  • Good, but could be better

    It is a good show, but the negativity against the idea of god is very displeasing and intrusive.

Talking Points

Recent interactions between the hosts and their guests.

Cosmic Queries – Total Darkness
Q: What would you propose to maximize humanity's telescope capabilities with global budgets?
An array of telescopes on the far side of the Moon, spanning all electromagnetic windows to avoid Earth's radio noise and clouds, enabling observations across the spectrum including gravitational waves and neutrinos that aren't strictly electromagnetic.
Exploring Hidden Dimensions with Brian Greene
Q: What is the current state of string theory, and why hasn't it made a testable prediction yet?
String theory has yielded deep theoretical insights and mathematics, notably in black holes and quantum gravity, but it has not yet produced a testable prediction at accessible energy scales, so its status is healthy but not conclusively proven.
Told You So! with Matt Kaplan
Q: When did science begin to tear free from religious or established authority, and what does that mean for modern science?
It started with figures like Galileo during the Renaissance, who used observation and reason to challenge accepted beliefs, establishing a model where evidence guides conclusions even when it clashes with authority.
Cosmic Queries – Origins of the Universe, with Janna Levin
Q: What is string theory in two sentences?
In the microscopic universe, fundamental particles may actually be tiny loops of string, vibrating in different harmonics; those harmonics give rise to different particles, so all matter and forces may be manifestations of one fundamental string.
Cosmic Queries – Gravitons & Hyperspeed
Q: If galaxies are moving apart due to cosmic expansion, how will the Milky Way and Andromeda collide in the near future?
Nearby galaxies feel each other's gravity despite the universal expansion, so they can collide; Andromeda will likely collide with the Milky Way in about seven billion years due to their mutual gravitational attraction overcoming the expansion at that scale.
