Physicists create mind-bending ‘negative mass fluid’

‘US scientists have managed to surprise science geeks across the globe, creating a unique fluid with negative mass – but that actually stands for an object moving forward when pushed back.
The creation began inside a lab at Washington State University (WSU), when physicists cooled rubidium atoms to just slightly above absolute zero. This created what is known as a Bose-Einstein condensate.
When particles are in this state, they move extremely slowly and behave like waves. They synchronize and move in unison as ‘superfluid,’ which flows without losing energy, according to a WSU press release.’
