The statement that "the attraction of two large stars leads to gravity" reverses the causal relationship. According to general relativity, gravity is essentially a manifestation of spacetime distortion caused by mass, not a result of celestial attraction . Document 1 clearly states that "the main reason for the formation of celestial systems is not gravity, but spacetime distortion caused by mass". The mass of stars bends the surrounding spacetime, and this curved spacetime geometry causes the "attraction" phenomenon we observe.

Taking the solar system as an example, the reason planets orbit the sun is not that the sun "pulls" the planets, but that the sun's mass distorts the surrounding spacetime. Planets move along the shortest path (geodesic) in this curved spacetime . Similarly, the mutual orbital motion between neutron stars and brown dwarfs mentioned in Document 5 is also a result of spacetime distortion caused by their respective masses, not the other way around where their attraction generates gravity.

In classical mechanics, Newton's law of universal gravitation describes the gravitational force between two objects as proportional to the product of their masses and inversely proportional to the square of the distance between them . This also shows that gravity is a property derived from mass, not generated by the "attraction" between objects. Whether it is the general relativity perspective of spacetime distortion or the Newtonian mechanics perspective of the law of universal gravitation, gravity is an inherent phenomenon caused by mass, and the mutual attraction between stars is just a manifestation of gravity, not its cause.

So, the correct understanding should be: the mass of two large stars causes spacetime distortion, thereby generating gravity, which in turn leads to their mutual attraction. The original statement混淆了因果关系 (confuses cause and effect), so it is incorrect.
