Chapter 17: Wrapped and Warped

Extra Dimensions of Space

When we perceive our Universe, we perceive it as being three-dimensional, however, we must consider that there are more than three dimensions. It is possible that certain dimensions are hiding. We can add another dimension to our Universe. We cannot interpret this extra dimension because from where we stand, we cannot see it. Every point in our three-dimensional space has an invisible dimension. This new idea was proposed by Theodor Kaluza and Oskar Klein and has been very influential in developing the current cosmological model. They proposed that the electromagnetic force arose like gravity, as a deformation of space-time. They postulated that the electromagnetic force resulted from the warping of the fourth-dimension. The third-dimension was warped by mass and energy, and Kaluza and Klein postulated that charge affected the fourth dimension.

  1. Ali, I like the chapter about our universe as something that is never ending. As most people see, the universe can only be as far as we can prove, but there must be more up there.
    As the Hubble satelite grows old, it will be comming down only to be replaced by newer and more advanced technology.
    As the randomness in our universe is increasing, it allows for even more galazies to form.
    I like how you wrote it in words all readers could understand even though they wouldn't understand your book.
    good work!
