I Does the external field effect prove MOND over dark matter?

AI Thread Summary
The paper "Testing the Strong Equivalence Principle: Detection of the External Field Effect in Rotationally Supported Galaxies" presents a 4 sigma detection suggesting that dark matter models fail to account for certain observations. The study focuses on 153 galaxies, raising questions about the implications for Modified Newtonian Dynamics (MOND) if the findings are validated. The discussion centers on whether these results could favor MOND over dark matter theories. The potential significance of the external field effect in understanding galaxy dynamics is emphasized. If confirmed, these results could challenge existing dark matter paradigms.

Testing the Strong Equivalence Principle: Detection of the External Field Effect in Rotationally Supported Galaxies

Kyu-Hyun Chae1

, Federico Lelli2, Harry Desmond3, Stacy S. McGaugh4, Pengfei Li4, and James M. Schombert5 Published 2020 November 20 claims a 4 sigma detection, and that dark matter cannot reproduce this.

i understand this is only 153 galaxies and not 153 million galaxies, but if the results hold up, does this mean MOND?

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. In case of failure to detect...

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...

Thread 'Could fast radio bursts be alien radar signals?'

Both have short pulses of emission and a wide spectral bandwidth, covering a wide variety of frequencies: "Fast Radio Bursts (FRBs) are detected over a wide range of radio frequencies, including frequencies around 1400 MHz, but have also been detected at lower frequencies, particularly in the 400–800 MHz range. Russian astronomers recently detected a powerful burst at 111 MHz, expanding our understanding of the FRB range. Frequency Ranges: 1400 MHz: Many of the known FRBs have been detected...
