It started out as a kiss, how did it end up like this?
Thursday was an interesting day. Before the pub scene which took its toll on me, there was an honours information session at uni. Most of the honours projects available look extremely complicated however I'm sure the supervisors will step us through whats going on, at least to an extent. It's kind of exciting that we get an office too. Im not sure how many people have to share an office but yeh... How cool.
Also I'm not sure wether or not to take second semester next year off after I finish my degree in june. Or to start honours with the project first instead of the coursework. Which might be quite difficult...
Currently the prospect of going overseas is winning. I have a cousin in america and lots of family in scotland. I'm told you can get a round-the-world ticket for like 2.5 thousand and a return trip to europe alone is like 2k so might as well just go to the U.S. for a month or two then maybe stop somewhere interesting on the way and end up in scotland where I can get a crappy car off of my uncle hopefully and drive about europe. But then again this is all just a dream atm. It's both exciting and scary. 7 months overseas living in backpacker inns and hopefully staying with family a little bit here and there, working in pubs or something.
So as I was saying thursday was quite interesting, because thursday night I ended up quite drunk. Was a really good night. Darren was trying to set me up with some chick who he said was looking at me. Which I did end up talking to her for a little while until heather scared her off... Though she was too attractive to be talking to me she probably was just waiting for me to offer to buy her a drink. Although I wasn't in my flirty drunk mood, I was still shy. :( I also saw rach and co. there, thats something I haven't seen for a while. haha and rach was drunk, thats something thats even rarer to see :P. Ended up hanging out with darrens freind daniel again (not sure if I mentioned here last time I was pissed with him) but anyways he ended up picking up some chick and then her freind decided that she gets to follow me around because my freind hooked up with hers it seems. And she was trying to get me drunk :S. Maybe if she was hot I wouldnt have minded :P. There was actually quite a few chicks there last night, although not towards the end. Some chick thought I was hitting on her because I stupidly asked where I knew her from :S so she told me she had a kid or a boyfreind or both or something and I was like so... oh yeh that came across wrong and then had to try to make myself look less stupid. Don't think it worked.
As per usual I have to do something so I have to end the post here. Had something intelligent to say too but that can wait til later
[EDIT]
Alright I'm back, and as promised I have something quasi-intelligent to say. I couldnt sleep last night because a strange thought came into my head that seemed to offer a possible solution to the current dark matter problem. Obviously it can't be as simple as this, but it is indeed an interesting idea. Get this, all forces are said to be mediated by a force carrying particle. Often massless particles otherwise the universe wouldnt really work... Now anyways gravity is theoretically mediated by the graviton, a massless (rest-massless) spin 2 boson. So, taking this into account. Gravitons must clearly have energy which means they must clearly have a mass when they are moving. E=mc^2, energy is mass.... Now that means that the path of gravity can be bent by gravity doesnt it? Which means that gravitons can technicall "fall" (loosely speaking) towards a larger mass, such as the black hole (or equivalent) that in the centre of the galaxy, thus "accelerating" them giving them more energy. Photons exhibit this behaviour. So if a gravitons energy is what accelerates and object towards a massive object a more energetic graviton will appear to have come from a heavier source, thus making the mass in the outer regions of the galaxy behave as if they are heavier.

I'd like to critisize but i dont know enough about the subject :( :P
seems like i've forgotton how to spell critisize too
Criticise. None of your American-style overuse of this so-called letter 'zee'!
As to the topic at hand, it sounds reasonable to me, but I also have insufficient knowledge of the subject. I suspect Ben may be capable of some meaningful input on the topic.
i thought it was with an s there but it didn't look right :S oh well. stupid americans.
Hmm, it's certainly an interesting theory. Though since gravitions aren't incorporated into the standard model of particle physics you might find that you have to solve that problem first :p.
I suppose I have a couple of comments, not nessecarily criticisms. You assume that it's some kind of "graviton wavelength" that determines how strongly two objects feel each others gravity. This sounds pretty good to me, I guess I'm wondering if the same is true of photons. I suppose the wavelength of a photon is related to the momentum it carries and so determines the amount of momentum transfer per quanta of emag force or whatever. Sure, the same could be true for gravity. Still, sounds like you have to solve the grand unified field problem to work it out :p.
I think your looking at it the wrong way around though. Yes the fact that gravity doesn't make much sense to anyone whatsoever. But the wavelength analogy for light is just because the light is given energy from the gravitational potential. More energetic means higher frequency. So it does seem natural that gravitons gain energy in a gravitational field. But yeah, i'm going to have to harrass lecturers about that one next week and have another look at the problem in 2008 with some quantum field theory under my belt :P
Lol, the general relativity might be pretty useful too. You might find it covers that very scenario already.
