This is something that has been bothering me for a while as I’m diving through space articles, documentaries etc. All seem to take our observations for granted, which are based on the data of the entire observable universe (light, waves, radiation…) we receive at our, in comparison, tiny speck. How do we know we are interpreting all this correctly with just the research we’ve done in our own solar system and we’re not completely wrong about everything outside of it?

This never seems to be addressed so maybe I’m having a fundamental flaw in my thought process.
