    Default The search for dark matter

    All of the natural world, all of reality, is composed of quantum fields. What we think of as particles is a convenient fiction.

    Sidebar: My prediction for the top five discoveries of the next 20 years:

    Discovery of dark matter
    Discovery of dark energy
    Discovery of habitable exoplanets
    Discovery of Ghengis Kahn's tomb
    Unification of quantum mechanics and general relativity

    Higgs boson examined as source of dark matter at the LHC

    It’s been calculated that dark matter is around five times more common than regular matter – and yet, we still haven’t directly detected it. Many different types of experiments are trying to find it, and now CERN has joined the hunt, testing whether the famous Higgs boson could decay into dark matter.

    The Large Hadron Collider (LHC) probes the secrets of the universe by smashing particles together at incredible speeds. In doing so, new and exotic types of particles are often created, giving scientists a fleeting opportunity to study things that would be virtually impossible to come across naturally.

    One of the most groundbreaking discoveries made by the LHC is the Higgs boson, in 2012. This long-hypothesized particle was the last remaining puzzle piece in the Standard Model of particle physics, believed to create the means by which other elementary particles gain mass.

    Since its discovery, scientists have used the Higgs boson as a tool to probe other particle physics mysteries. The boson quickly decays into other particles, and it’s predicted that some may not be directly detectable by the equipment.

    Given the Higgs boson’s role in “giving” particles mass, and dark matter only being detectable through its mass, the two should interact with each other. So for the new study, scientists with the ATLAS collaboration at CERN set out to check whether the Higgs boson may be decaying into dark matter.

    I seriously doubt that Kahn's tomb will ever be found.

    Dark matter. That sounds racist and you therefore are a racist you racist!

    Well, that is how the Progressive Left rolls these days isn't it?

    I doubt there will be any unification in the next 20 years.

    A reasonable conclusion. The Mongolians apparently are reticent to let people search for the tomb.

    ^ an attempt at rightwing humour.

    ^ Sounds like you have never heard of dark matter, which happens to be one of the most important research topics in physics of the last 30 years.

    You appear to be deficient in rudimentary scientific knowledge. Let me guess, you think climate change is a Chinese hoax, the Earth is 6000 years old, and early humans kept dinosaurs as pets.

    Better understanding requires dropping pretenses.

    Only a truly open mind can accept the unexpected.

    You could well be correct.

    I was holding out hope that string theory would unify quantum mechanics and general relativity. But from what I can tell, string theory seems to be faltering. Rats!

    Considering how many billions of dollars the Europeans spent on the CERN particle accelerator, it would be surprising if all they had to show for it was the Higgs boson, important though it may be. Perhaps cosmology will replace particle physics as the top dog in physics this century.

    Why the Higgs Boson Discovery Is Disappointing, According to the Smartest Man in the World

    It's been 35 years, and when it comes to new particles and the like, there really hasn't been a single surprise. (The discovery of neutrino masses is a partial counterexample, as are various discoveries in cosmology.) Experiments have certainly discovered things--the W and Z bosons, the validity of QCD, the top quark. But all of them were as expected from the Standard Model; there were no surprises.

    At some level I'm actually a little disappointed. I've made no secret--even to Peter Higgs--that I've never especially liked the Higgs mechanism. It's always seemed like a hack. And I've always hoped that in the end there'd be something more elegant and deep responsible for something as fundamental as the masses of particles. But it appears that nature is just picking what seems like a pedestrian solution to the problem: the Higgs mechanism in the Standard Model...

    If the Standard Model is correct, yesterday's announcement is likely to be the last major discovery that could be made in a particle accelerator in our generation. Now, of course, there could be surprises, but it's not clear how much one should bet on them.

    Have they investigated the interior of your skull yet? Oh wait, I guess they would first need to invent a method of penetration. I doubt diamond drill bits would do it, and carbide probably wouldn't even scratch it.

    I do not see a career as professional comedian in your future

    You obviously do not appreciate attempts to elevate the tone at jpp, and ever seek to lower it.

    If particle physics and cosmology is not your bag, I am sure there are threads about human poop in front of Pelosi's house around here somewhere.

    Apparently, dark matter cannot be any type of normal matter we simply have may have difficulty visually observing and confirming.

    Gravitational micro-lensing studies seemingly rule out while dwarfs, brown dwarfs, neutron stars, black holes as the source of dark matter.

    Dark matter is evidently some entirely unknown manifestation of physics we do not know about - some science journalists are speculating we need a new Einstein to make any fundamental breakthroughs in particle physics and cosmology.

    Default Dark energy = Einstein's cosmological constant?

    Einstein thought the cosmological constant was his greatest blunder, but apparently in hindsight it may have been a mathematical description of dark energy.
    Here is where science and philosophy diverge. Asserting that empty space has an inherent energy is purely mechanistic and has little explanatory power. IMO.

    One of the simplest explanations is that it is a “cosmological constant” – a result of the energy of empty space itself – an idea introduced by Albert Einstein.

    Many physicists aren’t satisfied with this explanation, though. They want a more fundamental description of its nature.

    Our results show that about 69% of our universe’s energy is dark energy. They also demonstrate, once again, that Einstein’s simplest form of dark energy – the cosmological constant – agrees the most with our observations.

    When combining the information from our map with other cosmological probes, such as the cosmic microwave background – the light left over from the big bang – they all seem to prefer the cosmological constant over more exotic explanations of dark energy.
