2. Gravitation (book) - Wikipedia

   en.wikipedia.org/wiki/Gravitation_(book)

   The book is still considered influential in the physics community, with generally positive reviews, but with some criticism of the book's length and presentation style. To quote Ed Ehrlich: [4] 'Gravitation' is such a prominent book on relativity that the initials of its authors MTW can be used by other books on relativity without explanation.

3. Yvonne Choquet-Bruhat - Wikipedia

   en.wikipedia.org/wiki/Yvonne_Choquet-Bruhat

   Yvonne Choquet-Bruhat (French: [ivɔn ʃɔkɛ bʁy.a] ⓘ; born 29 December 1923) is a French mathematician and physicist.She has made seminal contributions to the study of general relativity, by showing that the Einstein field equations can be put into the form of an initial value problem which is well-posed.

4. Two-body problem in general relativity - Wikipedia

   en.wikipedia.org/wiki/Two-body_problem_in...

   The two-body problem in general relativity (or relativistic two-body problem) is the determination of the motion and gravitational field of two bodies as described by the field equations of general relativity. Solving the Kepler problem is essential to calculate the bending of light by gravity and the motion of a planet orbiting its sun.

5. Euler's three-body problem - Wikipedia

   en.wikipedia.org/wiki/Euler's_three-body_problem

   The Euler three-body problem is known by a variety of names, such as the problem of two fixed centers, the Euler–Jacobi problem, and the two-center Kepler problem. The exact solution, in the full three dimensional case, can be expressed in terms of Weierstrass's elliptic functions [ 2 ] For convenience, the problem may also be solved by ...

6. Penrose–Hawking singularity theorems - Wikipedia

   en.wikipedia.org/wiki/Penrose–Hawking...

   A singularity in solutions of the Einstein field equations is one of three things: Spacelike singularities: The singularity lies in the future or past of all events within a certain region. The Big Bang singularity and the typical singularity inside a non-rotating, uncharged Schwarzschild black hole are spacelike.

7. Hierarchy problem - Wikipedia

   en.wikipedia.org/wiki/Hierarchy_problem

   This problem, called the cosmological constant problem, is a hierarchy problem very similar to that of the Higgs boson mass problem, since the cosmological constant is also very sensitive to quantum corrections, but it is complicated by the necessary involvement of general relativity in the problem. Proposed solutions to the cosmological ...

8. List of equations in gravitation - Wikipedia

   en.wikipedia.org/wiki/List_of_equations_in...

   In the weak-field and slow motion limit of general relativity, the phenomenon of gravitoelectromagnetism (in short "GEM") occurs, creating a parallel between gravitation and electromagnetism. The gravitational field is the analogue of the electric field , while the gravitomagnetic field , which results from circulations of masses due to their ...

9. Newton's law of universal gravitation - Wikipedia

   en.wikipedia.org/wiki/Newton's_law_of_universal...

   The n-body problem is an ancient, classical problem [19] of predicting the individual motions of a group of celestial objects interacting with each other gravitationally. Solving this problem – from the time of the Greeks and on – has been motivated by the desire to understand the motions of the Sun, planets and the visible stars.
