The strong equivalence principle requiring both of the above.

The system will provide them a chance to test the strong equivalence principle in a strong gravitational field.

Some have argued that only general relativity satisfies the strong equivalence principle.

At this point the strong equivalence principle supplies a key ingredient to understanding curved space-time.

Notice that the strong equivalence principle says that there is no local experiment to tell these two situations apart.

The strong equivalence principle suggests the laws of gravitation are independent of velocity and location.

Application of the strong equivalence principle provides the basis for a definition of parallel transport in curved space time.

It becomes the strong equivalence principle (SEP) which states the following:

What about the Strong Equivalence Principle?

(See also strong equivalence principle.)

Thus, the strong equivalence principle can be tested by searching for fifth forces (deviations from the gravitational force-law predicted by general relativity).

Precise observations of the perihelion shift of Mercury constrain other parameters, as do tests of the strong equivalence principle.

Einstein's theory of general relativity (including the cosmological constant) is thought to be the only theory of gravity that satisfies the strong equivalence principle.

This is the Strong Equivalence Principle (SEP).

Another part of the strong equivalence principle is the requirement that Newton's gravitational constant be constant in time, and have the same value everywhere in the universe.

This would violate the strong equivalence principle that the laws of gravitation are independent of velocity and location, a principle considered fundamental by many theoretical physicists.

If observed, the Nordtvedt effect would violate the strong equivalence principle, which indicates that an object's movement in a gravitational field does not depend on its mass or composition.

Other modern theories, such as string theory, quintessence, and various forms of quantum gravity, almost all predict a violation of the Strong Equivalence Principle at some level.

Two new principles were suggested, the so-called Einstein equivalence principle and the strong equivalence principle, each of which assumes the weak equivalence principle as a starting point.

A future satellite experiment, SEE (Satellite Energy Exchange), will search for fifth forces in space and should be able to further constrain violations of the strong equivalence principle.

A stronger version of the equivalence principle, known as the Einstein equivalence principle or the strong equivalence principle, lies at the heart of the general theory of relativity.

The strong equivalence principle suggests that gravity is entirely geometrical by nature (that is, the metric alone determines the effect of gravity) and does not have any extra fields associated with it.

One way is to search for a fifth force with tests of the strong equivalence principle: this is one of the most powerful tests of Einstein's theory of gravity; general relativity.

If an observer measures a patch of space to be flat, then the strong equivalence principle suggests that it is absolutely equivalent to any other patch of flat space elsewhere in the universe.

These include: Newton's equivalence principle, the weak equivalence principle, the gravitational weak equivalence principle, Einstein's equivalence principle and the strong equivalence principle.
