To me, this is an interesting topic. Could discovering the secrets of dark matter eventually lead us to the secret of how to transport ourselves through time?

I am going to be moving from California to Gainesville, Fl next year. I am buying a house there and I am very concerned about hurricanes. I am worried that if I buy a house, there is a good chance it will be destroyed/damaged. Could you please tell me if it is a real problem over there or whether it is all exaggerated.
Thanks

I can't figure out how to fix this. When I punch in an equation it makes it bigger. I just want the answer. Also if I punch in sqrt(30) it says the answer is sqrt(30). If I punch in PI2 it gives me PI2.

How do I get it to give me numbers?

If I am of sound mind, and a relative calls an ambulance for me, I am taken to the ER with a life-threatening condition, the relative demands I be treated, but I refuse to sign for it or give my consent (and I am totally conscious) -- will they refuse to treat me?

I work at a gene splicing/cloning lab, and my friend brought in some amber with some prehistoric animal hide in it. As a joke, we had been messing around with it after hours. Anyways, where would be a good place to hide a 2 story Tyrannosaurus Rex for a couple of weeks when my boss gets back from vacation?
