"Dark matter, which researchers believe make up about 80% of the universe's mass, is one of the most elusive mysteries in modern physics. What exactly it is and how it came to be is a mystery, but a new Johns Hopkins University study now suggests that dark matter may have existed before the Big Bang.

The study, published August 7 in Physical Review Letters, presents a new idea of how dark matter was born and how to identify it with astronomical observations.

"The study revealed a new connection between particle physics and astronomy. If dark matter consists of new particles that were born before the Big Bang, they affect the way galaxies are distributed in the sky in a unique way. This connection may be used to reveal their identity and make conclusions about the times before the Big Bang too," says Tommi Tenkanen, a postdoctoral fellow in Physics and Astronomy at the Johns Hopkins University and the study's author.

For a long time, researchers believed that dark matter must be a leftover substance from the Big Bang. Researchers have long sought this kind of dark matter, but so far all experimental searches have been unsuccessful.

"If dark matter were truly a remnant of the Big Bang, then in many cases researchers should have seen a direct signal of dark matter in different particle physics experiments already," says Tenkanen.

Using a new, simple mathematical framework, the study shows that dark matter may have been produced before the Big Bang during an era known as the cosmic inflation when space was expanding very rapidly. The rapid expansion is believed to lead to copious production of certain types of particles called scalars. So far, only one scalar particle has been discovered, the famous Higgs boson.

"We do not know what dark matter is, but if it has anything to do with any scalar particles, it may be older than the Big Bang. With the proposed mathematical scenario, we don't have to assume new types of interactions between visible and dark matter beyond gravity, which we already know is there," explains Tenkanen.

While the idea that dark matter existed before the Big Bang is not new, other theorists have not been able to come up with calculations that support the idea. The new study shows that researchers have always overlooked the simplest possible mathematical scenario for dark matter's origins, he says.

The new study also suggests a way to test the origin of dark matter by observing the signatures dark matter leaves on the distribution of matter in the universe.

"While this type of dark matter is too elusive to be found in particle experiments, it can reveal its presence in astronomical observations. We will soon learn more about the origin of dark matter when the Euclid satellite is launched in 2022. It's going to be very exciting to see what it will reveal about dark matter and if its findings can be used to peak into the times before the Big Bang."

Määritelmällisesti käsitettä big bang käytetään vain niin, että aika kuten avaruuskin laajenee siitä. "Before big bang" on mieletön ilmaus.

Määritelmällisesti käsitettä big bang käytetään vain niin, että aika kuten avaruuskin laajenee siitä. "Before big bang" on mieletön ilmaus.

Tähän alkuun naurava kulkuri kikattamaan, hehehehehehehehe.

Energiansäilymislaki laittaa teidät ruotuun alkuinenne.  Pimeä materia on ollut ennen BB:tä, tietysti on.

BB on vain ja ainostaan TÄMÄN universumin alku, niitä on näet muitakin, ihan helvetisti onkin.

Minun mielestä noin.

Itse tutkimuspaperissa käytetään käsitettä "pre-big bang peoch". Toimittajat lienevät lukeneet tuon "pre- big bang", kun kuuluisi lukea "pre-big".

Ideahan tuossa on juuri se, että pimeää ainetta olisi muodostunut ihan ekaksi ja sitten vasta / siitä johtuen inflaatio ja raju tilan laajentuminen.

Mikäli oma ideani massajakaumamuutosten infirmaatiosignaaleihin varastoituneesta gravitoivasta massaenergiasta pimeän massan selittäjänä kestää falsifioinnin, tämän tutkielman periaatteet ovat hyödyllisiä testaukseen.

Eiköhän ne kphta korjaa ylopiston suunnalta määritelmävirheensä.

Tämä Tenkanen näyttää kuitenkin olevan käsitehämmentäjä ja oikeastaan BB:n vastustaja tällä hypoteesillaan.

Jos mallissa ei ole mitään alkua, luulisi käyttävän muuta kuin big bang -terminologiaa.

Onhan siinä sisällöllisesti ihan avaraa pohdintaa.

Kun tarkastellaan informaation ja gravitaation yhteyttä, ainerakenteen rakenneinformaatio on tilan kannalta ilmeinen nielu. Sen sijaan laajemmat galaksirakenteet ajatellaan yksioikoisesti seuraavan ainesten liikkeistä ilman informaatiota tai ei ainakaan huomata informaatiotarpeen ja gravitaation yhteyttä.

Massajakauman ja erityisesti sen muutoksen informaatio on määrältään hyvin merkittävää, vaikkakin jakautunut laajalle, eikä sitä voi paikallisesti mitata - siis ei pimeän aineen hiukkasta.

Näen, että informaation ja inertian/gravitaation ekvivalenssista voimme löytää pimeän massan ja toki myös pimeän energian, koska siellä missä informaatiota ei ole aineen järjestykseen liittyen siellä on kerääntynyttä avaruudenluonteista aaltokvanttia laajentamassa tilaa - kiihtyvästi, jos mittaajan ympäristössä on astronomisesti lähellä merkittävää tyhjää kuplaa, meillä on.

Kaikella kunnioituksella jussipussi. Ei näy. Tässä on taas se toimittajien (tietämätön) väärinkäsitys siitä mitä tarkoittaa (laskennallinen) BB ja mitä HBB. Tenkanen puhuu nimenomaan inflaation aikuisesta (mahdollisesta) pimeän aineen synnystä ENNEN varsinaisten alkeishiukkasten syntyä ( eli inflatonikentän purkua alkeishiukkasiksi = on meidän HBB).

Tässä nimenomaan toimittajat eivät tiedä mitä tarkoittavat inflaatio, BB ja HBB (ja sekoittavat asiat herttisen sulokkaasti).

Eli Eusa on oikeassa.
