After years of experimentation and testing, it is possible to prove that a hypothesis is true, at which point it becomes absolute truth

Yes that is "True".

Hypothesis is a prediction that can be tried or it is an informed guess. In this, researchers work out a prediction about what they to think will happen or is going on in their investigation. They attempt to answer their inquiry or issue.  

Absolute truth is something that is valid consistently and in all spots. It is something that is in every case genuine regardless of what the conditions. It cannot be changed. For instance, there are no round squares.
