Join theoretical physicist Marcelo Gleiser, writer Marjolijn van Heemstra, and physicist Carlo Rovelli in a fascinating discussion on the enigmatic nature of time, the cosmic connections of existence, and the abstract concepts of the universe. From white holes dissolving time to the transformative power of the overview effect, this podcast explores deep philosophical reflections and personal experiences that challenge our perceptions of time and space.
Time is a human construct to understand existence and change, elusive despite operational definitions.
Personal tragedies can shape one's perception and contemplation of time, intertwining sorrow and gain.
The interconnectedness of time and astronomical phenomena, like black holes, hints at potential time reversal in white holes.
Deep dives
Understanding Time Through Physics
Time is a complex concept that has intrigued physicists like Marcelo Glaser, who acknowledges that despite operational definitions, the true nature of time remains elusive. Through conversations about time's essence and the human perception of it, the podcast delves into the idea that time may be a human construct to comprehend existence and change.
The Emotional Impact of Time and Loss
The emotional connection to time is explored through personal experiences, such as Marcelo Glaser's childhood loss of his mother, leading to a profound curiosity about mortality and existence. The intertwining of time with sorrow and gain is discussed, highlighting how personal tragedies can shape one's perception and contemplation of time.
Cosmology, Black Holes, and Time Reversal
The podcast delves into cosmology and the significance of black holes in redefining our understanding of time. Marcelo Glaser's excitement at witnessing the detection of gravitational waves from merging black holes exemplifies the interconnectedness of time and astronomical phenomena, hinting at the potential of time reversal in white holes.
Gaining Serenity and Perspective Through Time
Carlo Rovelli's insights on time and its interconnectedness with human existence offer a perspective reshaped by physics. By viewing oneself as a waveform in the vast happenings of the universe, a sense of serenity and acceptance of mortality and finite existence emerges. Understanding time as fluid and impermanent fosters a broader acceptance of life's transience.
Exploring Space and Connection Beyond Chronological Time
The concept of the 'overview effect' experienced by astronauts observing Earth from space is paralleled with exploring space within Earthly environments and connections with others, fostering a sense of unity and interconnectedness. Embracing darkness to view the night sky and the interconnectedness of events, rather than static things, offers a unique perspective on existence and time.
Embracing the Unknown and Serendipity of Existence
The exploration of white holes and time reversal provides a glimpse into the unpredictable nature of existence and the interconnectedness of all things in the universe. The acceptance of mortality and the impermanence of life, as well as the significance of relationships with the universe and fellow beings, highlight a broader perspective on the fluidity and interconnectedness of time and existence.
Our lives are so rushed, so busy. Always on the clock. Counting the hours, minutes, seconds. Have you ever stopped to wonder: what are you counting? What is this thing, that’s all around us, invisible, inescapable, always running out? What is time?
