Yes you can, it is actually very easy to steep them too long. If you leave the tea leaves in the tea too long they begin to release a harsh bitter flavor that no one wants. The best way to make your tea stronger is to add more tea leaves not more time. Below I have listed a small list of the average time it takes to steep each type of tea.
Currently, physicists describe nature as having 4 fundamental forces: the Electromagnetic force, the Strong nuclear force, the Weak nuclear force, and the Gravitational force. At one point in history, the Electric and Magnetic fields were treated as separate. If you count these two fields as separate and add them to the other 3 traditional force fields -- the Gravitational, Strong, and Weak fields -- then, nature might be described as having a total of 5 fundamental fields in Physics.
Topics of metaphysical investigation include existence, objects and their properties, space and time, cause and effect, and possibility. A central branch of metaphysics is ontology, the investigation into the basic categories of being and how they relate to one other. There are two broad conceptions about what world is studied by metaphysics. The strong, first assumes that the objects studied by metaphysics exist independently of any observer, so that the subject is the most fundamental of all sciences.
