What I think happens upon death

Easy.
Everyone goes to a lovely dream world where they get to do whatever they please! We visit that world several times a night, but we don't get to stay there. People in comas sort of visit it, but not fully. When you die, you get to live and control it, and you can go visit your friends by thinking about a door in a hallway. The hallway is in fact just a cloud in an endless sky of clouds, and you instantly know how to get to your friend. And you can't fall.
Of course, there's a world that everyone hangs out in, and they only go in their own world if they want to have private fantasies. The main area everyone hangs around in is a bit like Second Life, in that people work together to do what they want.
You can also instantly find any dead person you like. You can go visit living people, but unless you try really hard, you can't have any effect on them. The easiest things you can do is transmit emotions e.g. approval of a new spouse, or love.
If you're a fundementally bad person, you get locked into your room, although if enough good people decide to unlock it, they're allowed out.
Oh, and Vlad, thanks for the first comment. :3

CERN et al

Well, we all died a horrid death on Wednesday when CERN's LHC made a black hole and killed us all.
Sorry, I just didn't want to start with "Well, CERN didn't kill us all on Wednesday", since I imagine every blog in the entire world probably started with that. Still, I shouldn't tempt fate; the LHC doesn't just "start", the scientists do all sorts of experiments.
Not that that matters; cosmic rays create high energy collisions up in the atmosphere. The most convincing argument I heard was an emotive argument, however:

"We all have families too, and we don't want them to die either."

Also "Spaghettification" is now my new favourite word.
The A Level Work load is quite tough, but I think I'm dealing with it. I had a strange dream this morning where instead of doing homework, I snuck out and bought a microwaveable bacon bap, and got drunk off it, then arrive in school in nothing but a cardigan. Odd, eh?

My first week of A-Levels

Just in case I haven't mentioned it, I'm taking:

French

English Literature

Biology

Chemistry

Critical Thinking

I didn't pick Critical Thinking; the school makes us take it, as it's desired by Universities. From what I've seen of it, it's really enjoyable - I love debating (I've been on the junior debate team for all three years, and we won twice! I'm always seconder) and this is pretty much that. It's only a double period once a week, but it's still good!
There's no longer any single lessons, but now I've got free periods! Well, study periods. You have to work. But that's ok - there's plenty to do! I have to copy up and expand my notes for every subject, so I'm keeping on top of it.
A levels are completely different. There's a much better rapport with teachers - in French, the majority of the lessons so far have just been chatting in French! Biology and Chemistry are really interesting; at the moment it's mostly expanding on what we already know, but it's engaging.
English Literature is wonderful. We get to critically analyse texts, and I've learned so much. For example, there's a school of thought based on Roland Barthes' Death of the Author essay that says that it's the reader's interpretation that matters, no matter what the author intended. I think it's a bit much, but it basically means that since authors are shaped by what they see and read, anything you read into the story could have been put there by the author subconciously.
I've been reading a lot of Banana Yoshimoto; have I said before that "Kitchen" is probably one of my favourite books ever? I'm also trying to learn spoken Japanese; I can say "Good morning", "Pleased to meet you", "My name is Arex Shirfiedu" (That's adjusted for Japanese tounges) as well as many words like "coat", "bed" and how to phrase a question. According to the three Japaenese speakers at my school, my pronounciation is good. Japanese is a tonal language; you can't stress syllables (so it's not America, but Ah-mare-eek-ah) so you have to change intonation. So Eigo and Eigo sound the same (except for the inflection at the end of the word) but one is a name and one means "English".
