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.
Clusters of satellites, such as the BlueWalker 3 prototype, are causing concern among astronomers due to possible interference with night sky observations and radio astronomy. Balancing the global needs for communication and maintaining astronomical research is critical. Credit: AST SpaceMobile

The BlueWalker 3 satellite whose antenna area is 64 square meters has become one of the brightest objects in the night sky, the fear is that when there are a hundred satellites in this constellation and hundreds in other constellations it will be impossible to observe the sky in the optical field and there will also be interference to the radio field

Einstein is considered the greatest theoretician, along with Isaac Newton, the father of classical mechanics. His name became synonymous with genius. He gained worldwide fame in the first quarter of the 20th century thanks to the theory of relativity he developed

First simulation of a wormhole on a quantum computer

A team of researchers from Harvard University, MIT and Calcutta in collaboration with Google successfully simulated a traversable wormhole with the help of a quantum computer. The experiment performed on Google's quantum processor demonstrated the passage of information in the interlaced system. According to the principle of holography, the physics demonstrated in the experiment is the same as that of particles passing through wormholes. Although it was conducted on only nine qubits, the experiment is of great importance because it illustrates for the first time the possibility of testing quantum gravity with the help of entangled systems.
An image of about ten thousand galaxies is called: "Hubble's vast deep field". The image includes galaxies of a variety of ages, sizes, shapes and colors. About 800 of the small red galaxies may be the most distant galaxies to be seen. They were created when the universe was 13 million years old. The nearest galaxies - the luminosities with a distinct spiral or ellipse shape - are about a billion light-years away, when the universe was 800 billion years old. The image required 400 exposures taken during Hubble's 11.3 orbits around the Earth. The total exposure time was 24 days, between September 2003, 16 and January 2004, XNUMX. Photo: NASA, ESA, and S.

Scientists from the SLAC accelerator and Stanford University combined experimental data and theory to understand how the universe formed and what the future holds. Stringy clumps of dark matter (black regions) serve as scaffolds for the construction of cosmic structures made of normal matter (bright regions), which include stars, galaxies, and galaxy clusters.
