A small part of the universe we observe has the highest-temperature gas or dust around it, but it’s been a mystery why. The Universe is a huge place, and it’s important to understand its formation processes – and their interactions – in order to understand the cosmos as a whole. And we know that the gas and dust you see around us is not a uniform bubble, but has the properties of a massive cloud of gas with much energy trapped in space.

It turned out that the Universe contains some of the most powerful particles we ever discovered. All the neutrinos we’ve ever measured are, for the most part, incredibly small – one femtometer is one billion billion billion billion trillion trillion (one billion billion trillion billion billion billion billion billion billion trillion). Neutrinos are so incredibly simple that we’re not sure what they’re really for – perhaps they’re for measuring the speed and directions of electric currents. However, it’s clear that neutrinos play important roles in other fields. It’s an important topic that has attracted tremendous interest to physicists, but it hasn’t been well addressed scientifically.

In a special report to accompany the publication of the findings of a new team of researchers, scientists of the Max Planck Institute for Chemistry in Germany describe a new approach for studying matter at extremely high energies, in a process known as “vacuum inflation”. This means that they think we may be able to explain what makes the Universe behave such that there are so many very tiny, very far away particles flying around, and that everything seems to be going
