Attention
"Did you know" is more polite than "Do you know" here.
This sentence means:
1. It's OK if you didn't know, because I can share the information with you.
2. You might already know, but it doesn't matter because I can still share the information with you and we can talk about it more.
We are talking about sth. that is always or generally true, i.e. facts, so we use the simple present here.
e.g. The teacher said there are 1,440
minutes in a day.
“one of+the+形容词最高级+复数名词”表示在某一范围内“最……的……之一”。
