Course Lectures
  • The Big Bang
    Lynn Rothschild

    This module delves into the origins of the universe, beginning with the Big Bang. It emphasizes the importance of understanding the cosmos to grasp the evolutionary history of life on Earth. The concepts of cosmology, including time and scale, will be explored to help students comprehend the vastness of the universe.

    Key points include:

    • The timeline of the universe's development
    • The formation of fundamental forces and elements
    • Epistemology in cosmology and its implications
  • This module discusses how the physical universe, born from the Big Bang, set the stage for the emergence of life. It covers the formation of chemical building blocks essential for life, including:

    • Atoms and elements created in the early universe
    • Formation of molecules in interstellar environments
    • The role of water as a solvent for life

    Students will explore whether life's essential compounds originated on Earth or were delivered by cosmic processes, highlighting recent discoveries in astrochemistry that suggest these compounds may represent a universal language.

  • This lecture focuses on the concept of "Pushing the Envelope for Life," examining the limits and potential for life in extreme environments. It encourages students to think critically about the adaptability of life forms and the conditions necessary for their survival. Discussions will include:

    • Extreme environments on Earth and their inhabitants
    • Potential habitats in space
    • Implications for extraterrestrial life

    Through engaging examples, students will understand how life can thrive in conditions previously thought inhospitable.
