Although the general theory of relativity (GR) predicts that gravitational waves (GWs) have exactly the same propagation velocity as electromagnetic (EM) waves, many theories of gravity beyond GR expect otherwise. Accurate measurement of the differen

Aiming at the problem that the vibration of space robot will reduce the dynamic accuracy of robot, a method of vibration suppression of space robot through trajectory planning is proposed. First, the joint was simplified to a linear torsion spring, a

We investigate the Baryonic Faber-Jackson Relation (BFJR), examining the correlation between baryonic mass and velocity dispersion in galaxy groups and clusters. Originally analysed in elliptical galaxies, the BFJR is derivable from the empirical Rad

Recent studies reveal a radial acceleration relation (RAR) in galaxies, which illustrates a tight empirical correlation connecting the observational acceleration and the baryonic acceleration with a characteristic acceleration scale. However, a disti

Abstract In the centered surround system S ( 2 ) { P , Γ } $S^{(2)} \{P,\varGamma \}$ , we establish the following gravity inequalities: ( 1 + 5 2 π e 2 1 − e 2 ) ( 2 π | Γ | ) 2 ≤ 1 | Γ | ∮ Γ 1 ∥ A − P ∥ 2 ≤ ( 1 + 16 − π 4 π
