Hi everyone, I thought you would be interested in the latest discovery about the composition of the universe. In short, the best physical models of the Universe can explain only about 5% of its total mass. The remaining 95% consists of unknown matters / effects called Dark Matter and Dark Energy. These substances are called 'dark' because of their weak interactions with electromagnetic forces (i.e. light), and we can detect them only by their gravitational influence. We do not know yet what these effects are, and there are many theories aiming to explain it. In December 2018, Dr. Jamie Farnes published an article entitled 'A unifying theory of dark energy and dark matter: Negative masses and matter creation within a modified CDM framework', in which he proposes that dark matter should be negative mass matter: https://www.aanda.org/component/article?access=doi&doi=10.1051/0004-6361/201832898 Okay, what's so great about this theory? It can be said that this is another mathematical hocus-pocus, which is nothing more than a paper exercise. Well, Dr. Jamie Farnes also attached a pretty convincing simulation in which he modeled the interaction between both types of matter (with positive and negative masses): https://www.youtube.com/watch?v=AsdMhdxAaJ8 The resulting structure is very similar to what we call the 'Cosmic Web', which is a consequence of the Big Bang and inflation that created our universe: https://en.wikipedia.org/wiki/Galaxy_filament Is Dr. Jamie Farnes' theory right and the Dark Matter is a negative mass matter? I'm sure I will be following this subject. Take care, Les
