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.

Sleep Tight!,
