To account for this observation, physicists came up with a new type of energy – called dark energy – which supposedly makes up more than 75% of the universe, and also has negative pressure. In a new paper, mathematicians claim that dark energy isn’t needed to explain that accelerating expansion, and physicists have been barking up the wrong tree for decades. Let’s take a look.
