Which scientific ideas should die?

Science is always investigating new ideas and disproving old ones.  If we are to continue to move forward, which of the current scientific ideas about our world are obsolete and should be discarded?

How about the universe as we know it?

That’s the premise of a Science Friday program, which was broadcast on National Public Radio on February 27, 2015.  I don’t profess to completely understand the logic, but it’s an interesting thought.
