back to article Don't panic, but.. ALIEN galaxies are slamming Earth with ultra-high-energy cosmic rays

The most energetic cosmic rays bombarding Earth originate from outside our Milky Way Galaxy, according to research published just before the weekend. More than 400 scientists from 18 countries working under the Pierre Auger Collaboration wanted to solve the mystery of where these special rays – containing extremely rare and …

  1. Lysenko explosive, massive black hole in their centers...

    Isn't that an "Infinity + 1" paradox? A black hole can't "explode" because the energy required would have to exceed the infinite binding forces of an object of infinite density. All it can do is slowly evaporate via Hawking radiation.

    I'm guessing he's referring to the highly energetic reactions in the accretion disc outside the event horizon, but the wording implies that the black hole itself can generate repulsive forces sufficient to destabilise it's own structural integrity in the same sense that a supernova does which (as I understand it) is impossible because: math.

      Re: explosive, massive black hole in their centers...

      "Explosive" is certainly a poor choice of words for an object that can only consume and never repel matter.

      The theory goes that the extreme gravitational and magnetic fields around a supermassive black hole may be capable of accelerating those particles with trajectories that get very close to the event horizon - without actually crossing it - to these phenomenal speeds.

    "The exact source of the rare high-energy rays remains unknown. Since the cosmic rays are streams of charged particles, they are deflected by the magnetic fields littering the Milky Way, obfuscating the location of the source. It’s just really difficult to know where these came from."

    That's because the aliens living there don't want us to be able to find them.

    I wonder how many other planets have life on them, this can't be the only one.

Cos they'd have to have a dipolar component of anisotropy with an amplitude bigger than our galaxy can manage. That's why not. And as for that Donald Trump..."

    The 'electric universe' of charged plasma as communication of energy and information, is implicit to such observations - but joining up the dots is not allowed so much as gradually leaked to the general public.

    Perhaps the term 'alien' rightly belongs to the nature of such thinking - set apart from EVERYTHING as if to define, predict and control... the narrative if not the outcome itself.

    Alien thinking cuckolds truly shared Thought - but is it 'other' or is it simply not true - running as a programming in place of true appreciation?

    In appreciating our 'energetic' environment or relational field - as a synchronicity rather than of actions of 'parts' upon each other - and the intent of 'understanding' the sum of such 'parts' as if the 'whole', Humpty has not fallen - and all the king's motivations and machinations are redundant. However, the program may now run as the reintegrative movement of being to itself - for all awareness of existence is of the same source nature regardless its screen coordinate 'identity'.

    'Space weather' embraces more than 'space' has been designated to be. Awareness is always of tangible witnessing to existence at any and every level. Self-specialness seems to 'set apart' to run its moment of 'victory' over an all embracing unconditional 'love'. "It's love - but not as we know it Jim"

    You can still sleep soundly at night...Particles with an energy level greater than 10 EeV, and typically arriving from beyond the Milky Way, tend to hit Earth at a rate of one per square kilometre per year.

    The Particle That Broke a Cosmic Speed Limit: Physicists are beginning to unravel the mysteries of ultrahigh-energy cosmic rays, particles accelerated by the most powerful forces in the universe.

    Only recently, with the discovery of a cosmic ray “hotspot” in the sky, the detection of related high-energy cosmic particles, and a better understanding of physics at more familiar energies, have researchers secured the first footholds in the quest to understand ultrahigh-energy cosmic rays. “We’re learning things very rapidly,” said Tim Linden, a theoretical astrophysicist at the University of Chicago.


    Thomson has his money on threads of galaxies and dark matter called “filaments” that are draped throughout the cosmos and which, at hundreds of millions of light-years long, are among the largest structures in existence. There’s a filament in the direction of the hotspot. “It’s probably something in the filament,” Thomson said. In any case, he added, “we have an idea now of interesting places to look. And all we need to do is collect more data.”

    Perhaps particle jets at the poles of a supermassive black hole?

    That might explain why we don't get them from our galactic center, because the jets aren't aimed our way. But the jets from some distant galaxies are - or rather were aimed where we are now when the particles would be emitted.
