DailyDirt: Making Progress In Particle Physics
from the urls-we-dig-up dept
If you look at the history of physics, there have been plenty of significant discoveries (as well as misconceptions). As technology gets better and better, the time interval between notable findings seems to be decreasing -- and it looks like we're making progress in understanding how the universe works. (But who knows, we could also discover some phenomenon so puzzling that we'd have to re-write everything.) Obviously, we don't know everything yet, but here are just a few recent milestones that bolster the Standard Model of particle physics.- The Higgs Boson has been found, and the Nobel prize was bestowed on Peter Higgs and Francois Englert for the theoretical discovery of a fundamental particle that contributes to our understanding of the origin of mass. Higgs submitted a paper in 1964 describing his namesake particle, and the evidence to support its existence was found in 2012. [url]
- The first detection of gravity waves is on the way, optimistically to be seen in the next few years. Physicists have been looking for over 40 years, but now we have more accurate instruments and also a better idea of how often we should see something (just about once a week). [url]
- For nearly two decades, scientists at the Fermi National Accelerator Laboratory were trying to create a single top quark using the weak nuclear force, and they've finally announced they did it. This announcement comes *after* the shutdown of Fermilab's Tevatron because it took some time to analyze the data from over 500 trillion proton-antiproton collisions produced by the Tevatron from 2001 to 2011.

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

Is the Higgs Field infinite or does it only occupy space-time? If it does stretch, is there a breaking point? Could it also be possible the Higgs Field doesn't fill space, but actually is space, as in it is the very fabric of reality itself?
All kinds of subatomic particles wink in and out of existence continuously, which I believe has been proven experimentally. Perhaps the Higgs Field is responsible in some way for this as well? Especially considering how (from the article) breaking off a particle of it causes that particle to immediately disintegrates into a multitude of subatomic particles.
If we can figure out how to manipulate the Higgs Field, could we not then increase and decrease the mass of an object (say a person) situated within that manipulated field, effectively causing a person to have no mass and therefore not be affected by gravity?
So many questions, so few answers. The mind races at the possibilities, if not for reality, then for science fiction at the very least lol. :-)

Re:
The existence of the Higgs field must be universal - like the electric field, the gravitational field and the fermionic fields that give rise to the electron etc etc.
The value of the Higgs field in vacuum could (in principle) change from place to place - BUT that would create an energy gradient that would self resolve at the speed of light See Coleman's paper "The fate of the false vacuum"

Re: Re:
What Higgs did was to put the two theories together, stir the mathematical pot a bit and then... Voila! the two sets of massless particles stuck together and became massive as if by magic.
The remaining problem was that we didn't see the massive particles either.
Of course if you can't see a massive particle that isn't a problem - it may just mean you haven't cranked up you particle accelerator enough.
For the last 50 years physicists have been progressively cranking up their accelerators - and finally they found all the massive particles - the lst being the so called Higgs itself.

Re: Re: Re:
Magnetic fields expand and contract, so perhaps it's possible for the Higgs Field to do the same. I know I'm thinking of this in very simplified terms, but I'm just a layman obviously.
Figuring out the rest of it (unified theory woohoo!) and especially how to manipulate these physical laws as we discover them, the same way we already do to some of it (manipulating electrons changed the world entirely), is an important game changer in regards to our survival I think. Especially gravity; I'm thinking cold fusion here just for starters, space travel and super dense materials as well. Plus I won't lie; the thought of having the means to negate gravity altogether just sounds like a whole lot of fun lol.
Of course that is only so long as we can resist the temptation to abuse these discoveries for immoral reasons, the splitting of the atom being the last big one. The jury is still out on whether that was a good idea, despite the fact it helped bring an end to a costly war. "But power plants!" some might says. Sure it's great for that, until you have a meltdown. And lets not forget these types of power plants also power submarines carrying nuclear munitions.
Suffice it to say discoveries like the Higgs Field give me hope for the future, but at the same time that enthusiasm is tempered by the knowledge it may perhaps also rob of us any future. Sigh...
