  • Please run Chuck

    Neil said it as a joke, but please run for congress Chuck. We desperately need people just like you. People who respect science and also understand real everyday life. People who are smart and can still learn new things. People who can talk passionately with righteous anger… Please run.

    Also, I enjoy the show too.

  • Laughing talking

    I’ve always wondered, do people really enjoy hearing people laugh constantly? And also talking over one another? Interrupting one another? I mean laughter is OK but this is over the top. I can’t listen to it. I know the guy is an astrophysicist and a brilliant person. If he could just be a little more eloquent instead of jovial, this would fly better.

Talking Points

Recent interactions between the hosts and their guests.

Bug Splat Galaxies with Mordecai-Mark Mac Low
Q: If Jupiter were made much more massive, could it ignite like a star, and what happens to its rocky core?
Increasing mass can ignite hydrogen fusion at around 80 Jupiter masses, producing a brown dwarf or a very low-mass star, and the rocky core would be assimilated into the hot, fused hydrogen state, effectively vaporized.
Bug Splat Galaxies with Mordecai-Mark Mac Low
Q: Hello Mordecai, how long does it take to form a star or a planet, is it the same process for both?
The main formation phase for stars is on the order of 100,000 years, with planetary formation continuing for a few million years; planets can begin forming early in the disk while the star accretes, and moon-sized bodies can emerge in the same environment.
Is Reality Really Real? With Donald Hoffman
Q: What prediction can your new formulation make that would convince scientists of its validity?
The plan is to show how special and general relativity, as well as quantum field theory, emerge from the trace logic of observers, and then derive the speed of light as a maximum transition time from Markov‑chain dynamics.
Cosmic Queries – LIGO, Light, & Lycanthropy
Q: Is there evidence that full moons affect neurological events or birth rates, or is it primarily a perception issue?
Current evidence does not support a causal link; observed correlations are typically explained by cognitive biases and misattribution, while tidal forces from the Moon do not depend on phase and have minimal differential impact on biology.
Cosmic Queries – LIGO, Light, & Lycanthropy
Q: Why is LIGO able to detect gravitational waves when there is no accompanying light signal, and how was verification achieved?
LIGO detects spacetime distortions via interferometry rather than light; verification came from matching the gravitational-wave signal with expected waveforms and, in some cases, coincident observations across multiple detectors, and targeted electromagnetic follow-ups when possible.
