Astrophysicists test a new piece of the sky to probe dark matter and dark energy

In the leading model of cosmology, most of the universe is invisible: a combined 95% is made of dark matter and dark energy. Exactly what these dark components are remains a mystery, but they have a tremendous impact on our universe, with dark matter exerting a gravitational pull and dark energy driving the universe's accelerating expansion.

A massive new project maps dark matter using 100 million galaxies

Most of the universe cannot be seen with any telescope, and that is not because scientists lack powerful tools. It is because the cosmos is ruled by substances that give off no light at all. Dark matter and dark energy make up about 95 percent of everything that exists, shaping galaxies, stretching space, and guiding cosmic history. Now, a massive new study gives you one of the clearest views yet of how that invisible universe is arranged. Astro…

Are We About To See Dark Matter For The First Time Or Is It All An Illusion?

The reason we have given dark matter its name is simple. We can’t see it with our eyes or make it visible using imaging technology. Does dark matter react to parts of the light spectrum? Can we see evidence of it through electromagnetism? Some question its existence at all. The consensus among physicists, astronomers and cosmologists today, however, is that dark matter very much is real and that it accounts for approximately 85% of the Universe’…
