What about all the other wars in American history? Many of the Indian Wars lasted decades, says Don Surber in the Charleston, W.V., Daily Mail. The Second Seminole War lasted from 1835 until 1842, and the Sioux Wars lasted from 1854 to 1890. Also, he says, in the case of Afghanistan our enemy struck first.
Special relativity is perhaps one of the least intuitive theories ever conceived in the history of science, yet it is central to physics. In E = mc 2 Einstein concluded that mass (m) and kinetic energy (E) are equal, since the speed of light (c 2) is constant. In other words, mass can be changed into energy, and energy can be changed into mass.
So what we call the laws of physics (how matter and energy behave in our universe) would not be the same in some other bubble universe. One of the ideas that Albert Einstein put forth is that what we think of as space is determined by the presence of matter and energy.
