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.
In physics, a field is a physical quantity that has a value for each point in space and time. For example, on a weather map, the surface wind velocity is described by assigning a vector to each point on a map. Each vector represents the speed and direction of the movement of air at that point. As another example, an electric field can be thought of as a condition in space emanating from an electric charge and extending throughout the whole of space. When a test electric charge is placed in this electric field, the particle accelerates due to a force.
