A quick reminder that tonight at 6 Pacific/9 Eastern, Sean Carroll and I will be interviewed by Alan Boyle on the online radio show “Virtually Speaking Science”. Topics will cover the LHC and other hot issues in physics, astrophysics, gravity and cosmology, as well as the scientific process. See Monday’s post for the link to the show and other details.
Continuing my more careful summary of the Higgs Symposium (held January 9-11 at the University of Edinburgh, as part of the new Higgs Center for Theoretical Physics), and improving on my quick blog posts that I put up during and just after the symposium (#1, #2 and #3), I’ve finished another article about our current knowledge and ignorance concerning the recently discovered Higgs-like particle. The new article
covers a topic that I spoke about extensively at the Symposium. The other completed articles in this series are
- 0. Introduction: Taking Stock of the “Higgs”
- 1. Is the Newly Discovered Particle a Higgs Particle of Some Type?
- 2. If the New Particle is a Higgs Particle, Might it be Composite?
- 3. Might the New Particle be a Higgs of the Simplest Possible Type (the Standard Model Higgs)?
- 4. Might there be more than one type of Higgs particle? Has our recent discovery been just the first of several that are still to come?
- 5. Supersymmetry: What Does The New Particle Teach Us About This Possibility?
One or two more segments to go.

An impressive share! I’ve just forwarded this onto a co-worker who was doing a little
homework on this. And he actually ordered me lunch simply because I found it for him…
lol. So let me reword this…. Thanks for the meal!!
But yeah, thanx for spending the time to discuss this
matter here on your website.
great points altogether, you simply gained a brand new reader.
What may you suggest in regards to your submit that you just made some days in the past?
Any certain?
Hi there, I log on to your blog like every week. Your writing style is witty, keep it up!
After I originally left a comment I seem to have clicked on the -Notify me when new comments are added- checkbox and from now on every time a comment is added I recieve four emails with the exact same comment. Is there a way you can remove me from that service? Many thanks!
“[ He said the parameters for our universe, including the Higgs mass value as well as the mass of another subatomic particle known as the top quark, suggest that we’re just at the edge of stability, in a “metastable” state. Physicists have been contemplating such a possibility for more than 30 years. Back in 1982, physicists Michael Turner and Frank Wilczek wrote in Nature that “without warning, a bubble of true vacuum could nucleate somewhere in the universe and move outwards at the speed of light, and before we realized what swept by us our protons would decay away.” … Joseph Lykken, a theoretical physicist at Fermilab.]”

Maybe, but it could also mean that the universe is cyclic in nature and will regurgitate upon collapsing on itself, space-time reverses to a point, and boom, another Big Bang.
If energy is a conserved parameter then once the “mass” dissipates space-time will reduce accordingly until all the energy converges back to a singularity. It will converge because no-mass no gravity and visa versa. Because free energy is chaotic the instability will create the next Big Bang.
Instability, the inherent nature of constant motion, will not permit the universe to come to a stable uniform temperature, maximum entropy.
I believe we have passed the half way point, assuming it is linear, because of the expansion of space-time. This means the antiparticles are now winning in annihilating the present massed particles. But as the equations show the whole thing will come crushing into a singularity at the speed of light and “explode” again. The explosion, again, is because the energy is always changing (states) and the energy pressure will be so intense that it will release again in a rapid expansion creating yet another “visible” universe. The difference between this one and the next will be the rate entropy at time = 0. It will not be necessarily the same as our universe stated, again chaos has no boundaries except for one parameter, total energy content.
