Millionaires are Baby Boomers (or Older) For most Americans, incomes tend to rise with age and experience. Thus, it is not surprising that in 2009, 80 percent of millionaires were older than age 45 and close to half of all millionaires (46 percent) were older than age 55.
Theory. A scientific theory summarizes a hypothesis or group of hypotheses that have been supported with repeated testing. A theory is valid as long as there is no evidence to dispute it. Therefore, theories can be disproven.
Outside of science, the definition of a theory is a thought that may or may not be true. In the science community, a scientific theory is defined as a hypothesis or a group of hypotheses about some phenomena that have been supported through research using the scientific method.
