S3E3 Light Speed

Physics tells us that traveling faster than light is impossible... or is it? At light speed, we can witness events on Earth in real-time while also glimpsing the universe's history stretching back nearly 14 billion years. Dive into the concept of light speed, the universe's ultimate constant, and explore the innovative ideas scientists have about potentially overcoming the "light barrier." This breakthrough could be the key to turning our dreams of interstellar travel into a tangible reality.
