Testing Gravity and Dark Matter

Co-host David Livingston and cosmologist Patricio Gallardo explore the Cosmic Microwave Background to see if the laws of physics hold up across the universe.

David Livingston of The Space Show, my colleague, co-host, and copilot is here.

However, inside this, there are a number of mysteries that have come up over the last 100 years. And one of them is, are there special rules for big structures? I mean, really big.

Patricio used the Atacama Cosmology Telescope in the Atacama desert in Chile for his work and it's published in the Physical Review Letters. What was the problem you were addressing with your work and what was the solution?
