ST. PETER — If our mysterious universe was born in a big bang 13.8 billion years ago, it was at that moment so small and compact as to defy imagination. Science can’t go back, but its particle accelerators are trying to re-create the primordial universe.
Gustavus Adolphus College’s 49th Nobel Conference, “The Universe at its Limits,” searches for the connections between the vastness of the universe and the tiniest bits of matter. The two-day conference begins Oct. 1 and is streamed live online.
This is the Nobel Conference chair and physics professor Steve Mellema has long argued for. But he has also long been aware of physics’ reputation for being inaccessible and esoteric, which are fancy ways to say regular people are bored by what little of it they can understand.
He said the conference’s organizers took care to pick speakers who were not only at the cutting edge of their fields but who could condense the most important parts of their findings to a regular audience.
Mellema gave a conference preview Wednesday to a group of a few dozen at the Linnaeus Arboretum.
Consider light, he said. Even the closest star, Alpha Centauri, is 4.4 light years away, meaning it takes light that long to get to Earth. This means that if you look up and see the star, you’re actually seeing it as it was 4.4 years ago. It could have gone supernova, but we wouldn’t know until the light journeyed here.
“Telescopes are time machines,” he said.
Physics professor and Nobel Conference Director Chuck Niederriter interviewed and wrote about the eight lecturers for the conference magazine. These descriptions are mostly taken from his work.
Wilczek, a physics professor at the Massachusetts Institute of Technology, shared the 2004 Nobel Prize in physics with two other scientists for his discovery of “asymptotic freedom.” This theory says that “the closer quarks are to each other, the less the strong interaction between them.”
