Eistein is right, neutron stars make space-time twists

Albert Einstein and fiction writers have predicted the space-time twisting phenomenon of neutron stars, the most dense material that can be observed in the universe. And now is proof of that.

The twisting effect is described as follows: Imagine a heavy bowling ball, placed on a rubber net. If we rotate the ball, it will pull the rubber sheet to follow. Likewise, when the earth turns, it pulls out - time moves by itself, though extremely slow.

Astronomers from NASA and the University of Michigan say the twisting phenomenon is expressed in the form of faint, wavy iron vents around the stars.

Sudip Bhattacharyya, a member of the research team, said the finding is not entirely unexpected, but it is meaningful for answering basic questions of physics.

Heavy neutron stars are equivalent to stuffing the sun into a sphere the size of a city. Therefore, only a few cups of their materials are heavier than Mount Everest. Astronomers use these dwarf stars as a natural laboratory to find out how much the matter can be concentrated under the maximum yield that nature can have.

In two parallel studies, NASA and European astronomers observed three pairs of neutron stars. They also looked at the spectral currents of hot iron atoms rotating in a plate just outside the surface of neutron stars at a rate of 40% of the speed of light.

Typically, the measured spectrum of these superheated iron atoms will manifest as a symmetrical peak. However, the team's results are a skewed peak, indicating a distortion due to the relative effect. The rapid movement of the gas mass (and the gravitational gravitational pull) caused this spectrum to fade, sliding to a longer wavelength.
