Nothing in the universe violates thermodynamics.
That depends. Your statement would be correct if you had added, "...for longer than a second or two." For a long time there have been observations of microscopic particles that did not conform to the laws of thermodynamics. In order to reconcile the behaviour of these particles with thermo, "fluctuation theorem" was developed. Back in 2002 predictions of "fluctuation theorem" were successfully tested. Random and spontaneous decreases in entropy were observed. But the time periods involved were short, no more that 2 seconds, and the decrease was paid back with a corresponding increase as equilibrium was restored. But still, even though temporary, it is a violation of thermodynamics. However, there doesn't seem to be any way to take advantage of this "violation" and there doesn't appear to be any prospects of doing so in the future.
