An Earth-based sensor tuned to such an event would detect a slow, overall change in the local gravitational field
superimposed on the rapidly fluctuating signal from the primary burst itself.
The foregoing results show that numerous properties of vortical gravitational fields
manifest only if such a field is due strictly to the "electric" or the "magnetic" kind.
Its gravitational field
is thought to be so strong that nothing, not even light, can escape it.
As the craft escapes Earth's gravitational field
, however, it enters the Sun's gravitational field
To improve their estimates, the mathematicians took the gravitational fields
of all the planets except little Pluto into account, and calculated their possible combined effects on various possible orbits of 433 Eros in the distant future.
This reduction in radius is accomplished by the forces generated by a material component of the gravitational field
Kopeikin of the University of Missouri in Columbia extended those equations to the changing gravitational fields
around moving bodies, such as Jupiter.
The probe was due to orbit Eros for a year, sending back information on rock composition and mapping its magnetic and gravitational fields
from within feet of the surface.
With a lot of matter packed into a sphere about the size of the Earth, they have strong gravitational fields
The early Kaluza-Klein (K-K) theory of unification was further developed with a scalar field , which can modify both the electromagnetic and gravitational fields
In particular, they became curious about quantum fluctuations associated with gravitational fields
Instead, the team used deep circulation theories developed by Showman and Kaspi to predict what the gravitational fields
of Neptune and Uranus should look like.
The relativistic dynamical equation of motion for particles of non-zero rest masses in combined electric and gravitational fields
is given as 
They had to put aside temporarily some real-world phenomena, such as magnetic and gravitational fields
, and consider only the subtle interactions of attractive and repulsive forces between charged particles within an atom.
Scheduled for launch in November 1996 on board a Delta launch vehicle, the Mars Global Surveyor (MGS) will reach the red planet in September 1997 and perform a 24-month mission orbiting Mars and studying its surface, atmosphere and magnetic and gravitational fields
