The theory of relativity holds a certain fascination for many people.
At the same time it is often
regarded as very abstract and difficult to understand.
Part of the difficulties in understanding relativity are due to the
fact that relativistic effects contradict everyday experience. Motion,
for example, is a familiar process and everybody "knows from
experience" that it entails neither time dilation nor length
contraction. A flight with half the speed of light could correct this
misjudgement but is not on offer.
A possible alternative are simulations. Images, films and virtual
reality let us in a sense experience relativistic flights,
gravitational collapse, compact objects and other extreme conditions.
