🎙 Guest: Guadalupe Cañas Herrera, Theoretical Cosmologist and Euclid Consortium Member

The Cosmic Scoop:

What’s driving the universe’s wild expansion? Dark energy and dark matter make up 95% of the cosmos—but we barely understand them. Enter Euclid, launched in July 2023 to map a 3D universe and crack these mysteries. Guadalupe Cañas Herrera, a key player in the mission, takes us 10 billion light-years into the past, challenging Einstein’s gravity and rethinking the “dark” labels we’ve slapped on the unknown. Bonus: she also brings Zumba energy to cosmology.

Quotable Insights:

💡 "We completely messed up in terms of assigning 'dark' to dark energy and dark matter—like, it was a fraud in terms of marketing."

💡 "I prefer to believe that mathematically we’re still not there yet—so we must revisit Einstein’s equations rather than assume some hidden fuel."

💡 "Statistically, it’s so unlikely that we’re alone—we’re on an average planet, in an average galaxy, in an average universe."
