Did we just discover what dark matter is made of? Maybe sterile neutrinos are the solution!

DNews reports that sterile neutrinos could be the candidates for dark matter. Those are neutrinos that have masses between the electron neutrino (0.3 eV) and muon neutrino (0.115 MeV). In fact, it seems that the sterile neutrino might have a mass of just about 3.55 keV as it gives off X rays in that band […]

What is dark matter?

Psysics Girl explains us what dark matter is and how they could know suck a thing really exists. Dark matter seems to be composed on wimp – weakly interacting massive particles and it does not interact with electromagnetic radiation. You only know it is there because it causes a gravitational pull on things. The scientists […]

Dark Matter is all around us

Yes. We are used to thinking that dark matter is somewhere far away and it just plays with the astronomers, but according to the theory dark matter is all around us. The minor issue is: how can we detect something that influences gravity, but cannot be detected with the tools we use. Mostly we analyse […]

Dark matter rap – dance like it’s Universe’s deal

Dark matter is supposed to be the answer to about 80% of the mass of the Universe. The small issue is that is has gravity, but it does not reach with electromagnetic radiation and, thus, you cannot see it with naked eye or using radioastronomy tools. Enjoy the dark matter rap. Someday, in the future, […]

Black Holes and Dark Matter explained [video]

Today I had some free time so I roamed through some YouTube videos and stopped at these. They explain what black holes are and why dark matter is such an important concept for astrophysicists. Black holes are cosmic objects so dense that not even light can escape from them if it gets too close. They […]
