Are all theories always completely accepted or completely rejected?

Fact supported theories and not guesses, but reliable accounts of the real world. Most theories accepted by scientists have been repeatedly tested by experiments and thus can be used to make predictions, which are then most likely to be true


Why can an accepted hypothesis be rejected at a later date?

The answer to the question why is this: It can be rejected at a later date because it is falsifiable in nature if it is a good hypothesis. If you meant to ask HOW it can be rejected, the answer is by way of further experimentation that rules out some or all of the hypothesis as stated.


Are scientific laws and scientific theories the same?

No, scientific Laws and scientific theories are not same.Scientific Laws have proofs, they are acceptable by all like Newton's Laws of motion are accepted by allwhere as scientific theories demands proofs, these are not acceptable by all Like Theory by Charles Darwin is not acceptable by all


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.


Why are hypothesis never accepted by scientist?

Hypotheses are ideas which are, as yet, unsupported by evidence. As a hypothesis becomes backed up by mathematical formulae and observational data, it may, if it is sound, become a theory. All scientific theories began life as hypotheses, it is merely a case of which hypotheses become theories, and which fall down by the wayside after being discredited or having lacked support.

Are all theories accepted or rejected?

No, not all theories are accepted or rejected. The acceptance or rejection of a theory depends on the evidence supporting it, how well it explains a phenomenon, and its ability to make accurate predictions. Some theories are widely accepted, while others may be rejected or revised based on new evidence or alternative explanations.


What is true hypothesis are rarely rejected as false a theory is basically the same as a hypothesis therios are ideas accepted as most likely true all scientific studies are share?

Theories are ideas accepted as most likely true. Theories are basically hypotheses which have been tested many times by many people and are found to be true.


What year was it that people still believed in Galens theories?

Galen's theories were widely accepted until the 16th century. Between the 16th century and the 19th century, there was a period of time referred to as the medical revolution, which saw the emergence of modern medicine. During this time, Galen's theories were no longer accepted as the standard for medical practice. However, some of his ideas, such as the four humors, the role of the liver, and the heart as the center of life, were still accepted as valid, and these theories were used to explain medical phenomena. It was not until the 19th century, when advances in science and technology allowed for the development of modern medical practices, that Galen's theories were completely rejected.Galen's theories were still believed and accepted by the medical community up until the 16th century. During this time, his ideas were heavily relied on to explain and understand medical phenomena, and were seen as the standard for medical practice. Among his many theories, the four humors, the role of the liver, and the heart as the center of life were all accepted as valid. Some of Galen's theories were still accepted and practiced even after the 16th century. However, with the rise of modern medicine in the 19th century, his theories were eventually rejected and replaced with more scientific approaches. This marked the end of the medical revolution, and Galen's theories were no longer accepted as the standard for medical practice.

What do scientists call theories that explain all the evidence?

Scientists call theories that explain all the evidence and are widely accepted by the scientific community "well-established theories" or "well-supported theories." These theories are based on a large body of evidence and have withstood rigorous testing and scrutiny.


Can the Irish army reject you if youre Northern Irish?

How many people are rejected by Cornell?

I found this question in the World War 2 question pool. I guess you wanted to know how many people are rejected by Cornell. It depends on how many people apply that determines the amount rejected by the university. All universities have so many open slots for new students or returning students. So you take this formula: All applicants less those accepted in the allotted amount = those who were not accepted into the slotted amount. Now some applicants are rejected because they do not qualify but most are not accepted because there were not enough available slots.

Why does the Big Bang theory is the most accepted of those theories?

Because at the moment it fits with the facts we know. Theories change all the time as new evidence is uncovered or physics we knew nothing about are discovered.
