Review Questions

• How did the Renaissance contribute to the development of modern cosmology during the modern era?
  • The Renaissance sparked a renewed interest in science and philosophy, moving away from medieval scholasticism towards empirical observation and questioning established beliefs. This cultural movement encouraged figures like Copernicus and Galileo to explore new ideas about the cosmos. Their work laid the groundwork for modern cosmology by challenging geocentric models and promoting heliocentrism, which significantly altered humanity's understanding of its place in the universe.
• Discuss how the Scientific Revolution changed perceptions of the universe during the modern era.
  • The Scientific Revolution introduced systematic observation and experimentation as core components of scientific inquiry, shifting perceptions of the universe from mystical explanations to empirical evidence. Discoveries made during this time—such as Newton's laws of motion—revolutionized physics and astronomy. This change established a framework for understanding natural phenomena through scientific principles rather than relying on religious or traditional authorities.
• Evaluate the impact of Enlightenment ideas on modern cosmology in the context of the modern era's development.
  • The Enlightenment fostered critical thinking and a questioning attitude towards traditional beliefs, impacting how cosmology evolved during the modern era. Thinkers like Kant proposed that knowledge should be based on reason and evidence rather than dogma. This intellectual environment encouraged further exploration into astronomical theories and led to acceptance of ideas such as an expanding universe, thus shaping our current understanding of cosmological concepts like dark matter and cosmic inflation.
