Answer:
Observations; control. 
Explanation:
A hypothesis is considered to be tentative or an educated guess and can be defined as a testable explanation for an  observation or a scientific problem. An example of a hypothesis is saying, Corona virus is caused by the introduction of the "5G" technology. 
On the other hand, a control experiment  can be defined as an experiment in which a condition assumed to be a probable cause of the effect is being compared to the same  situation by the scientist without involving or using the suspected condition.
Hence, science rejects any hypothesis not supported by observations and the results of control experiments.
<em>This ultimately implies that, for any hypothesis to be acceptable in science, it must be supported by observations and the results of control experiments; this give rise to factual informations, theories and by extension solutions to problems.</em>
 
        
             
        
        
        
The scientific method is a process of steps in order to get a conclusion. First, a scientist will observe something. It could be really anything. Then he/she will ask themselves a question. Like how does it do that? Or why does it do that?
Then they will form a hypothesis. This is where you will ask yourself what will be the outcome of the experiment.
Next you actually perform the experiment. If the experiment comes out as your hypothesis predicted, then you accept your hypothesis.
If not, you reject your hypothesis.
Of course, in science you just don't do one experiment. You do it multiple times and even with different circumstances.
        
             
        
        
        
They will burn into a white Dwarf and then eventually into a black dwarf
