What will we do when the light goes out?

While that might not be something most people think about, scientists say that it will happen to our sun some time in the distant future. That question and many others will be examined by scientist Sy Gonzales at the next Central Colorado Humanist Sunday Science program at 10 a.m. Sunday, July 7.  The program explores a future including what will happen as our sun begins to age and deplete its nuclear fuel.

The presentation at the Salida Scout Hut, 210 E. Sackett St., will examine the history of our planet earth, estimated to be more than 4.5 billion years old, as well as a look at the deep future of the sun and our planet, based on the latest scientific advances.

Gonzales is expected to discuss topics including what earth’s future geography may look like, whether our disappearing glaciers will ever return and related subjects.

The sun’s life cycle is well understood to modern science. Gonzales will talk about surprising aspects of thermonuclear fusion in the sun and what happens when a star like our runs out of its nuclear fuel. He’ll also discuss a projected big change to our Milky Way galaxy.

Gonzales is a retired mathematician and computer scientist. He holds degrees in applied mathematics, mathematics and computer science and developed engineering software during a 35-year career.

The Central Colorado Humanists sponsor Sunday Science presentations on the first Sunday of each month. Each presentation features a science topic understandable by both scientists and non-scientists. A discussion and light refreshments will follow the talk.

Admission is free while donations are welcomed to help offset costs. Doors open at 9:30 a.m. to allow the program to begin promptly.
