Experts Have Created The First 3-D Map Of The Universe


Scientists have created the first 3-D map of the Universe

Scientists have created the first 3-D map of the Universe. A team of hundreds of scientists worked closely together to map a quarter of the known Universe.  The model was created through painstaking measures that reached into the earlier “time zones” of the galaxy. The map comprises 650 million cubic light years of space, which includes 1.2 million galaxies.

It was crafted to measure dark energy. Scientists could only recently prove that the expansion of the universe is accelerated. Dark energy is seen as the “anti-gravitational” force responsible for it. These new developments in understanding the Universe prove Einstein was right.

This huge project concluded that the laws of relativity and gravity happen on a universal level. It further proved that dark energy is the factor for the accelerated expansion of the universe. The research showed that this energy follows Albert Einstein suggestion of Lambda, a constant that acts as a repellent countering attraction between matter.

The map is based on a Spectroscopic Survey (BOSS), a project that measures the lasting impact of acoustic waves which were present in the early version of the universe. The map not only shows the structure of the universe but also has implications for understanding how the expansion works and for validating astronomical theories.

The scientists took into consideration the movements of galaxies which are far away from us, with a model called “the redshift space distortion.”

As experts took these variables into consideration and compared their data, they measured distances, the dark matter quantity and the dark energy that fills the universe. Dark matter and dark energy still hold a lot of secrets to scientists and could help us understand how the universe works and how it will continue its expansion.

Ordinary matter, electrons, neutrons, and protons make up only around 5 percent of the universe. What’s left is part dark matter, part dark energy. This work represents a step forward for astronomers.  For the first time, scientists were able to combine precise measurements with the extensive observation of cosmic microwaves, to produce a platform for the standard cosmological model.

In the coming decade, the program is going to be extended with even larger spectroscopic surveys.
