We want to understand how the Universe works,<br />
so we look at the pieces that make it up.<br />

Here are questions that I got from the students<br />
If you collide protons & neutrons, can they stick together?<br />
If you fall in a black hole, can you see backwards in time?<br />
If you throw a ball up & it goes forever, where does it end up?<br />
How do black holes evaporate?<br />
How much does it cost (from the teacher)?<br />
What happened before the Big Bang?<br />
Canʼt you take apart the proton to study it without smashing them?<br />
Have I met Stephen Hawking?<br />
Is it dangerous when the collisions occur?<br />
Can we explain why we are the only Earth we know of?<br />
