Don't assume that what we currently think is out there is the full story. Go after the dark matter, in whatever field you choose to explore.

Additional Information: This quote is from biologist and explorer Nathan Wolfe's 2012 TED Talk about what he thinks is left for the world of science to explore. In this talk Wolfe discusses "biological dark matter" -- biological information, including forms of life, that can't be classified or understood based on the current scientific paradigm. In this context, Wolfe's quote means that people should remain curious and never assume that the current body of knowledge represents the full truth, whether in biology or in another field. Wolfe elaborates on this quote by saying, "There are unknowns all around us, and they are just waiting to be discovered." Watch the full TED Talk here: Nathan Wolfe - What's Left to Explore?
