In this typical online chat program, the window to the left shows a list of contacts, and the window to the right shows a conversation between the user and one of those contacts. Online chat may refer to any kind of communication over the Internet that offers a real-time transmission of text messages from sender to receiver. Chat messages are generally short in order to enable other participants to respond quickly. Thereby, a feeling similar to a spoken conversation is created, which distinguishes chatting from other text-based online communication forms such as Internet forums and email.
Limitations of the Scientific Method. The scientific method is limited to those phenomena which can be observed or measured. For example, what existed prior to the Big Bang and the known universe is outside of the realm of science to investigate.
The scientific method is a process for experimentation that is used to explore observations and answer questions. Does this mean all scientists follow exactly this process? No. Some areas of science can be more easily tested than others.
