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!
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? I discuss these questions and more in today’s 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? I discuss these questions and more in today’s Ask a Spaceman!
What is the fine structure constant? Where does it come from? Why is it so important? I discuss these questions and more in today’s Ask a Spaceman!
Why do we care about loop quantum gravity? Is it a viable path to uniting quantum mechanics and general relativity? What does it mean for spacetime to be discrete? I discuss these questions and more in today’s Ask a Spaceman!
