Einstein’s theories of relativity have fundamentally changed the way scientists view reality. This bothers some, which is why you can find creationists who desperately try to fight against them. These attacks often strike a chord since most people (even many scientists) know little about these revolutionary theories. Partly, this is because the theories are difficult to understand. In addition, they often deal with things that are not a part of everyday experience, such as extremely high speeds or unusual gravitational fields. Nevertheless, both theories are immensely important to some everyday items. For example, if you use a GPS device for navigation, that device would not work properly if the global positioning system did not use relativity correctly.
To understand what I mean, you first need to know that Einstein proposed two separate theories of relativity. Special relativity deals with systems that move relative to one another with a constant velocity. General relativity deals with systems that move relative to one another with a variable velocity. In each theory, Einstein’s only concern is that the laws of physics must work the same in both systems, regardless of the fact that they are moving relative to one another. While this seems like a common-sense idea, it leads to conclusions that make little sense.
