information in a single secondary particle (such as protons or neutrons). He said that such entities can be described with three basic features: their quality, charge and rotation.
"These properties make basic particles distinguish with each other and be regarded as 'information'." He added.
The information has a clear definition. It is first proposed by American mathematician and engineer Claude Shannon in 1948. By observing the maximum efficiency of information transmission, he introduced the concept of Bit, and also mentioned that this value can be 0 or 1 and is used to measure the information unit. This is like measuring distance with feet or meters, or uses the temperature to measure the temperature.
Using Shannon's equation, VOPSON calculates that a proton or neutron should contain an equivalent of 1.509 bit encoding information. After that, in order to determine the total information content of the universe, VOPSON speculates that the estimated value of the total number of particles in the universe -about 10 ^ 80, which is consistent with the previous estimation. His discovery was published on the magazine AIP Advances on October 19.
Even if the number obtained is huge, it is still not enough to explain the dark matter in the universe, VOPSON said. In his earlier work, he estimated that about 10 ^ 93 bit information -this number was 10 trillion times that he got -to do this.
"The number I calculates is smaller than I expected," he said, and added that he didn't know why. It may be because some important things have not been able to explain his calculations. These are only concerned about particles such as proton and neutrons and ignore the calculation of entities such as electron, neutrinos and quarks. According to VOPSON, only protons and mediums Only can they store their own information.
He admits that this assumption may be wrong, maybe other particles can also store their own information.
Greg Laughlin, a astronomer at Yale University, said that this may explain why his results are so different from the calculation results of the previous universe -the previous calculation results are higher. He himself did not participate in the study.
"This is not to ignore the elephant in the room, but to ignore the 10 billion elephant in the room." Laughlin told astronomy online. This refers to many particles that are not considered in the new estimation.
Laughlin said that although this calculation was not applied immediately, in fact, they may be useful for those who speculate that the universe is actually a huge computer simulation, and this so -called simulation false saying is "a great idea" Essence
"Calculating information content -Basically, the number of memory places needed to run the universe -very interesting." He added.
However, so far, the simulation assumptions are still only one assumption. "No way to know if this is true." Laughlin said.

The universe is the uniform of all time, space and the contents it contains; it contains planets, stars, galaxies, galaxy inter -system spaces, secondary particles, and all material and energy. At present, the universe that human beings can observe is about 93 × 10 ⁹ light years, and the maximum is 27,160 million seconds gap; the size of the entire universe may be infinite, but there is no conclusion.
