But in a spacecraft moving at the speed of light, the frequency of light would be shifted so dramatically that it would fall outside the visible spectrum, meaning the astronauts onboard wouldn't see any starlight at all. Instead, Cosmic Microwave Background—radiation left behind after the Big Bang—would be shifted into the visible spectrum.

Only 10 AM and surely the most interesting thing I will learn today.

I know! Maybe I should have posted this later in the day. If you want to learn more about starlight and the Cosmic Microwave Background, Minute Physics made an amazing video about it. Maybe wait until noon?
