Renegade liquid

Renegade liquid –

negative mass pushing back

breaking second law.

 

One of the fundamental aspects of Newton’s second law states is that when an object has a force applied to it, it moves in the same direction as the net force. Khamehchi et al (2017) created a liquid of negative effective mass (a Bose-Einstein condensate) that breaks this principle: when it is pushed it accelerates towards the pusher.
