Truth

What is the truth?
Is it the same as fact?

Science has come up with many facts over the years, but these seem to have changed as time has moved on. It also gets confused with theory. Science once theorized that we evolved from apes and this some how entered the general public's mind as fact. Science however no longer believes this to be true.
Here is another case in point. Science once stated that the speed of light was a constant, this theory also has been ditched as they now believe that the speed of light decreases as it passes a strong magnetic field.
Truth, if it is anything, surely is never changing and never contradicts itself, something that science does on a near monthly basis. By this calculation alone we must come to the conclusion that science is not truth. So what is?
The statement "What is true for you" must also be reasoned as being unacceptable as that implies that truth varies depending on an individuals beliefs. What is actually being spoken about here is opinion based on circumstances and (genetics, if you adhere to such beliefs).
So truth can not be refuted, otherwise it is not the truth, merely an opinion or theory or (fact, also known as science)

Truth can always be challenged but will always stand any kind of test and it is what I try to live my life by: The Truth
