the universe

New research has improved the accuracy of the parameters that control the expansion of the universe. More precise parameters will help astronomers determine how the universe grew to its current state, and how it will evolve in the future.
A special article in honor of Hebrew new year summarizing the creation of the world through the lens of science
The "Dark Universe" Euclid space telescope is launched on a mission to uncover the deepest mysteries of the cosmos
A team of researchers confirmed Hawking's prediction of evaporating black holes, but extended its application to all large objects in the universe
A groundbreaking new map of dark matter has been created using data from the Dark Energy Survey (DES), in an international collaboration of astronomers and physicists. The map shows the distribution of dark matter in the southern sky region, and is the most accurate and detailed map of its kind ever created
The new hypothetical particles may be able to explain the observations made by the Cosmic Source Spectrograph on the Hubble Space Telescope
Researchers who have examined whether Einstein's theory of gravity works on the largest possible scale claim that there are deviations that need to be checked and corrected similar to those at small distances that can be answered using quantum theory
It's been more than 50 years since astronomers first proposed "dark matter," which is thought to be the most common form of matter in the universe. Even so, we have no idea what dark matter is. No one has seen dark matter directly or produced it in a lab. But are there competing theories that explain the same data better?
According to new research, an invisible "mirror universe" of particles that interacts with our world only through gravity could be the key to solving a major mystery in cosmology today - the Hubble constant problem
Following the new Marvel movie "Doctor Strange in the Dimensions of Madness" which takes place in the Multiverse, I decided to break down in a short article the meaning of parallel universes and the reasons to believe in their existence. In my opinion, science surpasses any imagination, including Marvel's imagination.
Researchers from Prague published in the prestigious journal Physical Review Letters an alternative model for dark matter based on MOND that succeeds in predicting the existence of the cosmic background radiation. This is a significant achievement that the MOND model has so far failed to explain, and for this it has received most of the criticism against it. the price? Two new fields in Teva. The authors of the article hope in the future to prove its existence with the help of the model's unique fingerprints on the gravitational waves.
The scientists thus discovered some of the missing baryons of the universe, and confirmed that 80-90% of the normal matter is found outside galaxies, an observation that will help to expand the models of galaxy development.
Prof. Yaholum explained why the rotation speed of the matter in the galaxies does not decrease as you move away from the center of the galaxy starting from the outskirts, but remains the same or even increases * It is estimated that dark matter is involved in the process. According to Prof. Yahlom and his colleagues, these phenomena can be explained according to a theory known as the theory of delay - the amount of time it takes for the effect of an event in the center of the galaxy to spread to its edges.
Traces of the radioactive plutonium were found in a deep-sea mineral in the Pacific Ocean, which is a millions-year-old archive of material from the Earth but also of cosmic dust that settles on it
Researchers around the world are looking for an explanation for the mystery of dark matter and the problem of hierarchy. The two problems seem completely different, but according to researchers from Johns Gutenberg University in Germany, both can be solved with the help of a compact fifth dimension. The estimated model does not contradict the experimental data discovered in current accelerators and predicts a new particle with a mass of 30TeV that may be discovered in future accelerators
