A team from the University of Geneva has developed a new method to test the validity of the equations of Leonhard Euler and Albert Einstein at the edge of the universe. The equations of Euler describe the movements of celestial objects, while Einstein’s theory of general relativity explains how celestial objects distort the universe. The team’s method considers time distortion, which has not been used before, to test whether these equations can explain the mysterious phenomena of dark matter and the acceleration of the universe’s expansion. If time distortion does not correspond to the speed of galaxies calculated with Euler’s equation, then it is not valid. If it does not equal the sum of time and space, then Einstein’s model does not work. The team’s research will contribute to several missions, including the EUCLID space telescope, the Dark Energy Spectroscopic Instrument and the international SKA giant radio telescope project.
