Does Space Ever End? | The Sleepy Scientist

📚 I'm really excited to finally share this with you. Quantum Physics, Explained Clearly takes many of the ideas we've explored on the channel and gives them a little more room to breathe. It includes both the ebook and the full narrated audiobook. 🔗 https://www.thesleepyscientist.com/ Does space have an edge, or does it just keep going forever? 🌌 In this calm Sleepy Scientist journey, we follow one of the strangest questions in cosmology. It starts with a single distinction: the observable universe is limited by the speed of light and the age of the cosmos, but the total universe may stretch far beyond anything a telescope will ever catch. 🔭 Along the way we clear up the famous misunderstandings. Why the Big Bang was not an explosion into empty space. Why the cosmic microwave background is not a wall. And how something can be finite yet have no edge at all, the way Earth's surface has no final step. ✨
