Although science and technology have advanced tremendously, dark matter is still supposed to be one of the most critical things in the realm of astronomy and cosmology. But what the hell is dark matter? Well, it is a type of matter hypothesized to account for a large part of the total mass in the universe. The interesting thing is dark matter is invisible and therefore it can’t be seen directly even with the world’s most powerful telescope. But the invisibility of dark matter couldn’t stop NASA from creating a sharp 3D map of this mysterious substance.
Dark matter neither absorbs light or other electromagnetic radiation nor emits or reflects. It is not even a Black Hole. Dark matter is invisible but it do exist. It’s something like believing that there is God, though we can’t see him. It is assumed that 84% of the matter in the universe and 23% of the mass-energy are constituted with dark matter.
However, using some data collected from the NASA/ESA Hubble Space Telescope, for the first time ever, astronomers and scientists have created a three-dimensional (3D) map of how the dark matter is distributed across the Universe. This new 3D map apparently looks like a map of a city.
NASA said, “Mapping dark matter’s distribution in space and time is fundamental to understanding how galaxies grew and clustered over billions of years. The map stretches halfway back in time to the beginning of the universe, and reveals a network of dark matter filaments, collapsing under the relentless pull of gravity and growing clumpier over time.”
If dark matter’s distribution in space and time becomes clear to scientists, it would be easy for them to understand how galaxies grew and clustered over billions of years.
