What else can I help you with?
Why are theories modified but rarely discarded?
Most probably because the original theories are based on a certain amount of truth. Now a days, theories are not accepted until there is a significant amount of evidence to back it up. If there should be new evidence that states otherwise, then the theory will be modified. Of course, this is not a black and white situation. Not all theories have been "modified." Some have been completely discarded when solid facts have proved otherwise. For example, the Flat Earth Theory and the theory that the Earth is the centre of the universe.
What may cause a future theory to be revised or discarded?
prediction
Why vital force theory is finally discarded?
The vital force theory was a theory presented by Berzelius. The 1809 theory stated that organic compounds could not be synthesized in a laboratory. The German Scientist contradicted the theory, and prepared Urea through Ammonium Chloride and Potassium Cyanate so eventually is was discarded.

What is the result when a scientist gains new information about a theory?
The theory is modified.
Can the future cause a theory to be revised or discarded?
Yes, new evidence or developments in the future can cause a scientific theory to be revised or even discarded. As our understanding of the world grows and advances, theories must evolve to fit the new information. This process is a fundamental part of the scientific method.
What has to happen in order for a scientific theory or law to be modified?
A repeatable experiment proving the modified theory has to be documented and repeated...generally by multiple labs.
Can a theory ever be disproved If so what happens to the original theory?
Certainly. Many theories are disproved. A disproved theory will either be reworked based on the information obtained while disproving it or will be discarded.
How can scientific theory change?
If new evidence or observations falsify a scientific theory, the theory must be changed to adapt to the new data or discarded altogether. The discoverer of the falsification usually publishes his or her results in a peer-reviewed scientific journal, through which the information is presented to the scientific community. Theories are not "official," but they instead rely on consensus and an understanding of the evidence involved and the scientific method. Usually, however, since a hypothesis must be tested rigorously in order to be accepted as theory, the existing theory needs only to be modified or expanded, and not discarded entirely.
If a hypothesis does not agree with the experiment designed to confirm it what two choices do you have?
The incorrect hypothesis may be discarded, or it can be modified until it is consistent with all the data that has been collected.
What could cause a theory to be modified?
if someone finds a loop hole in the experiment
What would happen if correct new evidence was discovered that did not agree with a well established scientific theory?
The theory would be modified or replaced.
