It's an undecidable questions (a question with no answer, and if an answer exists it could be impossible to prove). Currently there is no way to view the universe without bias, for humans this manifests itself in our limited spectral range, our flawed senses and our over 200+ cognitive biases that influence the way we think every day. Whether or not these biases are truths or lies can't be known, all I know is that currently no one can view anything without a huge amount of bias.
Are we, as humans, getting to the limit of what we can understand about the universe?
