PSW#2330: Understanding the Invisible Universe of Dark Matter and Dark Energy

Heart of Darkness: Understanding the Invisible Universe of Dark Matter and Dark Energy

This lecture will explore the history and the physics of our current model of the universe: How did structure in the universe arise, how has it evolved, and what is its ultimate fate? The lecture will emphasize the role of three critical aspects of rational scientific inquiry in arriving at the current cosmological paradigm: The application of direct measurement and observation, the use of rigorous mathematical modeling, and the requirement that hypotheses be testable and verifiable. And, while pointing out how the current paradigm has met critical analysis thus far and "works" to great precision, the lecture will also discuss some fundamental questions about the cosmos that the current model does not answer.

    What is Dark Matter? I call it Negative gravity. That, of course, rapidly expands our universe. I believe the M theory.

      Dark matter is the extra gravity that holds galaxies together. Dark energy is what is causing the universe to expand.

      M theory is a result of the Second Superstring revolution that happened in the mid 1990's. It is not clear that it has anything to do with Dark Energy or Dark Matter.

    And, I welcome anyone to discuss this with me at these events. I showed up kind of late to this one.

    I haven't seen it posted, but I'd like to know what the preferred attire is for these lectures. Any information provided is most appreciated.

      You can wear any thing. I've seen folks in jeans and t-shirts and folks in tuxes having come from dinner at the club. The meeting room isn't fancy and they are thrilled to get a crowd. Note: the entrance to the meeting room is in back of the club on the left when you enter the parking lot. Do not go in the main entrance.

      Thank you for clarifying, Kathy; I'm looking forward to listening to this lecture.
