Scientists had thought that it was possible for gravity to enter the higher dimensions (those beyond the four that humans experience – up / down, side by side, forward / backward, time) even though light do not do it. If this happens, the force of gravity would lose more of its energy than light while crossing the space. But the comparison of the light and gravitational waves resulting from this collision between neutron stars showed that this did not happen. "Data-reactid =" 23 "> In a document first uploaded on November 1 on the pre-print server arXiv (which was first reported by Live Science) ScienceAlert), researchers have announced that they had found no evidence of "gravitational leakage." Scientists thought it was possible to penetrate gravity into the high dimensions (those beyond the four that live humans – from top to bottom, left right, forward / backward, the time If this happened, the force of gravity would lose more of its energy than light while crossing the space, but the comparison of the light and gravitational waves of the collision between stars to neutrons showed that this did not happen.

The gravity of our entire dimension seems to remain where it is, as Albert Einstein had predicted in his theory of general relativity.

If there was a "massive graviton", the gravitational waves would also have a mass, and if these waves had a mass, they would show signs of momentum, unlike the light particles, which are massless. It would also be a violation of general relativity. But, again, this has not been the case.

Overall, the researchers found that Einstein's theories of gravity remain fundamentally intact. One day it could change. But this is not yet the case, even after two neutron stars have collided.
