Chapter nine was a confusing chapter because it was mostly about the eleventh dimension which for me, it is hard to even believe there are eleven dimensions.

Part of this chapter focused on measuring the eleventh dimension. To do so, physicists needed to find a deviation from Newton’s inverse square law at very tiny distances. Physicist knew that this formula worked tremendously at big differences, but if, at small distances there was a deviation, there would have to exist another dimension to throw off this formula. When physicists are measuring at “small” distances, they mean really small. Physicists at Purdue University are bring a sheet of nickel 58 and nickel 64 together until there are separated by atomic distances. We can then attribute any tiny oscillations to gravity because they would become attracted to each other. By measure oscillations they will test Newton’s inverse square and see if there are any deviations.

This chapter then veers off onto another subject atomically small. We know that there is about a billion dark matter particles that fly through every square meter of our world every second. So why then, is it so hard to detect these particles? This is because they interact so weakly with matter. Our machines cannot detect all this dark matter, and if one day in the near future, a machine detects the dark matter, it is said that this may go down in one of the greatest accomplishments of the 21st century.

For all you fellow bloggers, I am wondering, do you think that there really is eleven dimensions in our universe? And do you think that we will be able to find dark matter in this dimensions any time in the near future?
