The Star Spot

Feature Guest: Jim Cline

Dark matter. Dark energy. String theory. At the frontiers of fundamental physics science seems confronted with mystery and progress is grinding to a halt. But can studying the early universe provide the answer? To help answer that question we're joined at The Star Spot by Jim Cline. We’ll dive into esoteric concepts like string cosmology and cosmic strings, lumps of massively energetic space time fault lines left theorized to be left over from the Big Bang.

About Our Guest


Jim Cline is professor of theoretical and particle cosmology at McGill University. He works at the intersection of cosmology and fundamental physics, studying the cosmic microwave background radiation, dark matter, and particle physics coming out of the large hadron collider. He received his phd from Caltech and performed his postdoc at Ohio State University before joining the faculty at McGill University in Montreal in 1995.

Feature Guest: Gioia Massa

Imagine enjoying a romantic and nutritious picnic - on Mars! If such a dream is ever to be realized, we're going to have to learn how to grow plants in space and on other worlds. Today we're joined at The Star Spot by space biologist and NASA scientist Gioia Massa to discuss the building of a green oasis in space.

Today's news team on all the Red Planet developments:

MOM is on Mars. Dave explains how India became the first nation to successfully reach Mars on its initial attempt with MOM, a mission the budget of which is less than a hollywood Mars blockbuster.

After 2 years Curiosity has arrived at its primary destination: Mount Sharp. Celine gives us a retrospective on the rover's history and shares excitement over upcoming drilling operation in the mountain promised land.

Finally Anuj introduces us to the newest NASA member of the Mars exploration family: MAVEN, an orbiter designed to study how the Martian atmosphere evolved over hundreds of millions of years, seeking to determine whether liquid water was around long enough for life to evolve.
