The census results of 200,000 stars confirmed that the mysterious force that tears the universe at an increasing rate comes from dark energy. This 5-year survey result of the galaxy further supports the current popular mysterious dark energy operation theory-dark As a monotheistic constant force, Neng Tong uniformly affects the universe and controls the rapid expansion of the universe. However, proponents of the theory of gravity insist that dark energy has not caused the universe to expand, and galaxies are pulled by gravity and separated from neighboring galaxies Gravity is what causes space to separate and causes the universe to expand further. Which of the following, if true, would most weaken the views of the proponents of gravity? ['Many research results have confirmed the existence of dark energy.', 'Astronomers observe that the expansion of the universe is currently slowing.', 'The force that causes the galaxy to be pulled away from neighboring galaxies by dark energy.', 'Whether gravitational theory can be used to explain the expansion of the universe needs further study.']
