  • Interesting fact: There is air in space, but very little of it. In fact, it is equivalent to a marble in a box 5 miles wide. Most of the gas is captured by the gravitational pull of other celestial bodies.Thanx M.Lerner
    • n gravitation The act of gravitating or tending toward a center of attraction.
    • n gravitation That attraction between bodies, or that acceleration of one toward another, of which the fall of heavy bodies to the earth is an instance. See gravity, 1. Gravitation can be neither produced nor destroyed; it acts equally between all pairs of bodies, the acceleration of each body being proportional to the mass of the other; it is neither hindered nor strengthened by any intervening medium; it occupies no time in its transmission; its force is inversely as the square of the distance; and the amount of it is such that a particle distant one centimeter from an attracting gram of matter would by the action of gravitation alone, were no other force present, fall into the center of attraction in 40 minutes and 20 seconds. Inasmuch as the masses of bodies can be measured otherwise than by their weights, namely, by their relative momentums under a given velocity, it follows that the modulus of gravitation, or the amount by which the unit mass attracts a particle at the unit distance, which is invariable, best distinguishes gravitation from every other force. The laws of the attraction of gravitation were demonstrated by Sir Isaac Newton in 1687.
    • n gravitation In philology, the tendency of sounds and syllables having little or no stress to become merged in the accented syllable, or to fall away entirely; the absorption of weaker elements.
    • n gravitation Figuratively, a prevailing tendency of mental or social forces or activities toward some particular point or result.

Seek out its great allies;
Good must find good by gravitation sure,
And love with love endure.

Does the earth gravitate? Does not all matter, aching, attract all
So the Body of me, to all I meet, or know.

See one straightforward conscience put in pawn
To win a world; see the obedient sphere
By bravery's simple gravitation drawn!

But gravitation's law, of course,
As Isaac Newton showed it,
Exerted on the cheese its force,
And elsewhere soon bestowed it.
In fact, there is no need to tell
What happened when to earth it fell.

In science:

The gravitational energy-momentum is given by equation of motion of gravitational gauge field, it is also a conserved current.
Gauge Theory of Gravity
We can see again that, for matter field, its inertial energy-momentum tensor is also different from the gravitational energy-momentum tensor, this difference completely originate from the influences of gravitational gauge field.
Gauge Theory of Gravity
It can be seen that the vector field can also directly couple to arbitrary number of gravitational gauge fields, which is one of the most important properties of gravitational gauge interactions.
Gauge Theory of Gravity
In gravitational gauge theory, the system has local gravitational gauge symmetry.
Gauge Theory of Gravity
But, as we have studied in previous chapters, the inertial energymomentum is not equivalent to the gravitational energy-momentum in gravitational gauge theory.
