May 3rd: Should We Be Afraid of the Dipole Repeller?

by Paul M. Sutter | May 3, 2022 | Ask A Spaceman

What is the dipole repeller? Why is it a dipole? What is it repelling? What is the Bootes Void and how is it connected to dark energy?

Apr 19th: What Solves the Twin Paradox?

by Paul M. Sutter | Apr 19, 2022 | Ask A Spaceman

What does everybody think is the twin paradox? What’s the REAL twin paradox? How is the paradox resolved, and what does it teach us about synchronicity? I discuss these questions and more in today’s Ask a Spaceman!

Apr 5th: How Does Radioactive Decay Work?

by Paul M. Sutter | Apr 5, 2022 | Ask A Spaceman

How was radioactive decay discovered? What are the different kinds of decay? How does quantum mechanics make all this happen? I discuss these questions and more in today’s Ask a Spaceman!

Mar 15th: What Are Some Alternatives to the Big Bang Theory?

by Paul M. Sutter | Mar 15, 2022 | Ask A Spaceman

What makes the Big Bang theory so successful? How were alternatives ruled out? What are the electric universe and steady state theories? Do any other options remain, like conformal cyclic cosmology?

Mar 1st: What are Lagrange Points?

by Paul M. Sutter | Mar 1, 2022 | Ask A Spaceman

Why are Lagrange points so crucial to astronomy? What makes even simple gravity so difficult? How do you “put” something at a Lagrange point?

Feb 15th: What’s So Fine About the Fine Structure Constant?

by Paul M. Sutter | Feb 15, 2022 | Ask A Spaceman
