In this episode, we'll journey through our home galaxy, the Milky Way, a vast spiral galaxy with over 100 billion stars, including our Sun. Located in the quieter Orion-Cygnus Arm, about 27,000 light-years from the center, our solar system orbits far from the powerful supermassive black hole, Sagittarius A*, which holds the galaxy together. We'll explore the three main types of galaxies—spiral, elliptical, and irregular—and imagine the technology that might one day let us travel beyond the Milky Way. Finally, we'll consider one of science's biggest mysteries: Are we alone in the galaxy? We'll learn how scientists search for life on planets in the "Goldilocks Zone," keeping us curious about what—and who—might be out there.

In this episode, we will answer listener questions that explore how the universe works in fun and surprising ways. We learn that nothing can travel faster than the speed of light and explore what might happen if we could—like time slowing down and strange space effects. We also find out that there are stars much bigger than the Sun, how the Sun spins on its axis and how gravity, though invisible, holds everything in place. We will wrap up by understanding why air remains invisible despite being all around us but can still be felt and experienced in many ways, like wind or when we breathe.
