These properties make them the perfect hiding place for the missing matter.
AMS-02 is a particle detector based on the International Space Station (ISS) and its mission is to search for antimatter, dark matter, and missing matter in space.
That missing matter has been converted to energy and you can calculate how much using Einstein's equation.
There is a lot of controversy about what dark matter is, but couldn't some of the missing matter be contained in black holes?
Now we are certain in two things: some fraction of the missing matter is in the filaments, and taking risks can be very rewarding.
This missing matter — which is different from dark matter -- is composed of baryons, the particles, such as protons and neutrons, that are found on the Earth, in stars, gas, galaxies, and so on.
There are also so many neutrinos that even if they only had a mass one five thousandth that of the electron, the mass of all the neutrinos in the universe could make up for the missing matter.
Astronomical measurements dating back to the 1930s have shown that the visible elements of the universe like galaxies are being buffeted gravitationally by invisible clouds of Something Else, once pegged "missing matter".
The presence of this missing matter in the centres of galaxies and clusters of galaxies has also been inferred from the motion and heat of gas that gives rise to observed X-rays.
The stars and galaxies, were moving as if immersed in the gravity of giant invisible clouds of so-called dark matter -- "missing matter" the Swiss astronomer Dr. Fritz Zwicky labeled it in the 1930's.
