    Dark energy Testing
AI Thread Summary
Astrophysicists have created a new method to measure the cosmological constant by analyzing the dynamics of the Local Group. This approach currently provides constraints on dark energy that are five times less effective than existing methods. However, researchers believe that improvements will soon enhance its effectiveness to match current measurements. The study highlights the potential of using local cosmic structures to gain insights into dark energy. This advancement could significantly contribute to our understanding of the universe's expansion.

Unfortunately, it is so far five times less constraining than other measures, but promises to improve to be comparable with existing measures soon.
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
