NORMAL – A recently-revealed collision of two neutron stars is shedding new light on some of the mysteries of our universe, including how gold was created.

In August, a NASA telescope detected signals from the space crash after traveling 130 million light-years.

PODCAST: Listen to Scott’s interview with Willmitch on WJBC.

“It was such a violent event, that it freed up all this energy, and this energy went into the making of the heavy elements like gold,” Illinois State University planetarium director Thomas Willmitch said. “This is actually not a surprise that this process took place, but we have never seen anything like this before.”

Willmitch told WJBC’s Scott Laughlin, Albert Einstein got it right 100 years ago.

“For a century we could not detect them and that was actually predicted by Einstein,” Willmitch said. “He said this is going to be so subtle that it’s going to be impossible to measure. It was impossible to measure until two years ago.”

Willmitch likened it to finding a strand of human hair 26,000 miles away.

Pritzker, recall another Illinois Governor who protested the incursion of armed federal personnel into the city.   Those federal troops, rather than calming, escalated the situation, leading to deaths and violence.

In these troubled times, to my fellow white Americans

By Mike Matejka Our nation is at a unique watershed in human relations. African-Americans have been killed too many times in the past before George Floyd, but the response to this man’s death is international and all-encompassing. I was a grade-schooler during the Civil Rights 1960s. I watched Birmingham demonstrators hosed and the Selma – Montgomery…

Workers’ Memorial Day – Remember those whose job took their life

Looking around our community, when we say employer, most will respond to State Farm, Country, or Illinois State University.   We too often forget those who are building our roads, serving our food, or our public employees. COVID-19 has made us more aware of the risk.  Going to work every day for some people means…
