LIVE Techno – In space, amazing discoveries continue to be made. These distant objects continually reveal that our solar system is much larger than initially thought and previous observations have been made that there are parts of the sun that are damaged.
For example, recently, there is evidence that suggests the existence of an undiscovered ninth planet located at the edge of our solar system and could prove that our understanding of gravity is wrong.
Planet-planets of Tata Surya.
This discovery was made by two scientists who studied the influence of the Milky Way galaxy on objects at the outer edge of the solar system.
Galaxies are able to rotate very quickly without any of their contents escaping or being thrown around, and most experts believe that the presence of dark matter may explain why.
Dark matter is invisible and does not emit or reflect light, and it is hypothesized that galaxies are surrounded by rings of dark matter that bind them in their own gravitational pull and stop them emitting matter.
However, now the Modified Newtonian Dynamics (MOND) theory of gravity may suggest that dark matter is not the reason why galaxies remain intact despite their very high rotation speeds.
In contrast, some people believe that below the rotational speeds that galaxies experience, a new type of gravitational behavior occurs.
Case Western Reverse scientist Harsh Mathur explains: “MOND is great at explaining galaxy-scale observations, but I didn’t expect it to have such a noticeable effect on the outer solar system.”
MOND eliminates the need for dark matter, and instead states that Isaac Newton’s famous law of gravity is true, but only up to a point.
In contrast, MOND states that, under high rotational speeds, a different kind of gravitational behavior will take over—behavior that also applies to rotating galaxies.
Experts believe this may be caused by the presence of an undiscovered ninth planet, because this is a phenomenon that occurred previously with the discovery of new planets due to their gravitational pull attracting other solar system objects.
Katherine Brown, professor of physics at Hamilton College, said: “We wanted to see whether the data supporting the Planet Nine hypothesis would effectively rule out MOND.”
Planet 9 plays a role because objects in the Kuiper belt (the disk surrounding the outer edge of our solar system) are observed to be clustered together and exhibit orbital anomalies that do not occur for other objects in the belt.
Their study reveals that the hypothesis may be correct and could point to the existence of Planet 9, but they argue that their data set is so small that no definitive conclusions can be made yet.
Brown explained: “Whatever the outcome, this research highlights the potential of the outer solar system to serve as a laboratory for testing gravity and studying fundamental problems of physics,” concluded Brown. The duo’s work was published on September 22 in The Astronomical Journal.
