Physicists observe ‘negative mass’

Neat, and weird…

Physicists have created a fluid with “negative mass”, which accelerates towards you when pushed.

In the everyday world, when an object is pushed, it accelerates in the same direction as the force applied to it; this relationship is described by Isaac Newton’s Second Law of Motion.

But in theory, matter can have negative mass in the same sense that an electric charge can be positive or negative.

Oh; I was hoping ‘negative mass’ could be used for weight loss… 😉
