I work for an aerospace R&D company. One of our projects was functioning as a subcontractor for the recent Stardust mission. You can read about it here:
As a result of the data collected from the Stardust mission, previous assumptions about the formation of the solar system are being overturned.
Today, the Stardust program manager copied all the Stardust research contributors with a congratulatory note that included the following comment:
A week and a half ago the science team met — 120 of the more than 200 scientists around the world working on the particles brought back, and they are already rewriting the texts on how the solar system formed, with the discovery of refractory minerals that require very high temperatures to form and were somehow ejected from very near the sun to the outer reaches of the solar system in the Kuiper belt way beyond the orbit of Pluto.
If, in a hard science like this, previous assumptions can be reexamined and even overturned, how about the assumptions of a soft, philosophical “science” like Darwinism?
