Wormhole in the sun

"Mum! What does time mean? What is it?"

That's the moment that all parents dread. The moment your child realises that you don't know everything.

But it arrived too early. He was only three.

I started talking about minutes, seconds, hours, days.... He looked at me. That he knew already. Not what he wanted to know.

"But what is it?" he insisted.

Well... errr.... uhmmm...

Thought about bullshitting him briefly. String theory, Einstein, relativity...

I couldn't do it. Pretend that I knew. I answered simply. "I don't know".

Many more philosophical questions have come my way since. At least now, he doesn't expect me to know the answers.
