Virtual reality starts in your head

Even before the invention of computer simulation, we were able to explore the possibilities of intricate concepts, construct alternative realities, and even put our ideas to a test-drive by using thought-experiments. They are the favorite game of philosophers and thinkers, and arguably one of the most crucial parts of both scientific and everyday life. These mental puzzles provide us with significant, otherwise hidden, insights and provoke our imaginations whereby we can expand our knowledge without previous experience.  

Here you will find seven thought-provoking mental experiments that will make you reassess your presumptions about certain topics:
