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.

    How do you know the bird in the tree over there is real?

    Well you can see it, photons have been emitted from the bird, which are captured by your eyes.

    This is fundamentally identical to how we detect objects in deep space, we capture the photons, the neutrinos, the gamma rays, gravitational waves, whatever energetic emission is coming from them, and that’s how we know they exist.
