neutrons and electrons. Scientists only speculate what dark matter is made of. It could be composed of baryons but it could also be non-baryonic, which means consisting of different types of particles.
What is Dark Matter? First, understand that the term “dark” simply means it’s not visible like the planets, stars, comets, asteroids, gas clouds, and other objects that we see. Only 5% of the universe is made of visible matter. Dark matter is not visible to us because it emits no...
This still doesn't guarantee dark matter is made up of axions, though; it just means axions might be an essential piece of the puzzle. In Germany, scientists are trying to observe dark matter in a bold new way: by creating it. ALPS II, an experiment at the Deutsches Elektronen-...

Scientists have several candidates for the types of particles that make up dark matter. One possibility is that dark matter is made of WIMPs (weakly interacting massive particles) that would have 1 to 1,000 times more mass than a proton. Another candidate is the axion, a particle ten-trillio...
By adjusting the hormone levels, the researchers can tune the physical and mechanical qualities of the cells. Next, the researchers use a 3D printer to shape the cell-based material, and let the shaped material grow in the dark for three months....
