The most common image that comes from the Big Bang is that it is part of a surging point in a universe that is expanding.
Pero, pas qué pasa si èste universo es solo el gemelo de otro universo what form does the time take at this point and is it expanding in the current direction?
It is the intended audience that has recently made public a group of cosmologists from the Perimeter Institute of Physics in Canada.
An essay antiuniverso which, as it progresses in the opposite direction to the night, the time is changed correctly in the opposite direction.
This hypothesis, due to the fact that it does not exist, is an intention of all authors to explicitly specify the form and “economic“, various mysteries of the cosmos, among which the enigmatic matter of oscura.
Al otro lado del espejo
There are so many concepts to incorporate the idea of an anti-university.
The first one that comes with the Standard model of particle physicsthe theory that describes the fundamental particles of the universe that are the heavens and the forces that hac interact between them.
Seg eln el Módelo Estándar, if surge a particle of matter, surge también su counterpart of antimatteran identical particle with a cargo distance.
This is because what happened during the Big Bang produced the mass of matter and antimatter.
The second concept is the one symmetry.
In cosmology, it is an indicative principle that any physical process that does not include igual mantle is at the right time at the right time, if see space o si las particulas se reemplazan por antiparticulas.
Based on these principles, the analogy that hacierang is that if there is a universe, it is as if there is a symmetric antuniverse al que conocemos.
In a recent study by the Perimeter Institute of Physical Theory, the authors analyze a type of CPT lamp symmetry, initials, load, and time.
Esa symmetry indicates that it is invisible las cargas, the image and the time of a particle interaction, esa interaction se the misma manner.
Intonations, such as symmetry applied to the particles, are due to the fact that the authors of the study applied to the universe as a whole, thus obtaining the possibility of a symmetric universe.
“The universe in its conjunction is symmetric CPT”describe the authors in their investigation.
Be that as it may, the Big Bang is a point of departure from the origin of the universe and its imagen espejo.
“We suggest that the universe against the Big Bang is the ‘opposite’ of the universe deprived of the Big Bang,” say the authors.
¿How is this anti-university?
Latham Boyle, one of the co-authors of the studio, advised that no tiene certezas about the hypothesis of the anti-university and what its prophecies are about being tested experimentally.
Pero cree que su calculos le dan algunas pistas.
“At the moment, we believe that the opposite is a natural image reflected in time, with intercambiated parts and antiparticles “says Boyle in conversion with BBC Mundo.
Según esa visión, ese antiverso is not an independent universesino un mero reflejo de nuestro universo.
“We have an ‘anti yo’ in the other universe, but it is not independent,” says Boyle.
“If you decide to design a huevos, you have the opposite version and you can choose to design a tocineta.”
“If you want to get it, it tends to be bad antihuevos“.
¿What is the time in the opposite direction?
Seeking Boyle’s proposal and his colleagues, the Big Bang is like a speck that no solo invites the imagined image of time direction.
In ambos lados of the universe the time advance alejándose del Big Bangsolemnly that in a ladder the fleece of the time and the hacia the door, and in the other the hacia the izquierda.
“Everybody cares about the universe that is perfectly normal,” says Boyle. “Ambos creen que su timpo is advancing hacia adelante”.
“From our perspective, in the opposite the time advance hacia atráspero para ellos somos nosotros los que vamos al revés “.
This idea by Boyle includes other hallucinations: quizás seamos nosotros quienes estemos en el antiuniverso y no lo sepamos.
Do you think that quizzes are hacking: Is it possible to travel or be anti-university?
“We can not cruise the other side of the ladder,” says Boyle. “For this tendency to be positive viajar al pasado“.
It is said that it travels through space-time, cruising the Big Bang singles and salir al otro lado.
But most of all these ideas are about fiction, Boyle’s work, and his colleagues trying to find solutions to it. more practical problems of physics and cosmology.
It offers a clear vision of three fundamental concepts of cosmology: the oscillating matter, the inflation following the Big Bang and thewith gravitational waves
The oscurate matter is one mysterious ingredients which comprises 25% of the universe, even though it has not yet been observed which is or where it is.
The material oscurate, without embargo, if it can be swimmed by gravitational influence que ejerce sobre el cosmos.
Durant aisles, scientists have proposed various theories to explain what is oscillating matter, but nadie tiene una respuesta convincente.
Algunas of the respective respective constituents that the oscillating material is hecha of a particle that we do not know, is decis, which is due to the model á Standing.
Boyle’s studio, without embargo, offers a “more economical” replica of the enigmatic material.
It is intended to expose the oscurate material not necessarily imagining new particles.
In exchange, Boyle considers that the answer given is that the oscillating material is heck of “neutrinos diestros”a variety of neutrinos, the colors of which are part of the Standard Model.
Aún has not been tested that exists neutrinos diestros“, pero según Boyle, much more competing than what could be part of the Standard Model.
In this way, Boyle enjoys special exercise with new particles and concentrates in the layers of the physics that we know.
Hasta ahora, the neutrinos that are known as “zurdos”, with reference to the direction in which they are heavy.
In a symmetric universe, it is assumed that a neutral neutron is formed, that is, a antineutrinosee the astrophysicist Paul Sutter, in a portal article Live Science in which he researched Boyle’s studio.
These neutrino diestros serían mostly invisible y solo se podrían detectar su presencia a través de la gravedad.
“An invisible particle that encloses the universe and solo interaction traversed the engraved parece much to oscurate matter “explica Sutter.
Joseph Formaggio, a physicist who investigates the role of neutrinos in cosmology says that the interesting part of Boyle’s proposition to explain oscular matter.
“I like the model minimalists“, says the BBC World Cup, which is not involved in the investigation.
“Particularly in particle physics, many phenomena can be explained by introducing new particles, interactions and fields, together es fácil perderse“.
“Pero is currently under investigation, but not all of it has been observed,” concluded Formaggio, who heads the Division of Nuclear Experimental Physics and Particles at the Massachusetts Institute of Technology.
Formation refers to the idea of the neutral neutrons es muy comúneven though they do not exist.
“Son una particula nueva, en pero en realidad no lo son”, says between risas.
No inflation, no gravitational waves
Finally, the study questions the existence of cosmological inflation and primordial gravitational waves.
Boyle’s model asks that the Big Bang trace a period in what the universe it expands rapidlya concept conceived as inflation.
Esa inflation, a su vez, pudo haber creado unas primordial gravitational waveswhich have waves that travel through the space of time-spacing, such as waves that generate a foot launched in a slope.
Boyle’s prophecy that in the case of inflation, the matter of the universe expands in a very small way, without the need for a “epoch of inflammation”.
Entonces, según este modelo, si no hubo inflation, dampoco hubo ondas gravitacionales primordialles.
In 2015, gravitational waves were detected by the prime minister, Boyle, without embargo, advising that these correspond to posterior events in the Big Bang, but did not seem to have primordial gravitational waves.
