Two researchers at the Czech Academy of Sciences are rocking the astrophysical community with a new modified Newtonian dynamics (MOND) theory that abandons the concept of dark matter and instead supports a theory that suggests that there is still some sort of thing. Undiscovered gravity responsible for the attributes found in the Cosmic Microwave Background (CMB). Constantinos Skordis and Tom Zlosnik have published a paper explaining their ideas Physical review letter..
For several years, much of the astrophysics community has used the concept of dark matter to explain phenomena that traditional methods could not explain. For example, measuring the gravitational wave velocity seen with a gravitational lens or CMB. Others were less willing to accept dark matter due to lack of physical evidence of the existence of dark matter. Instead, some suggest that another kind of gravity may be working that may explain such observations. However, these MOND theories are less important as they cannot explain the features found in CMB. The situation seems to have changed as Skordis and Zlosnik claim to have taken such data into account and built a MOND model that takes gravitational lenses into account.
The new model begins with the use of the original MOND idea of two types of fields that work together as a type of gravity. One is scalar and the other is vector based.Next, the researchers added a parameter that suggests a gravity-corrected field generated by. Early universe— Imitation of darkness Matter.. These fields further suggest that they have evolved over time to the type of force described in the original MOND model.
Skordis and Zlosnik suggest that their model can be used to explain both. Gravitational lens And CMB data.Next, they plan to find out if it can explain the discrepancy in measuring the abundance of lithium in the universe and the rate of expansion of the universe-something. Dark matter The theory has failed. They also point out that their ideas do not have ghost instability.
