Dark Matter, Spacetime's Expansion, & String Theory with Neil deGrasse Tyson - Cosmic Queries
Summary

In this episode of Star Talk Cosmic Queries, the host Neil deGrasse Tyson and co-host Jordan Klepper answer questions from Patreon supporters. They discuss string theory and its attempt to unify quantum physics and Einstein's general theory of relativity. They also talk about the formation of our solar system and how planet migration is a normal process that can force readjustments to create a spread of what we see in our catalogs of star systems. Tyson recommends checking out the Star Talk Cosmic Queries book for more information on the formation of star systems and the migratory process.

The hosts also discuss the expanding universe, dark matter, and non-interacting phenomena. They speculate that dark matter could be a class of particles that do not interact with our own particle family but still have mass and gravity. They talk about the concept of emergence and how consciousness and dark energy could be emergent properties of complex systems. They also explore the potential for developing dark matter vision goggles in outer space.

The episode is informative and humorous, with the hosts making jokes and pop culture references throughout. They also discuss the evolution of car antennas and how they have become smaller due to the shift towards using microwaves for communication. The hosts address a listener's question about what we would see if we traveled at the speed of light and explain how science works across space and time to understand the universe. The episode ends with a humorous exchange about mispronouncing the host's name and bidding listeners to keep looking up.
