Topic: Gravity well


  
  Gravity - Wikipedia, the free encyclopedia
The effective force of gravity decreases as the distance from the equator decreases, due to the rotation of the Earth, and the resulting centrifugal force and flattening of the Earth.
Gravity is small unless at least one of the two bodies is large or one body is very dense and the other is close by, but the small gravitational interaction exerted by bodies of ordinary size can fairly easily be detected through experiments such as the Cavendish torsion bar experiment.
Speed of gravity: Einstein's theory of relativity predicts that the speed of gravity (defined as the speed at which changes in location of a mass are propagated to other masses) should be consistent with the speed of light.

 Gravity Probe B -- Facts, Info, and Encyclopedia article   (Site not responding. Last check: 2007-10-26)
Gravity Probe B is a relativity (Rotating mechanism in the form of a universally mounted spinning wheel that offers resistance to turns in any direction) gyroscope experiment funded by (An independent agency of the United States government responsible for aviation and spaceflight) NASA.
Also important was a well understood motion in the sky, which was helped by the fact that this star emits relatively strong (A radio wave used to transmit and receive messages) radio signals.
Gravity Probe B marks the first time in history that a university has been in control of the development and operations of a space satellite funded by NASA.

A simple gravity well that is familiar to most students is the coin well used by charities to collect donations.
The gravity well can be placed on an overhead projector, and since it is transparent, the three-dimensional motions of the balls seen as two-dimensional orbits.
A demonstration that is easy to make, and operates like a gravity well, is as follows: Take a piece of mylar (the stuff used for insulating windows in the winter), stretch it over the top of a circular rim, and attach it to the rim.

Gravity is defined as a force that causes two objects of either the same or different mass to be attracted to the other (Nave, 2002).
Gravity mass is proportional to the object that is in its field.
The gravity well in a fl hole is so immense the even the electromagnetic wave forces would feed in on itself as its gravity wave in a perpetual cycle.

 Interdictor Class Cruiser
With the development of the gravity well projector, we were just a single step away from creating a new weapon in the fight against terrorist attacks.
Using the gravity well technology, Sienar Fleet Systems had created the Interdictor or "Immobilizer 418" Cruiser whose primary purpose is to set up an artificial gravity well in battle zones and high security areas.
Once a gravity well is placed, it is difficult to move, as it is subject to similar laws of inertia as actual gravitic bodies.

Gravity Probe B (GP-B) is a satellite-based mission to measure the stress-energy tensor (the distribution, and especially the motion, of matter) in and near Earth, and thus to test related models; in application of Einstein's general theory of relativity.

 A Gravity Assist Primer
This scenario is analogous the velocity of a spacecraft being added to the velocity of the massive speeding planet, and "rebounding" with a higher velocity still (although the spacecraft's "rebound" is a gravitational, rather than a mechanical, interaction, like in the baseball analogy).
On the other hand, using a gravity assist, a spacecraft comes up and steals some angular momentum during a single flyby of a planet in motion, removing momentum from that planet.
Gravity assist is really much more like a baseball connecting with a fast-moving bat than it is like a slingshot.

 Gravity
Gravity is the weakest of the four universal forces which also include nuclear force, weak radiation force, and electromagnetism.
Gravity is the force exerted by any object with mass on any other object with mass.
Gravity is ubiquitous, omnipresent and causes objects to accelerate towards the centers of other objects exerting gravitational attraction (like the center of the Earth).

 To prevent Escape into Hyperspace
This is done by simply placing gravity wells close enough to a ship that it is virtually impossible to maike the jump to hyperspace.
While gravity well projectors are impressive weapons under the correct circumstances, they have their limitations.
A gravity projector can be turned off with no delay, but the capacitors take eight rounds to shunt the power and completely recycle, meaning that the gravity well operator must wait eight rounds before placing another gravity well without risking damaging the generator.

Well, in order to create artificial gravity, the ship has to have a space warp generator.
NOTE 1: Due to the creation of the gravity field, the ship would need to stay on a set navigation course, to prevent any mishaps due to the new gravity wells.
One way to minimize such an effect, would to generate gravity well that only acted within the confines of the vessel, perhaps built into each floor sub-level, and acting only for a distance of 5cm from the base of the floor, but with a constant pull from the roof of the level, to the floor.

 Gravity
In this scenario, gravity is driven by the absence of radiation pressure within material bodies causing a positive pressure on the matter particles driven by ordinary vacuum quanta.
Gravity, hence, may be a characteristic of the interaction (or lack thereof) of long-wavelength quanta with matter.
Gravity is, therefore, an effect of the dampening of the electromagnetic field by a piece of matter.

Well, I thought you might be -- and so am I. I confess that I'm possessed by the enthusiasm of the convert.
the prism of Gravity's Rainbow refracts the whole spectrum contained in the white light of this central enigma, from the infrared heat of carnal lusts to the yellows of jaded decadence to the unseen ultraviolets of Satoric communion.
One of the most powerful manifestations of this theme is that of the mundane or the vulgar being translated to a higher level of being, whether it be acts of sex into acts of communion, the Rocket into a vehicle of Salvation, or coal tars into iridescent dyes: "We passed over the coal tars.

 sciforums.com - Alternate means to leaving gravity well, as opposed to launches
If we are to ever seriously build an interstellar, or even intra system ships with any efficiency, we are going to need a spaceyard- a platform, or station in orbit where we can build without wasting incredible amounts of fuel and materials, just to leave orbit.
With no gravity, and an enviable amount of surface space, it would be a perfect base of operations for launching.

This LSE isn't in place of the ESE fiasco, as the ESE group is that of an Earth to space solution which is bound to eventually work as their horrifically spendy bugs are resolved over a few decades, especially after investing hundreds of billions it had better work.
Instead of relying upon one tether anchor point as with the ESE (the all or nothing scenario) is suggesting, there's be at least two, or better yet is having three, although preferably a four tether operation is for the best.
BTW; flywheels located at near zero gravity of nearly any dimension are certainly possible and, if those were seriously loaded with moon dirt at 3410 kg/m3, say of something of 100 meters in diameter, perhaps a circumference placement volume of at least 1000 m3 should represent a fairly respectable initial amount of energy storage.
