Get Sleepy: "A Sleepy Space Cruise to Andromeda"

Host: Thomas
Produced by: Slumber Studios
Episode Date: November 10, 2025

Episode Overview

In this tranquil episode of Get Sleepy, Thomas gently takes listeners on a meditative, imaginative journey from Earth, through the vast Milky Way, and out across the intergalactic void to the majestic Andromeda Galaxy. Alongside calming science storytelling, he explores cosmic wonders—galaxies, dark matter, the search for alien life—making awe-inspiring astrophysical concepts accessible and soothing, all with the goal of soothing listeners toward restful sleep.

Key Discussion Points & Insights

Beginning the Journey: Relaxation and Presence

Timestamps: 02:06 – 04:55

• Thomas invites listeners to become aware of their bodies and the warmth of their bedding, focusing on comfort and breath.
• The transition into imagination: Letting the sound of his voice guide listeners into the "here and now," before setting course for Andromeda.
• Quote:

  "Tune your mind's focus into the body. As you lie in your bed, notice where your body is in contact with the mattress... creating a safe, warm and sleepy cocoon for you to rest in." — Thomas (03:40)

Our Galactic Neighborhood: The Milky Way

Timestamps: 04:55 – 11:35

• Thomas paints the Milky Way as a giant, flat disc—over 100,000 light years in diameter.
• Earth’s position: midway between the Milky Way’s center and edge (about 25,000 light years from both).
• Shapes of galaxies: Spiral (like the Milky Way), Elliptical, and Irregular, based on Edwin Hubble’s classification.
• Lifecycle of stars and galaxies, including formation from nebulas and galactic evolution.

The Limits of Intergalactic Travel

Timestamps: 11:35 – 18:47

• Theoretical physics vs. sci-fi imagination: Thomas explains why traveling at or beyond light speed isn’t currently possible for humans (relativity, mass increase).
• Fastest human-made spacecraft (New Horizons) moves at 16 km/s—a fraction compared to light’s speed.
• Discussion of wormholes as "tunnels" through spacetime: still hypothetical, but familiar in science fiction.
• Quote:

  “It seems impossible or at least implausible that a human being will ever travel at light speed... So what if there’s another option? Maybe we could use shortcuts.” — Thomas (15:30)

Other Stars, Other Worlds: Alpha Centauri and Exoplanets

Timestamps: 18:47 – 23:40

• Imaginative flyby of Alpha Centauri, our nearest star system (4 light years away), which is a triple-star system.
• Introduction to Proxima Centauri B, the closest known exoplanet in a "habitable zone."
• Explanation of habitable zones and the abundance/longevity of red dwarf stars.
• Quote:

  “Exoplanet simply means planet outside of the solar system… this one, Proxima Centauri B, is in the so-called habitable region around its star.” — Thomas (22:28)

Escaping The Milky Way: Galactic Structure and Evolution

Timestamps: 23:40 – 27:55

• The journey continues: Leaving the Milky Way, passing by smaller galaxies like the Canis Major Dwarf.
• Mergers and growth: Galaxies can absorb others, growing in size and changing shape.
• Galactic year: Sun orbits Milky Way’s center roughly every 200 million years.

In the Intergalactic Void

Timestamps: 27:55 – 30:29

• Description of intergalactic space: nearly an absolute vacuum, yet not completely empty (one hydrogen atom per cubic meter on average).
• Discovery of "intergalactic stars"—stellar outcasts between galaxies.

Andromeda: Dark Matter and Galactic Mysteries

Timestamps: 30:29 – 40:49

• Arrival at Andromeda, our closest large spiral neighbor.
• Introduction to the concept of dark matter—how astrophysicists deduced invisible mass due to "abnormalities" in galactic rotation (Fritz Zwicky and Vera Rubin's work).
• Possibilities for what "dark matter" is: faint objects we know (red dwarfs, black holes), unknown particles, or flaws in our understanding of gravitation.
• Quote:

  “In the Milky Way, it would have to be close to 90% of the total mass of the galaxy... In other words, 90% of the matter contained in our own galaxy would be invisible and unknown." — Thomas (38:02)

The Search for Life and the Fermi Paradox

Timestamps: 40:49 – 51:11

• The abundance of planets hints that life elsewhere is likely, but we’ve detected no evidence—introducing the Fermi Paradox.
• Explores potential solutions: The "zoo hypothesis" (they’re avoiding us), "rare Earth hypothesis" (we’re unique), technological extinction, or civilizations being too far apart.
• The possibility that we’re missing signals or that advanced life transcends exploration altogether.
• Quote:

  “Even if life is abundant in the universe, intelligent life able to exit its planet of origin is something truly exceptional… and that would explain why no trace of extraterrestrial intelligence can be found.” — Thomas (48:18)

Celestial Endings and Transformations

Timestamps: 51:11 – End

• Final approach to Andromeda’s center, with descriptions of the galactic bulge and supermassive black holes.
• Speculation on the far-future collision of Andromeda and the Milky Way and the unknown universe to follow.
• Gentle, dreamy conclusion: Encouraging listeners to "take a deep breath" and drift toward sleep.
• Quote:

  "We are now approaching the end of our galactic journey. It is time to start the return trip to Earth and to fall asleep when you are ready. So take a deep breath in and back out. Allow yourself to drift off." — Thomas (52:31)

Notable Quotes & Memorable Moments

• On the scale of the cosmos:

  "We are far too small and slow to even imagine reaching the edges of the Milky Way, let alone traveling to another galaxy… When we look at the sky and see Andromeda, what we're actually seeing are rays of light that the galaxy emitted two and a half million years ago." — Thomas (10:44)

• On cosmic humility:

  "Maybe in the future an explanation of this mystery will emerge. But in the meantime, it reminds us of just how little we know about the universe." — Thomas (40:36)

• On the dream of space travel:

  "By the power of imagination, we'll be traveling to space. We're going to accelerate to several thousand times the speed of light until we reach the distant Andromeda galaxy." — Thomas (02:35)
