There are actually ways in which science can come up with the wrong answer - for example if we lived much later, the universe would be expanding so rapidly that we could not see the stars around us - the night sky would be dark. We would wrongly conclude that nothing is out there.
Sadly, what people call science these days has nothing to do with the scientific method, it's just a bunch of idiots doing correlation and thinking it's causation.
If the sky is dark, it is because there is nothing out there. That's what "nothing" means: that which provides no evidence or experience from which to demonstrate its existence.
