Unsolved mysteries, can you solve them?

There are mysteries all around the world. I have ideas for some, but here are the mysteries that none have managed to solve: 

1. What controls the brain?  

2. What created matter in the first place? 

3. Who made human's body design? 

4. If the universe collapses/explodes/disintergrates, will a second universe appear? 

for question 4, will universes last forever if the cycle I mentioned above apply's?  

For anybody that can give a good explanation, please reply in comments.

Obama

My comments about Obama: 

Obama is a strikingly smart and determined person. In my mind, he certainly will bring change to America. Since the whole continent is in financial turmoil, he has a very daunting task ahead. I suggest that the most important industry in the path of destruction, which the situation looks like a steamroller heading for an ant, is the auto-industry. The problem with American people is they were hugging onto large, oil-hungry cars and, even as prices for oil are getting out of control, still keep to the same transport. Here are the main problems Obama has to solve:

1. Tell the people of America "use transport that are more eco-freindly, like trains and electric powered cars" 

2. Join with Hillary Clinton, so decisions are more accurate (different opinions put together make a better outcome) 

3. Give Sarah Palin a job of Secretary for Animal Killing, at least it gets rid of household pests

4. Change the world

I support Obama. Remember this one small phrase can have a whole new meaning:
