Currently, Einstein’s general relativity theory that explains gravity is being intensely scrutinized and questioned. The formation of galaxies and black holes in the Universe can be possibly explained through this theory. After the implementation of the latest supercomputer simulations in the theory, it was termed as “Chameleon Theory.” This theory could help explain the formation of galaxies and other entities in the Universe so as to make it simpler for scientists to understand the dark matter and dark energy. According to scientists from the University of Durham, this new theory regarding gravity can explain the fluctuations and changes in the effects of gravity based on the environment.
In the general relativity theory, the gravitational force is measured as a constant. Even though it has been experimentally validated, the Chameleon Theory cannot be ruled out. Chameleon Theory can also simulate the exact same Universe as ours with the galaxies and black holes. But the only difference is that the dark energy is treated as a constant mysterious force that is tearing apart the Universe by general relativity, whereas Chameleon theory treats force as fluctuating variable. By altering the variables of gravity and dark energy in the latest simulations, the quantity of gases consumed or burned down by supermassive black holes is affected and this, in turn, is known to determine the number of stars formed in a galaxy.
Chameleon Theory asks for modification in the laws of gravity that can help understand the effect of changes in gravity on galaxy formation. The change in gravity would possibly not affect the formation of disc galaxies having spiral arms. The Durham scientists just want to figure out the dark energy’s behavior through this study rather than proving the theory of general relativity wrong. Parallelly, the Hubble Space Telescope has recently spotted a rare supermassive black hole that should not exist. The galaxy NGC 3147 has the black hole centrally located with an unusual thin disc encircling it. As the galaxy is starving of the gravitationally pulled objects, the presence of the disc around the black hole is confusing the scientists about its existence and the theory of general relativity.
