At LiveScience: Dark matter could morph into ordinary matter via “gravity portals”

According to astrophysicists:

Astrophysicists have an idea that could help to solve two mysteries: the reason for the bizarre abundance of super-high-energy radiation shooting from the center of our galaxy and the identity of invisible stuff called dark matter that has perplexed the world since its discovery some 50 years ago.

And the idea has a super-cool name: gravity portals. The idea goes, when two dark matter particles (whatever they are) get sucked into one of these portals, they obliterate each other and spit out shockingly strong gamma rays.

This line of thinking can potentially explain why the galactic center — where dense clusters of dark matter are thought to lurk — is full of gamma rays; and it could shed light on how the dark matter behaves and might occasionally interact with the normal matter of our universe.

Finding a single particle of dark matter would be a way better explain than any of the theories we’ve heard so far.

Researcher: The search for dark matter has become a “quagmire of confirmation bias” So many research areas in science today are hitting hard barriers that it is reasonable to think that we are missing something.

Proposed dark matter solution: “Gravity is not a fundamental governance of our universe, but a reaction to the makeup of a given environment.”

    True, but we need theories of what dark matter is and how is should behave if we are to find this particle.

    Has Cosmic Inflation Been Discovered? – March 17, 2014
    Excerpt: Harvard cosmologist Avi Loeb gives this admission (about inflation) at the end of the article:
    “Still, there is much more to learn about our universe’s first few moments. For example, astronomers still have no idea what the substance that propelled inflation — dubbed the “inflaton” — actually is,” Loeb said.
    ,,, “We really need to understand what this substance — this inflaton — is. And until we do that, it’s just like dark matter or dark energy — we give it a name, but we don’t know what it is.”

    The Edge of Physics: Do Gravitons Really Exist?
    Excerpt: As it stands, we are far from definitively proving it exists. As Fermilab senior physicist Don Lincoln wrote in a post: “Gravitons are a theoretically reputable idea, but are not proven. So if you hear someone say that ‘gravitons are particles that generate the gravitational force,’ keep in mind that this is a reasonable statement, but by no means is it universally accepted. It will be a long time before gravitons are considered part of the established subatomic pantheon.”

    I liked Dr. Ross’s observation that he made a while back in regards to the relative percentages of the visible portion of the universe that we can detect, and the invisible portion of the universe for which we have detected no particles.

    Table 2.1 – Hugh Ross – Why The Universe Is The Way It Is?Inventory of All the Stuff That Makes Up the Universe (Visible vs. Invisible)
    Dark Energy – 72.1%
    Exotic Dark Matter – 23.3%
    Ordinary Dark Matter – 4.35%
    Ordinary Bright Matter (Stars) – 0.27%
    Planets – 0.0001%
    Invisible portion – Universe – 99.73%
    Visible portion – Universe – .27%

    ‘Dark Matter’ attributed effects were always due to ordinary matter, so never any Dark Matter required (unless one ‘believes’ in SCM-LCDM). Dark Energy also need not apply. reference ‘SPIRAL’ cosmological model ‘GRIP’ hypothesis on Galactic Rotation.
