StarTalk Radio: Cosmic Queries – Before the Big Bang

Host: Neil deGrasse Tyson
Co-Host: Paul Mercurio
Release Date: March 11, 2025

1. The Superconducting Super Collider and Its Impact

Timestamp: 00:47 – 07:09

Neil deGrasse Tyson and Paul Mercurio delve into the historical significance of the Superconducting Super Collider (SSC), a massive particle accelerator project initiated in Texas during the Cold War era. Tyson humorously suggests renaming it the "Super Duper Collider" to emphasize its grandeur, while Mercurio adds, “The Gargantuan Super Collider” (03:14).

Key Points:

• Purpose of the SSC: Designed to accelerate particles to near-light speeds to discover new particles and advance our understanding of the universe.
• Superconductivity: The importance of developing room-temperature superconductors, which could revolutionize technology by allowing electricity to pass without resistance.
• Cancellation of the SSC: In the late 1980s and early 1990s, the U.S. government, under President Reagan and later President Clinton, cited budget overruns and shifting priorities to cancel the project. Tyson speculates that geopolitical changes, such as the end of the Cold War, influenced this decision (06:00).

Notable Quote:
Neil deGrasse Tyson (04:00): “Because if you can find a room temperature superconductor, Ooh, that would transform everything.”

2. The Shift of Particle Physics to Europe

Timestamp: 07:09 – 15:05

With the cancellation of the SSC, the hub of particle physics research shifted to the European Organization for Nuclear Research (CERN) in Switzerland. This led to the construction of the Large Hadron Collider (LHC), which ultimately discovered the Higgs boson, often referred to as the "God Particle."

Key Points:

• CERN’s LHC: Became the most powerful collider, leading to significant discoveries like the Higgs boson.
• Implications for U.S. Science: The U.S. lost its leading position in particle physics research, allowing European scientists to make breakthrough discoveries that the SSC might have achieved earlier.

Notable Quote:
Neil deGrasse Tyson (07:09): “The European center for Nuclear Research, CERN, which is located in Switzerland... and the LHC became the detector that found the mythical Higgs boson, the God particle.”

3. Listener Questions: What Existed Before the Big Bang?

Timestamp: 16:26 – 23:22

Tyson addresses a listener’s question from Emily in Kyoto about the nature of stardust and the origins before the Big Bang. The discussion transitions into the concept of the multiverse and the philosophical implications of existence.

Key Points:

• Stardust: Emphasizes that humans are literally made of stardust—elements forged in stars and spread across the galaxy via supernovae.
• Origin of the Universe: Discusses theories about what might have existed before the Big Bang, including the multiverse hypothesis, which posits an infinite number of universes.
• Philosophical Implications: Explores how origins questions persist unless a universe can create itself, leading to endless loops of causation.

Notable Quotes:
Neil deGrasse Tyson (34:08): “We are not only poetically, but literally stardust. We are made of ingredients that were forged in the hearts of stars.”
Emily’s Question (16:57): “What existed before the Big Bang?”

4. Time Travel and Relativity

Timestamp: 23:37 – 33:25

A listener named Umar from Seattle poses a question about the possibility of accelerating time to visit the past. Tyson and Mercurio engage in a discussion about the complexities of time travel, the effects of relativity, and its portrayal in popular culture.

Key Points:

• Relativity of Time: Explains how traveling at high speeds can slow down time relative to others, but accelerating time to visit the past remains scientifically unfeasible.
• Zeno's Paradox: Introduces Zeno’s paradox to illustrate the mathematical challenges of infinity and how it relates to movement and time.
• Pop Culture References: Discusses time travel scenarios in "Star Trek," highlighting the potential dangers of altering past events and the philosophical dilemmas they introduce.

Notable Quote:
Paul Mercurio (24:55): “Can we accelerate our time and essentially visit the past? Or does it just mean we just get old super fast?”
Neil deGrasse Tyson (27:33): “We are prisoners of the present, forever transitioning between our inaccessible past and our unknowable future.”

5. Stardust and Future Evolution

Timestamp: 33:25 – 38:26

Listener Emily from Kyoto asks whether the air we breathe contains stardust and speculates about the future evolution of life based on this cosmic foundation. Tyson elaborates on the scientific perspective of stardust and its role in biological evolution.

Key Points:

• Composition of Air: All elements essential for life, such as carbon, nitrogen, and oxygen, originated from stars, making humans and their environment literally composed of stardust.
• Future Evolution: The endless possibilities of chemical evolution driven by the periodic table, suggesting that future developments in chemistry and biology are boundless.
• Interconnectedness of the Universe: Highlights the profound connection between cosmic processes and the building blocks of life on Earth.

Notable Quotes:
Neil deGrasse Tyson (34:32): “We are made of ingredients that were forged in the hearts of stars...”
Paul Mercurio (34:26): “What does future evolution hold based on this foundation of stardust that we just talked about?”

6. Infinity in the Observable Universe and Mathematical Paradoxes

Timestamp: 39:18 – 42:25

The final listener question from Sparkman addresses the presence of infinity in the observable universe. Tyson and Mercurio explore mathematical concepts like Zeno's Paradox to explain the nature of infinity and its manifestation in reality.

Key Points:

• Infinite Universe: Discusses theories that suggest the universe might be infinite, and the implications of an endless multiverse.
• Zeno’s Paradox Revisited: Explains how infinite divisibility of space and time does not prevent reaching a destination, as the sum of an infinite series can converge to a finite value.
• Practical Implications: Explores whether infinite concepts are observable and meaningful in the physical universe versus abstract mathematics.

Notable Quotes:
Neil deGrasse Tyson (39:54): “The universe itself might be infinite. If there's a multiverse, it's pumping out an infinite number of universes...”
Paul Mercurio (41:56): “But it's so random to pick half. You could say I gotta pass the third. The point at the 1/3.”

Conclusion: Embracing the Unknown

Throughout the episode, Neil deGrasse Tyson emphasizes the importance of curiosity and the willingness to explore the unknown. He encourages listeners to keep questioning and seeking understanding, despite the vastness and complexity of the cosmos.

Final Quote:
Neil deGrasse Tyson (43:19): “This has been StarTalk's grab bag cosmic Queries from my office here at the American Museum of Natural History. Paul, thanks for coming in.”
Paul Mercurio (43:29): “As always, I bid you, keep looking up.”

Key Takeaways:

• Scientific Progress: The cancellation of major projects like the SSC can have long-lasting impacts on a country's scientific leadership and discoveries.
• Cosmic Origins: Understanding the universe's origins continues to challenge scientists, with theories like the multiverse offering potential explanations.
• Relativity and Time: While relativity allows for fascinating phenomena like time dilation, practical time travel remains beyond our current scientific capabilities.
• Stardust Connection: Our very existence is intricately linked to the cosmos, highlighting the profound interconnectedness of all matter.
• Infinity and Mathematics: Mathematical concepts of infinity, while abstract, have intriguing applications and implications for our understanding of the universe.
