,1,Are we rethinking the Big Bang? On this explainer, Neil deGrasse Tyson and comic co-host Chuck Nice break down Big Bang skepticism and what’s going on at the frontier of astrophysics.
What are the core tenets of the Big Bang Theory? We explore the frontier of scientific research and what ideas are being contested. We also walk through the scientific process and experimentations. Could the Big Bang just be a small piece of a bigger theory? Learn about Vulcan, the hypothetical planet pulling on Mercury that was invented to save Newton’s Laws. When Einstein’s relativity came along, why didn’t Newtonian physics go away?

,1,We all know about Earth’s magnetic field, right? Well, Neil deGrasse Tyson and comic co-host Chuck Nice are here with another StarTalk Radio explainer to fill you in on the things you might not know about Earth’s magnetic field and magnetic poles.
Find out why Earth’s south magnetic pole is actually in the North. We discuss how Earth’s magnetic field is not aligned with Earth’s rotation axis. You’ll discover why when you use a compass to find North it’s most likely pointing to somewhere in northwest Canada.
You’ll learn about the differences between Earth’s magnetic poles vs. Earth’s geographic poles. Neil tells us how to actually find true North. Neil also explains why the magnetic poles of the Earth flip and have flipped many times. We discuss the “dynamo theory.” Lastly, we take a look at the Sun’s magnetic field and how that impacts sunspots. All that, plus, Neil tells us why there’s no understanding of magnetic fields without quantum physics.
