What is the universe made of? Atoms only make up a small proportion of what we think is out there, so cosmologists are trying to explain what the ‘missing’ 95% might be, and find ways to investigate its behaviour. Dr Jo Dunkley brings us up to speed on the latest research.
Suitable for 13+
More information
One of the outstanding problems in cosmology is to understand the ‘missing’ 95% of the universe. The familiar atoms we are all made of only make up a small fraction of what we think is out there. We think that about a quarter of the universe is made of Dark Matter, most likely an undiscovered type of particle that we cannot see, but feels the effect of gravity. The other 70% is what we call Dark Energy, thought to be a form of energy that has the strange effect of making the expansion of the universe accelerate. Finding out what these are, and coming up with ways to investigate their behaviour, is a central part of current research in cosmology. It brings together research in astrophysics and particle physics, and combines theoretical studies with large international experiments.
