100-year-old physics problem has been solved
<i>"For more than 100 hundred years, these systems were held back by a limitation that was considered to be fundamental ... But that limitation is now a thing of the past."</i><p>We should bear breakthroughs like this in mind every time someone appeals to fundamental limitations of physics (or any other field).<p>So many times I hear people object that something can't be done because of some fundamental limit.  But research like this proves that limits that are considered fundamental sometimes aren't, and we can't know ahead of time which of these limits really are fundamental and which only appear so.
