Shedding Light on Dark Matter, Presented by David Penney, Ph.D
October 18 @ 7:00 pm - 8:30 pm| Main Library (Traverse City)
What is Dark Matter? We know what it is not, but not what it is. There were hints of its presence 100 years ago. Astronomers swept it under the rug. Now we can no longer ignore this elephant in the room.
A jazzier title might be appropriate, such as “The coming revolution in Physics and Astronomy”. It is coming sooner than most believe. We are on the brink of a huge change in Physics and Astronomy”. The Standard Model of elementary particles can’t stand. Dark Matter will eventually affect even the common man not involved in science.
Another title might be, “The Universe we don’t know – that is 95% of the Universe”. Physicists and astronomers can become puffed-up about their discoveries, even, dare say, arrogant. Albert Einstein and “relativity” squashed that condition the last time in the early 1900s. This is certain to happen again.
The subject area of dark matter enquiry is very exciting – almost science fiction-like, but it is SCIENCE. The search these last several decades has been hard-going. Huge sums of money have been spent. Some physicists now are becoming discouraged and even talk of quitting. Regardless, the search will go on. Let’s review the latest findings together.
Wednesday, October 18 @ 7:00 p.m. in the McGuire Community Room, TADL Main Library.
