Depends on whether all the theory is being contradicted or only a part of theory faces contradiction. For instance; the theory of evolution by natural selection would take a theory shaking hit if we found fossil rabbits in the Cambrian period, which has not happened. Only part of the theory of evolution by natural selection was contradicted by Mendelian genetics, when Mendel's much better heritability mechanism replaced Darwin's idea about blending inheritance. The theory only got stronger by this ratification.
If that new evidence is solid enough, it may require a revision of the theory. If it is just shaky and occurs because of some error in the experiment, it is usually discarded as uncredible.
What else can I help you with?
What makes Darwin's theory of evolution believable?
Darwin's theory of evolution is supported by a vast amount of evidence from various scientific fields, such as biology, genetics, paleontology, and comparative anatomy. The theory is also consistent with observations of natural selection in action, as well as with the fossil record showing gradual changes over time. Additionally, modern research continues to provide new evidence in support of the theory.
How long was it before new evidence emerged to support wegeners theory of the continental drift?
New evidence supporting Alfred Wegener's theory of continental drift began to emerge in the late 1940s and early 1950s, approximately 30 years after he first proposed the theory in 1912. The development of plate tectonics, particularly the discovery of seafloor spreading and paleomagnetism, provided crucial evidence that validated Wegener's ideas. This shift in understanding revolutionized geosciences and established a comprehensive framework for explaining the movement of continents.
What is the reason that a theory might be replaced with a new theory?
a theory is an explanation to a specific question being studied. it has been tested many times. it might be replaced with a new theory because new information come and so the past information will be improved.
How the evidence of the chemical reactions demonstrated bonding theory.?
New compounds are obtained because new chemical bonds are formed.
How did the new evidence support Hess's theory of seafloor spreading?
The new evidence provided observations of magnetic anomalies on the seafloor that were consistent with the pattern predicted by Hess's theory of seafloor spreading. These anomalies demonstrated symmetrical stripes of magnetic polarity on either side of mid-ocean ridges, supporting the idea that new oceanic crust was forming at these ridges and moving away in opposite directions.
If new evidence does not support a scientific theory scientists will most likely?
if new evidence doesn't support a scientific theory, scientists will either revise the theory to accommodate the new evidence or discard the theory altogether in favor of a more accurate explanation. This process is crucial for the progress of science as it ensures that theories are continuously tested and refined to reflect our understanding of the natural world.
How long was it before new evidence emerged to support wegener's original theory?
It took several decades before new evidence emerged to support Wegener's original theory of continental drift. In the 1960s, significant discoveries such as seafloor spreading and plate tectonics provided strong evidence to confirm Wegener's ideas. This eventually led to the widespread acceptance of the theory of plate tectonics in the scientific community.
What happens when new evidence contradicts a scientific theory?
When new evidence contradicts a scientific theory, the scientific community typically evaluates the validity of the evidence and the theory itself. If the evidence is robust and replicable, it may lead to a revision or replacement of the existing theory to better explain the observed phenomena. This process is fundamental to the scientific method, promoting the evolution of knowledge as new information emerges. A theory may not be discarded immediately but rather refined to accommodate new insights.
When was the first concrete evidence found to support the theory that new ocean crust formed at vents in the ocean floor?
1977!
What happens when new evidence disagrees with a theory?
When new evidence disagrees with a theory, it prompts scientists to reevaluate and potentially revise or refute the existing theory. This process is fundamental to the scientific method, as it encourages critical analysis and rigorous testing of ideas. If the evidence is robust and reproducible, it may lead to the development of a new theory that better explains the observed phenomena. Ultimately, this iterative process advances scientific knowledge and understanding.
How do scientists know that a new theory is accurate?
Because all of the observations and evidence are used for support.
What happens when an experiment with new information or new technology produces results that support an existing theory?
When an experiment with new information or technology produces results that support an existing theory, it reinforces the validity of that theory, providing additional evidence for its acceptance within the scientific community. This can lead to increased confidence in the theory and may prompt further research to explore its implications or applications. Additionally, such results can help integrate the new technology or information into established scientific frameworks, facilitating advancements in the field. Ultimately, it contributes to the cumulative nature of scientific knowledge.
What happens when new information is dicoverd about a theory?
The theory is evaluated in the context of the new information. The information may support the theory, it may require a tweak to the theory to accommodate the new information or it may require a major re-think of the theory.
How are scientific theories related to observations and evidence?
Scientist use scientific methods to test the new theory. They also examine all the evidence to see if it supports the new theory. Scientist accept a new theory when many test and pieces of evidence support it.
Can scientific theories change?
Yes, they can, if new evidence is discovered to support a change in the theory. Physical theories are not provable in the sense of mathematical theorems. They depend on evidence, and they can be disproved if enough contrary evidence comes up.
Under what conditions can a scientific model or theory change?
A scientific model can change if new evidence is found. If the new evidence that has been found contradicts the model or theory then a scientific model or theory can change.
What is a scientific theory that has been changed due to new evidence?
When new evidence is found, the theory is tested against the new evidence, if the theory and new evidence are compatible then the theory is confirmed, if the new evidence and the theory are not compatible, then this indicates the theory is wrong and the theory must be abandoned or modified. Sometimes a theory will predict that new things (evidence) will be discovered. In such cases when these things are discovered AS PREDICTED, the theory becomes stronger. For instance some of the outer planets were predicted (using orbital and gravitational theory and observation on the orbits of known planets) and they were later discovered close to where they were predicted to be.
