The whole "differing laws of physics on different length scales" is interesting.
If you press the button to double gravity in a different place then you can get different orbits. Feel free to experiment with it here:http://dl.dropbox.com/u/6934906/Gravitation.swfI was lazy and didn't make any functionality to restart the program so you'll have to reload it every time you want to try a different thing
OH SHI...http://uk.news.yahoo.com/18/20110407/tsc-us-atom-smasher-may-have-found-new-f-e123fef.htmlhttp://www.tgdaily.com/general-sciences-features/55233-tevatron-data-indicates-unknown-new-particleScientific Paper : http://xxx.lanl.gov/PS_cache/arxiv/pdf/1104/1104.0699v1.pdfBasically though the particle accelerator has found a signal that looks like a new, unknown, type of particle. The small blue peak on the right graph is the signal that is raising interest. It has a statistical significance of 3.2 sigma according to the paperGoogle calculator says 3.2 sigma = 0.998625724 = 99.86% accuracy - so a 0.14 chance of being a random error due to statistical fluctuations.There is also a chance that there was an error in the modelling of the system or some kind of mistake in our understanding of particle physics, but the scientists at the Tevatron have said they are certain it is not an equipment glitch apparently. There will be a few more months of analysis, to see if this anomaly is the result of a flawed model or a misunderstanding (and that the anomaly is not an anomaly at all) but if not, then the basic system of particle physics, the standard model, is about to be turned on it's head.
