If your data does not support your hypothesis, it means that there is not enough evidence to conclude that your hypothesis is true. In such cases, you may need to reconsider your hypothesis, collect additional data, or revise your experimental approach. It is important to acknowledge and learn from results that do not support your initial hypothesis in order to refine your research and understanding.

In experimental design, the null hypothesis serves as a foundational statement that posits no effect or no difference between groups or conditions. It provides a baseline against which researchers can compare their experimental results. By testing the null hypothesis, researchers can determine whether observed effects are statistically significant or could have occurred by chance. If the null hypothesis is rejected, it suggests that there is enough evidence to support an alternative hypothesis.
It will become an Exploit.
The hypothesis can never really be proven correct; that's why scientists always say that they are 99.9% sure about things. If you drop a pencil, it will most likely always fall, but there is the slight chance that someday, it won't fall. Things in science always change.
Two reasons why data might not support a hypothesis are that the experiment had a flaw or was not repeated enough times. This happens a lot.

Yes. The next step is to try and gather enough evidence to support the hypothesis.
You are supposed to assume/expect that nothing happens, or the norm happens. E.g. if you are testing if plants grow more in light, you assume they dont, then see if that expectation is consistent with the result.
Simply put, because there is not enough evidence to support it. "Rejected by scientists" should not be taken to always mean "scientist believe it is impossible" - rather, consistent evidence that support the hypothesis has not been produced.
A statement of no difference in experimental treatment refers to a hypothesis asserting that there is no significant effect or change resulting from the treatment being tested compared to a control group. This is often formulated as the null hypothesis (H0), which posits that any observed differences in outcomes are due to random variation rather than the treatment itself. Researchers use this statement to guide statistical testing and to determine if there is enough evidence to reject the null hypothesis in favor of an alternative hypothesis that suggests a significant effect.
