High Energy Politics

It’s a rare political race where particle physics might come up, but IL-14, Denny Hastert’s former seat, is just such a delightful intersection. And Bill Foster is that Heinlein-esque synthesis; a businessman who started the firm that revolutionized theatre lighting and invented the Source 4 ellipsoidal reflector spotlight, turned award winning physicist, and now candidate.

To appreciate what kind of congressman Foster might become, it’s worth considering what kind of primary campaign he ran: he provides the option of healthcare insurance to all his paid staff; he ran a clean, non negative primary campaign stressing his positions on issues; Foster opposes the war in Iraq, champions legitimate, unfettered science and research, and supports stem cell research, just to name a few. To appreciate the scientific side of Dr Bill Foster, follow me below to examine one of the most fascinating, spectacular light-shows our universe can serve up.

Bill Foster for Congress

Stars that blow themselves to smithereens often produce magnificent sights before, during, and especially after an official supernova explosion. The enigmatic Eta Carinae, below left, is thought to contain a highly unstable star on the precipice of a hypernova. The lacy remains of a supernova observed in 1054 AD is now the Crab Nebula, a tiny, rapidly rotating neutron star lurks noisily inside.

   

The three schematics below courtesy of graphic artist Karen Wehrstein illustrate the basics of what is thought to happen deep inside a massive, aging star near the end of its life, during a classic kind of Supernova called a Type ll. After burning successively heavier elements, the star eventually begins producing iron at its center. It's a stellar dead end. The iron core grows, robbing the star of energy due to the idiosyncrasies (See comment) of atomic physics, and soon reaches a critical threshold; a massive ball of iron thousands of kilometers in diameter suddenly collapses dramatically, like a soap bubble, into an unimaginably dense remnant a few kilometers wide. Overlying superheated plasma, compressed so much it weighs way more than lead -- quickly falls in to fill the gaping void. When it slams in to the surface of the degenerate core it begans fusing furiously. Short version: Star Go Ka-BOOM!

     

Phil Plait, who did his dissertation on SN1987A, adds a little more detail:

This does two things: it sets up a huge rebound, sending the outer layers of the star back out, and also releases a vast number of neutrinos .. The gas from the outer layers absorbs these neutrinos, which is like lighting a match in a fireworks factory. The outer layers explode upwards, and several solar masses of doomed star tear outwards at speeds of several thousand kilometers per second.

Under normal conditions, neutrinos are ghostly little particles that overwhelmingly zip through ordinary matter, even a million miles of solid lead, like it was so much hard vacuum. They dwell in an incomprehensible universe seething with subatomic wraiths, not quite pure energy, not entirely solid matter, but a whiff of both. These are not ‘ordinary’ objects. The neutrino represented as a little dot or arrow racing around is an avatar of sorts; a symbolic construct of a hazy particulate property from the surreal world of high energy physics that our large, clunky macro-minds can latch on to. They’re sleeting through you by the trillions as you read this. No need for alarm though: fortunately for us, they don’t interact with the matter in our body!

But every now and then, one in uncounted zillions will cause a sub-atomic change which can in turn produce a tiny flash of light. So, with a giant tank of a clear substance, shielded from as much radiation as possible, surrounded by sensitive photo detectors, every now and then a lone of neutrino can be confirmed. Since these little guys whip through ordinary matter effortlessly, they’re a potential window deep into high energy places we cannot directly observe, like the fusing core of a star. And since a single light ray can take up to a million years to stagger drunkenly out of a stellar core, while neutrinos simply slip through the outer layers of plasma, neutrinos also uniquely offer current information about the state of affairs in places we can’t otherwise observe in real time.

On February 23, 1987, three separate neutrino detectors recorded a spike lasting just a few seconds. This was a strong indication that somewhere in the universe, something really, really big and no doubt violent beyond imagination had happened.

The next day several astronomers, amateur and professional, reported a small but bright point in a nearby dwarf galaxy called the Large Magellanic Cloud. Within a few hours of that report pretty much every telescope in the southern hemisphere had swung to the anomaly. The source was a star estimated to be twenty times heavier than our sun. Except now it was gone, and in its place was the blazing Supernova 1987A.  Right: Several frames taken over the course of a decade by the Hubble Space Telescope, and after the initial supernova faded, show the effects of secondary spasms of invisible gas expelled at extreme velocity smacking into a ring of previously ejected material.  

One of the instruments that recorded a spike was the Irving-Michigan-Brookhaven proton decay detector. The futuristic chamber of ultra pure water surrounded by two-thousand photodetectors is shown left (The source of the bubbles is a diver inspecting the equipment). Bill Foster played a significant role in the development of the IMB. When the neutrinos set off alarm bells in 1987, Foster had moved on to Fermilab. But because of his involvement with the IMB detector and the subsequent neutrino detection from SN1987A, Foster and his team shared in the 1989 Rossi Prize in high energy physics.

If anything like SN1987A happened too near our planet, the earth would evaporate faster than a snowflake in a bonfire. And yet we may owe our existence to these violent events. The shock wave from SN 1987A will travel outward, essentially forever. Along the way it will combine with other blast fronts, forming waves of compactions and rarefactions in the medium of thin interstellar gas. Simultaneously it will salt those vast clouds of buoyant hydrogen and helium with heavier substances, volatile gases, ices, and metals. The immense waves will diffract causing nodes, small pockets will condense here and there. Gravity will take hold, and the knots of gas will shrink under their own weight, they will begin to glow with dozens of individual sparks, each lighting up the infant stellar nursery from inside. In the center of each spark, pressure and temperature will grow so high that hydrogen will begin to fuse: this is the birth of stars, this is how our own solar system may have arisen five billion years ago.

Speaking purely for myself, as an interesting side note about SN1987A: That primary ring allows astronomers to calculate the distance between us and SN1987A using simple trigonometry. That distance is about 168,000 light-years, meaning the proginator star blew up about 160,000 years before young earth creationists believe the universe began. In addition, short lived isotopes can be seen decaying in the spectra from SN1987A. That is a direct, empirical observation that radio decay rates in the past were the same as predicted by atomic theory and observed in labs today.

Thus, SN1987A is like a Wrecking Ball of Reality to two basic tenets in Young Earth Creationist apologetics: The age of the universe and the validity of radiometric dating. Doesn't it seem fitting then, in some cosmic way, that the candidate who contributed to our elegant understanding of the universe should prevail over the other fellow, who hails from a party where antiscientific concepts like climate change denial and creationism are badges of honor?

The polling in what should be an easy GOP victory shows Foster in a dead heat with Republican opponent Jim Oberweis. Republicans are intersted in holding the seat (John McCain is reportedly going to hold an Oberweis fundraiser with a goal of 200,000 dollars). So, if that poll is close to accurate, it is a blinking red warning that this campaign needs every vote, every volunteer, and every dollar it can muster to succeed.

Given the obvious difference between these two candidates, it seems a no brainer that the residents of IL-14 would be best served by Oberwies staying in town, and focusing on improving his already scrumptious home-made ice cream. Whereas voters in IL-14 would be far better represented by a Congressman with Bill Foster’s intellect and accomplishments serving their collective interests in Washington, DC.

If Foster manages to pull this off, it will send a powerful message about what may be in store for other 'safe GOP seats' in 2008 -- a progressive message that incidentally embraces science and reason -- well beyond the confines of Illinois' fourteenth district, and into every nook and cranny in this nation. So if I didn't convince you up there, I hope I've provided you some reason to give Bill Foster's qualifications a second look down here.
