8.) Kaku says something was both a gift and a curse to humanity. It was this something that provided protection and support for individuals making up early tribes. These tribes would split up when the grew beyond a “critical mass” into two separate tribes, and each would develop its’ own “something” to help promote the unity and security of each of the resulting tribes. It was a curse because it promoted an “us” versus “them” ideologies that caused fierce rivalries and wars between tribes. What is this something?
A.) Shared real estate. They all lived on the same land, which they competed to control.
B.) Intoxicants like alcohol which acted as “social lubricants” making it easier for tribal members to tolerate the idiosyncrasies of other members of the tribe, but raised tempers and so caused fights.
C.) Shared culture and mythology developed while telling heroic myths around the campfire.
D.) Inter-family ties through marriage and other economic bonds.
9.) In addition to the rise of the global economy and the weakening of nations, there is another, equally powerful force that is pushing for stability and a planetary civilization, and this is ______________________________________
A.) culture
B.) the rise of the international middle class
C.) mass media like television shows which help the world population to develop a sense of shared values by displaying world-wide examples of how to behave in situations before you encounter them
D.) a desire for security
10.) Which language has already emerged as the global “Lingua Franca” of science and business?
A.) English
B.) math
C.) Japanese
D.) love
Visions Chapter 16
11.) Ultimately we may learn the answers to some questions about the fabric of space-time, such as
A.) Can space be torn?
B.) Can time be reversed?
C.) How was the universe born and how will it eventually die?
D.) All the above.
12.) “…what is pushing the Earth in its’ orbit around the Sun is space itself.” Who was it that was led to believe that gravity is determined by the geometry of space-time- i.e. that gravity was an illusion caused by the bending of the fabric of space-time.
A.) Isaac Newton
B.) Paul Dirac
C.) Niels Bohr
D.) Albert Einstein
13.) An Einstein-Rosen bridge allows for travel across
A.) a test tube filled with water
B.) any bay, river, lake or body of water
C.) space
D.) space and time
14.) If you go back in time and kill your parents before you were conceived, then your birth is impossible. If you set out to build a time machine, but an elderly version of yourself travels back in time and gives you (the younger version of you) the design for a time machine, then where did the design for the time machine come from? These are examples of time travel paradoxes. The answer to these paradoxes may lie in ________.
A.) the bottom of a box of Cracker Jacks.
B.) quantum theory.
C.) relativity theory
D.) Newtonian mechanics
15.) What is the name of the effect that is used to explain that in quantum theory, a vacuum between two parallel uncharged plates is not empty, but is really “frothing” with electron-antielectron annihilations?
A.) Casimir effect
B.) Hall effect
C.) Uncertainty principle
D.) high school principal

A.) opinions
B.) assumptions
C.) continents
D.) feelings
17.) “…quantum theory gives us the most complete description of the microcosm, the ghostlike world of subatomic particles. The quantum theory is based on the idea that a “force” is created by _________________________.
A.) vortices in the void
B.) complex dynamical systems
C.) the exchange of tiny discrete packets of energy called quanta
D.) a warp in the fabric of space-time
18.) Which theory is the only theory known to science which selects out its own dimension of space and time?
A.) superstring theory
B.) quantum theory
C.) relativity
D.) Newtonian mechanics
19.) Once we quantize the universe, we are necessisarily led to believe that the universe can exist in parallel quantum states. When applied to a universe, it gives us the _______
A.) the cosmos
B.) the implicate order
C.) the implementation of the uncertainty principal
D.) the multiverse
