Lecture

Replaying the Tape

This module explores the intriguing concept of time travel in the context of evolution. It poses thought-provoking questions about the predictability of life's future:

  • What if we could reset the clock on evolution?
  • Would we observe similar outcomes, or would the details change?
  • Are there laws governing evolution?

By examining key evolutionary milestones—like the emergence of eukaryotic cells and multicellularity—students will gain insights into the complex narrative that has led to the biodiversity of life today.


Course Lectures
  • The Big Bang
    Lynn Rothschild

    This module takes you back to the very beginning of the universe, exploring the Big Bang and its implications for our understanding of existence. As we journey back in time, we will investigate how fundamental forces and particles emerged, setting the stage for the formation of atoms, stars, and galaxies. Concepts in cosmology will be addressed, including:

    • The nature of the universe post-Big Bang.
    • The timeline of significant cosmic events.
    • Epistemology: how we know and understand the origins of the universe.

    Students will gain insights into the vast timescales and scales of the universe.

  • This module discusses the transition from cosmic events to the formation of life's building blocks. The physical universe created by the Big Bang included essential chemicals that serve as the foundation for life. Key points include:

    • The formation of light elements in the early universe.
    • How heavier elements were produced in stars and supernovae.
    • The emergence of organic compounds and their significance in the development of life.

    Students will explore where these compounds may have originated, whether on Earth or elsewhere, emphasizing the idea that we are fundamentally made of star dust.

  • This module delves into the concept of "Pushing the Envelope for Life," examining the extremes of life as we know it. It discusses:

    • How organisms adapt to extreme environments on Earth.
    • The implications for life forms in space and on other planets.
    • Potential challenges and opportunities for human exploration beyond Earth.

    Students will analyze real-world examples of extremophiles and discuss what they reveal about the resilience of life in the universe.
