Supernatural and Atheism

[Anomalocaris]

Do you say those things are beyond doubt as well?  What if, for example, we find that dark matter is attributed to a modification of General Relativity that kicks in when space-time is sufficiently flat, such as in intergalactic space?  If GR is beyond doubt then such modifications would never be entertained.

In my opinion, some things are facts, and therefore, are beyond any (reasonable) doubt.  As Isaac Asimov stated,

John, when people thought the earth was flat, they were wrong. When people thought the earth was spherical, they were wrong. But if you think that thinking the earth is spherical is just as wrong as thinking the earth is flat, then your view is wronger than both of them put together."

Isaac Asimov - The Skeptical Inquirer, Vol. 14 No. 1, Fall 1989

Scientific theory is only of value if it accurately predicts something otherwise unknown.     To say the theory is fact merely because it seems to have worked as well as can be expected upon what is already known doesn’t exactly guaranty  its on-going value.     Whether the theory would work as well in a new place where one previously have not looked can and should always be doubted and then tested.      To assert that just because a theory worked in all cases hitherto tested therefore it is an all encompassing fact everywhere else as well is frequently the beginning of folly.
