Could you please explain this sentence?

Light zips along at the actual “speed of light”, faster than which nothing can go, only when it is travelling through a vacuum.

I don't quite understand the "faster than which nothing can go" part. Thank you.

So my interpretation of the sentence is "only when light is travelling through a vaccum that nothing can be faster than it". Is that correct? Thank you.

Hi,

So my interpretation of the sentence is "only when light is travelling through a vaccum that nothing can be faster than it". Is that correct?

No, not really. Here's how I see the meaning.

Light zips along at the actual “speed of light” only when it is travelling through a vacuum.

By the way, nothing can go faster than the actual speed of light.
