We have good evidence that the universe we see around us is not forever. The universe started expanding from a hot dense state known as the Big Bang. The universe still is expanding and cooling, leaving fossil evidence from what happened as the universe expanded. These fossils are the evidence that our universe really is evolving. Yet the theory of the expanding universe is incomplete. I will explain what we know and do not know; so many questions remain. What was the Universe doing before it was expanding? What is the dark matter that dominates the mass of the Universe? Steven Weinberg's research on particle physics introduced the idea of dark matter, but we still do not fully understand its interplay with the Standard Model of Particle Theory that Weinberg did so much to establish. We are leaving fascinating problems for research by new generations of scientists.
Dr. Peebles’ lecture will be followed by a Q&A, and we will share online participant questions with him. Registration is encouraged so that we can keep you updated on the event, and we will share the Zoom Webinar link closer to the event date via email.
