A new large-scale study of space reveals new details about dark energy. It turned out that this energy not only maintains its specific density over time, but can also evolve with the cosmos.<\/p>\n\n\n\n
Despite the fact that dark energy is an integral part of the Universe and accelerates its expansion, it is still poorly understood. To investigate this phenomenon, the most extensive three-dimensional map of the Universe was created using the Dark Energy Spectroscopic Instrument DESI.<\/p>\n\n\n\n
The study analyzed the data from the first year of observations, mapping the locations of 6.4 million galaxies and quasars, the super-bright cores of active galaxies. This map allowed scientists to estimate the rate of expansion of the Universe.<\/p>\n\n\n\n
Analyze sound waves that created patterns of dark matter density in the early Universe. The density of matter was preserved when galaxies were formed, but it was different in each galaxy, which is why galaxies are located at a certain distance from each other.<\/p>\n\n\n\n
This distance acts like a ruler that stretches as the Universe expands. Studying this ruler in different epochs can show how the boundaries of the Universe expanded at different times of its existence. Scientists have divided the Universe into seven epochs, stretching back 11 billion years, and studied their evolution.<\/p>\n\n\n\n
After analyzing all this combined data, they confirmed the theory that dark energy evolves over time and is not a stable indicator. But these are only the first results. The scientists plan to collect data over the next five years, cataloging 3 million quasars and 37 million galaxies.<\/p>\n","protected":false},"excerpt":{"rendered":"
