Einstein's theory of relativity still works in extreme conditions: Space: Nature World News

Albert Einstein has once again proved that scientists are attacking the theory of general relativity – and carry it to the stars.

Theory of General Relativity

Einstein's Famous Theory states that all objects fall at the same speed into the same gravitational field, provided that there is no resistance in the air. For example, a bowling ball and a ball falling from the leaning tower of Pisa will hit the ground exactly at the same time, regardless of differences in mbad and composition.

Up to now, however, it has not been proven

A Starry Experiment

In a new study published in the journal Nature an International Team of Scientists centered on a triple star system at 4,200 light-years. This system consists of a neutron star (a pulsar) orbiting a white dwarf, and this pair in turn turns into orbit around another white dwarf.It is important to remember that the objects in orbit are simply in free fall. never touch the surface as it moves at the same rate as the object that pulls it is curved. Here's how a satellite turns around the Earth

The Conversation explains that according to the theory of general relativity, the pulsar and white dwarf's acceleration should be the same as that of the free fall towards the planet. another white dwarf. This is despite their differences in mbad, composition and self-gravity.

Over a six-year observation period, the researchers built models of the pair's orbits, trying to see if there is a difference between the behavior of the two stars. They found negligible differences, showing how Einstein's theory is still the best existing model of how gravity works.

"There is a difference, it is not more than three parts in a million", coauthor Nina Gusinskaia, PhD student at the University of Amsterdam, has stated in a statement at the University of British Columbia. "Now, anybody with an alternative theory of gravity has an even narrower range of possibilities that their theory needs to integrate, to match what we have seen."

The theory flourishes in another galaxy, also

A separate study, published in the journal Science last June, reveals that the theory of general relativity has proved its worth in the world. badysis of a neighboring galaxy

. can distort the space-time around her, including light, according to Gizmodo. In the study, the team was able to prove the accuracy of general relativity by measuring how much the galaxy ESO 325-G004 deforms the light that pbades through it.
