Arthur Zajonc opens the Dialogue by introducing physicist Anton Zeilinger and emphasizing the shared value of open-minded skepticism. Zeilinger then uses demonstrations involving light, the double-slit experiment, photons, and polarization to explain fundamental ideas in quantum physics, including wave-particle duality, complementarity, probability, randomness, nonlocality, and entanglement. Through persistent questions, the Dalai Lama examines whether photons …

The afternoon dialogue continues the exploration of quantum physics by comparing objective randomness, nonlocality, and entanglement with Buddhist ideas of dependent origination and emptiness. The Dalai Lama questions whether apparently random quantum events might have undiscovered causes and asks how scientific discoveries affect physicists’ personal understanding of reality. The participants discuss science’s historical focus on …

David Finkelstein presents quantum theory as a new way of understanding reality that moves beyond classical ideas of fixed states, continuous space-time, and ordinary logic, using demonstrations with polarized light to explain how observation, experimental choices, and complementarity shape what can be known. The discussion develops into Finkelstein’s speculative model of quantum space-time, including discrete …

Tu Weiming reflects on how modern physics has challenged the Enlightenment ideal that rational inquiry will steadily eliminate ignorance, arguing that Western exploration of the external world should be brought into dialogue with Buddhist self-knowledge and spiritual cultivation. The Dalai Lama emphasizes that scientific knowledge should serve humanity and be balanced by careful investigation of …

Arthur Zajonc uses demonstrations involving color, prisms, electricity, optical illusions, and individual atoms to explore how human experience arises through an interaction among the observer, the object, and the means of observation. The Dalai Lama compares Western scientific accounts of perception and matter with Buddhist atomic theory, asking whether qualities such as color and texture …

The afternoon dialogue continues the exploration of quantum superposition and whether particles such as photons and electrons possess a definite, continuous existence independent of observation. The participants compare quantum analysis with the Madhyamaka distinction between conventional and ultimate truth, noting that something can function conventionally even though its inherent nature cannot be found through deeper …

George Greenstein introduces modern cosmology through images of planets, stars, nebulae, and galaxies, explaining how stars and galaxies form and disappear, how light-years allow astronomers to look into the past, and how observations support an expanding universe associated with the Big Bang. The Dalai Lama compares these ideas with Buddhist descriptions of innumerable world systems …

Continue reading “An Introduction to Modern Cosmology”

The dialogue explores recent developments in astronomy and cosmology, beginning with newly discovered planets, the search for extraterrestrial intelligence, and the Buddhist belief in countless world systems inhabited by sentient beings. The participants compare the organization and movement of planets, stars, galaxies, and galaxy clusters, then examine the cosmic afterglow, dark matter, a centerless Big …

Piet Hut uses photographs and computer simulations of colliding galaxies to explain how gravity shapes galaxies and clusters, how galactic collisions can produce new stars, and how scientific models combine precise mathematics with approximate assumptions. The Dalai Lama connects the eventual dissolution of stars, planets, and galaxies with Buddhist teachings on impermanence, suggesting that this …

In this concluding session, Eiko Ikegami reflects on the value of bringing scientific inquiry, spiritual experience, and Asian and Western traditions into genuine critical dialogue, while Piet Hut argues that science offers a powerful but incomplete view because it has not yet fully incorporated meaning, values, beauty, and subjective experience. The discussion examines whether logic …
