The electromagnetic interaction and the gravitational interaction decreased in intensity with the square of the distance.
The gravitational interaction affects all particles with mass, while the electromagnetic interaction affects only electrically charged particles, the strong interaction affects only hadrons, and the weak interaction is most prominent in connection with leptons.
The interaction between real energies is gravitational interaction.
The galaxy seems warped too, the flaring of its edges no doubt a result of gravitational interaction with its Messier neighbors.
The most plausible explanation is that some kind of gravitational interaction with two other stars in the region ejected the massive body.
The problem of correctly defining the source of the gravitational power heating the Bok globules remained unsolved in absence of a theory of the gravitational interaction able to specify the rate at which the gravitational waves hit the particles.
Theorists have simulated such a situation, finding that if our Sun originated in at least a moderately dense birth cluster (with a core packing 300 solar masses or more in a single cubic light-year), the gravitational interaction of our system with other stars could have produced IOC objects like Sedna and 2012 [VP.
On the other hand, it has been reported [6] that propagation of fermions in curved space-time generates gravitational interaction due to the coupling of its spin with space time curvature connection, and causes a CPT violating term in the Lagrangian, generating an asymmetry between the left-handed and the right-handed partners under the CPT transformation.
It was seen that a Yukawa-type potential exists at r = R for gravitational interaction as well as at r = [r.
Astronomers believe IC 3583 is a Type II irregular galaxy - one that was created as a result of a gravitational interaction with another nearby galaxy.
In this case, the planet is directly embedded in the disk itself, and gravitational interaction with the outer spiral wake induces rapid inward migration.
