A guest post by Alice in Wonderland

Hi, I’m Alice. I wonder about stuff. Like why it’s dark at night; or why we can’t walk through walls; or why, when we jump up, we don’t just float out into space. I’m pretty sure my brother Bob (he’s older than me) thinks I’m crazy sometimes. But I think we’ve figured out some pretty cool things about the world. Just by looking around and thinking a bit. Like the “dark at night” thing: I think it means the universe hasn’t been around forever – that it actually had a beginning. That’s just freaky! The universe is so amazing! I have to tell you, things are not always what they seem, and it gets pretty intense sometimes. Anyway, me and Bob have videotaped some of our crazy “thought experiment” adventures.
