Neil deGrasse Tyson | This Past Weekend w/ Theo Von #683

The "StarTalkified" Universe [00:00:00]

• Neil deGrasse Tyson introduces his new book, "Lost in Space: 5,000 Facts for Navigating the Universe."
• The book is a collaboration between his podcast, StarTalk, and National Geographic Books.
• Facts are "StarTalkified" with pop culture references to make them more engaging and memorable.
• Example: The sun's width is equivalent to 100 Earths lined up.

  "The sun were a sesame seed bagel, Earth would be the size of one of the sesame seeds."

Brain vs. Galaxy [00:03:53]

• Tyson shares a fact from his book: the human brain has 100 times more synaptic connections than stars in the Milky Way.
• This leads to the question of whether the human brain is more complex than the universe itself.
• The brain's complexity involves chemical and electrical reactions influenced by past memories and emotions.

  "The universe inside your head is surely more complex than the universe itself, which brings the question, how is it possible that the universe can make something more complex than itself?"

The Multiverse Hypothesis [00:05:51]

• The Big Bang theory pushes the question of origins further back.
• Some equations suggest the existence of other universes, leading to the concept of a multiverse.
• If there's a multiverse, our universe is just one of many.

  "So maybe there's not just a universe. Maybe there's a multiverse."

Evolutionary Roots of Thought [00:08:04]

• Evolutionary biologists suggest early thoughts were sufficient for survival and procreation.
• Curiosity about dangerous things could be selected against (e.g., getting eaten by a lion).
• Fear and caution were advantageous for survival.

  "Curiosity is not always a good thing for your survival if you're curious about things that could kill you."

Tribalism and Modern Hijacking [00:13:01]

• Early tribal behaviors, like seeking a provider (alpha male), were crucial for survival.
• These primal urges have been "hijacked" in modern civilization by fame and superficiality.
• Famous people, rather than providers, now capture attention due to these ingrained urges.

  "Famous people have hijacked that element of our tribal behavior."

The Enduring Power of Tribalism [00:16:07]

• Despite modern conveniences, tribal urges persist, leading to conflict even among similar groups.
• Examples include religious and ethnic divisions.
• This deep-seated tribalism, combined with powerful weapons, poses a risk to humanity.

  "So it is so deeply within us that even if we were the same, we would find ways to tribalize against it."

The Role of Social Media [00:20:05]

• Social media acts as an "outrage engine," feeding tribal urges and conflict.
• Advertisers exploit these primal urges for profit.

  "Social media is an outrage engine."

Space Exploration and Privatization [00:24:12]

• Elon Musk's SpaceX is launching thousands of satellites, contributing to space debris.
• The potential for a "Kessler effect" threatens to make Earth's orbit unusable.
• A video shows the extensive debris orbiting Earth.

  "The debris that we are actively tracking."

The Kessler Effect Explained [00:27:03]

• The Kessler effect describes a cascade where one satellite collision creates more debris, leading to the destruction of all satellites.
• Movies like "Gravity" depicted this scenario.
• The number of satellites and space objects is increasing dramatically.

  "If a single satellite gets destroyed, there are enough other satellites ready to be destroyed by its debris that it systematically destroys 100% of the satellites in orbit."

The Artemis Accords and Space Resources [00:32:16]

• The Artemis Accords, unlike the Outer Space Treaty, allow for business interests in space, such as mining asteroids.
• Key countries like Russia and China have not signed the accords.
• The utilization of space resources is framed as beneficial for humankind.

  "The extraction and utilization of space resources. Recovery from moon, Mars, comets, asteroids should be executed in a matter that complies with the treaty."

Generational Ships and Saviors [00:36:39]

• The concept of generational ships for long-distance space travel is discussed.
• The idea of a chosen savior being born on such a ship is explored as a recurring narrative trope.

  "Someone... They are the chosen one. They are the savior. They're the one."

The Future of Science: Playing God [00:44:57]

• Tyson predicts future scientific advancement will involve manipulating the human genome.
• He expresses concern about the potential loss of individuality and the "boutique-y" nature of human traits.
• He praises "unreasonable people" who break rules and challenge norms as drivers of progress.

  "Reasonable people follow rules and do what they're told. Unreasonable people break rules and do things that they're not supposed to do."

The Importance of Variety and Difference [00:47:22]

• The universe is largely composed of hydrogen and helium, but the small percentage of other elements drives complexity and life.
• Tyson advocates for celebrating differences rather than conforming to perceived norms.

  "You got to have variety. You got to have difference."

Carl Sagan's Pale Blue Dot [00:51:53]

• Tyson reads a passage from Carl Sagan's "Pale Blue Dot" to emphasize Earth's smallness in the cosmos.
• The quote highlights the futility of human conflicts and self-importance.

  "Our posturings, our imagined self-importance, the delusion that we have some privileged position in the universe are challenged by this point of pale light."

The Nature of Space and Aliens [00:54:14]

• The question of whether space is "gay or straight" is humorously answered as "bi" due to its spectrum of properties.
• The Betty and Barney Hill abduction case is mentioned as an early instance of a mixed-race couple's alleged alien encounter.
• The prevalence of UFO sightings in English-speaking countries is noted, with speculation on reporting differences.

  "The overwhelming majority are white people and English-speaking people."

Black People vs. Aliens [00:57:40]

• A speculative movie concept is proposed: a final battle between black humans and aliens.
• This idea draws parallels to blaxploitation films and the notion of resistance against an overwhelming force.
• Jazz music is suggested as a potential way to appease aliens.

  "I believe that that is going to be the, that's going to be the battle. And I believe that, uh, that they saved the planet."

Alien Technology and Wormholes [01:02:10]

• Aliens might possess advanced technology, such as the ability to create wormholes using negative gravity.
• This would allow for instantaneous travel, bypassing the need for spaceships.

  "If you can make a negative gravity thing, instead of bringing things together, which gravity does, it pries things apart, which is what you need to make a wormhole."

The Periodic Table and Discovery [01:05:40]

• The periodic table of elements is discussed, including manufactured elements like technetium.
• Tyson notes that the number of discovered elements has increased significantly over time.
• The discovery of new subatomic particles is also mentioned.

  "Nature only makes 92 of them. Wow. We've manufactured."

Space Travel and Human Physiology [01:09:13]

• The physical challenges of space travel are detailed, including potential head swelling and nausea.
• Sex in space is discussed, with the need for straps due to zero gravity.
• The possibility of ejaculation and ovulation in space is confirmed.

  "If you're going to put your life at risk in that way, I want to go farther. Give me something, a place to go."

The Future of Space Exploration [01:13:45]

• Space exploration is becoming increasingly privatized, with companies like SpaceX and Blue Origin playing major roles.
• Concerns are raised about the potential "gentrification" of space.
• The Outer Space Treaty and the newer Artemis Accords are discussed in the context of space governance.

  "No nation can claim sovereignty or ownership of outer space, the moon, or other planets."

The "Lost in Space" Book Tour [01:18:45]

• Tyson highlights the book's engaging format, with "galactic biscuits" of information.
• He discusses the book's chapter on the Zodiac and alien encounters.
• The book aims to make learning fun and accessible.

  "Learn something for a change."

Halloween and Identity [01:22:00]

• Tyson explains his lack of interest in Halloween as a child, stemming from a literal mindset.
• He later developed an appreciation for embracing emotions and fantasies.
• He describes a childhood fantasy of being a "geek protector."

  "I would be a nerd savior man."

The Rise of the Geeks [01:25:48]

• Geeks have become powerful in modern society due to their technological expertise.
• A hypothesis is presented: technologies created by individuals on the spectrum might lack human element sensitivity.

  "Should we be surprised that that next wave technology has no understanding or sensitivity to the human element, the interpersonal human element?"

The Uniqueness of Human Experience [01:28:07]

• Tyson emphasizes the importance of variety and difference, comparing it to the small percentage of elements that form complex life.
• He advocates for celebrating individuality rather than conforming to norms.

  "It's the forces we put on ourselves to try to make people conform to what is normal or average."

The Power of Marriage and Diplomacy [01:31:39]

• Marriage is presented as a historically potent tool for peace and inter-group acceptance.
• The concept of "beige power" suggests that ultimate outcomes are often mundane and unifying.

  "I think it all ends really beige, man."
