The conversation between human and AI assistant.
Why does it take 20,000 years for light to reach the surface of the Sun from its core, but just 8 minutes to reach the surface of the Earth?
Wow, that's really interesting. Are there any other factors that can affect the speed of light?
Yes, the speed of light can be affected by the medium through which it is traveling. For example, light travels slower through water or glass than it does through a vacuum.
