  • 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.

    Seems like someone just pirated these from YouTube — ads and all.

  • Horrible editing

    Jarring, loud ads in the middle of sentences frequently. At least let him finish his sentence.

Talking Points

Recent interactions between the hosts and their guests.

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.
The Nature of Space and Time AMA
Q: Does the expansion of the universe imply that space is expanding into something, or is it that space itself is being created and stretched within its own boundary?
The expansion is better thought of as the growth of space itself within the universe's own boundary, not expansion into pre-existing space, with the scale factor increasing and galaxies appearing to move apart due to the stretching of the spacetime grid.
The Nature of Space and Time AMA
Q: Simply, what is the nature of time?
Time emerges from how systems evolve and how entanglement among particles grows; the arrow of time is tied to entropy increase and memory formation, while the fundamental laws are time-symmetric, making our experience of time a consequence of initial conditions and information flow.
Where Is The Center of The Universe?
Q: Does chirality depend on the observer's frame of reference, and what happens if you accelerate to overtake a particle?
Chirality is Lorentz invariant and does not change with frame, although helicity can flip depending on the observer's motion; this distinction explains interactions with the weak force.
