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.
