  • Great except for ads

    I absolutely love this show and it’s perfect for a podcast but the frequent, loud, sudden ads make it almost unusable for now

  • Ads Are Startling

    I love PBS Space Time, but the ads make this podcast borderline unlistenable for me. I have jumped out of my seat from how loud and sudden they are.

  • Worst commercial breaks

    I’m grateful for podcasts that share material like that shared through this channel, but the frequent commercial breaks that interrupt dense content mid sentence ruin this show for me. It’s as if PBS has no editorial influence on where these breaks occur or how long they are, and whomever the choice is left up to is intentionally attempting to ruin the episodes. Please improve this. It wouldn’t be too hard. Sentences end. Content areas have subdivisions. Put the commercials in places that don’t ... more

  • Great but annoying adverts

    The science and presenter are both great and informative. However, mid sentence an ad pops in totally destroying the flow. Good content marred by very poorly placed advertisements.

Talking Points

Recent interactions between the hosts and their guests.

Will You Travel to Space?
Q: What motivates Branson personally to pursue spaceflight?
Branson states that his motivation comes from the desire to build the spaceship and to share the vision of space access with the public, framing it as a bold, almost aspirational mission rather than purely a business venture.
Will You Travel to Space?
Q: Why is space tourism seen as the initial commercial approach by Virgin Galactic?
The guest explains that while the broader dream is long-term space exploration, starting with space tourism allows them to scale, test air-launch technology, and progressively reduce costs so more people can participate, while funding further development.
How To Detect a Neutrino
Q: Don, could you explain how DUNE will actually work and what it hopes to measure?
DUNE will generate a super intense neutrino beam at Fermilab, shoot it through the Earth over about 1,300 kilometers, and detect the neutrinos in a large argon-filled detector deep underground in South Dakota to study oscillations and differences between matter and antimatter.
How Stars Destroy Each Other
Q: How can we know that a black hole isn't just a neutron star behind an event horizon?
By considering how the event horizon and spacetime geometry behave under extreme gravity, and by looking for signatures like the presence or absence of a surface, as well as gravitational waves and accretion dynamics that align with black-hole predictions rather than a neutron star.
How An Extreme New Star Could Change All Cosmology
Q: What makes ZTF J1901-1458 so unusual compared to typical white dwarfs?
It spins every seven minutes and hosts magnetic fields around a billion times stronger than Earth's, which is far more extreme than standard white dwarf scenarios and hints at a possible merger origin.
