An interesting new theory of gravity, explaining the strange motion of stars in galaxies, was proposed by a professor at the University of Amsterdam, Eric Verlinde, an expert in the field of string theory.
In 2010, Professor Verlinde surprised everyone with a new theory, according to which gravity is not a fundamental force of nature, but an emerging phenomenon that acts in the same way as temperature, increasing from the movement of microscopic particles. Only gravity arises from changes in the fundamental information particles contained in the very structure of space-time.
The fact is that stars in the outer regions of galaxies, such as the Milky Way, move around the galactic center at a speed much higher than the available mass of matter - stars, planets and interstellar gases - could provide. Physicists assumed the presence of a huge mass of dark matter, which, according to scientists, makes up 80% of the universe. However, no one has ever observed the particles of dark matter, despite constant attempts to discover this mysterious substance.
And now, according to the conclusions of Verlinde, there is no need to use dark matter in explaining the phenomenon of gravitational acceleration. His unusual theory accurately calculates the speed of rotation of stars around the center of the Milky Way, as well as the movement of stars within galaxies, writes Phys.org.
“We have evidence that the new view of gravity is consistent with observational data,” says Verlinde. "By and large, it turns out that gravity does not behave the way Einstein's theory claims." “Perhaps we are on the verge of a new scientific revolution that will radically change our view of the nature of space, time and gravity,” the scientist said.
In order to finally reveal traces of dark matter, a calorimetric electron telescope (CALET) was built. It is installed on the ISS and will study the trajectory of cosmic ray particles, measure their charge and energy.
