Today we learn that a theory that proved Newton's laws of motion were wrong* is possibly in itself wrong because neutrinos may in fact have travelled faster than the speed of light, fired from CERN to Italy. (The BBC has this)
This is not actually either a surprise or unusual. Real scientists (Not Richard Dawkins) are always finding out that what they believed last week was not quite right and so knowledge progresses. There can be no truths in science, because if there were it would become a religion and so not gain further knowledge. That said parts of the science community do turn religious in their dogma holding things up for a while.
Religion on the other hand is truth. This is not because it can be proven in a scientific sense but because it tells us something beyond fact about ourselves, our relationships with others, the world and our responsibility over it. Religions vary, but most contain some parts which many people would call a truth.
On the other hand with science you must always be testing and breaking the current position or else it does not move forward.
*I am being a bit hard on Newton's laws of motion, they work quite well at the level of practical human experience.
