Has there ever been a scientific fact that stayed a fact, not been proven wrong or explained differently for over 30 years?
Question Date: 2018-04-29
Answer 1:

Of course! Lots and lots of things in science are considered facts - until they can be proven wrong. For one example, for a long time humans thought all the planets and the sun rotated around the earth. This was believed for thousands of years, until a scientist named Copernicus proved that the sun is actually the center of our galaxy (which is a part of the universe). Copernicus came up with this idea in 1543, and has been proven to be true by others over and over again. This would mean that this fact has been known for close to 500 years!

This is just one example though. In science, everything goes through what is known as the "peer review", which is a fancy way of saying that lots of other scientists need to look at someones idea and decide if it makes sense. Something might be considered true for 5 years, but then someone proves it wrong.

That is what makes science important - Facts can only be as good as the science that studies them. We don't know everything already - if we did, scientists wouldn't need to exist.

If someone can prove why something is different, that is when a "fact" changes.
