  3. CL0024+17 - Wikipedia

    en.wikipedia.org/wiki/CL0024+17

    The cluster CL0024+17 is a cluster of galaxies located in Pisces, and about 4 billion light years distant. Cl 0024+17 is allowing astronomers to probe the distribution of dark matter in space . The blue streaks near the center of the image are the smeared images of very distant galaxies that are not part of not much but a little tiny part the ...

  4. Introduction to general relativity - Wikipedia

    en.wikipedia.org/wiki/Introduction_to_general...

    The equivalence between gravitational and inertial effects does not constitute a complete theory of gravity. When it comes to explaining gravity near our own location on the Earth's surface, noting that our reference frame is not in free fall, so that fictitious forces are to be expected, provides a suitable explanation. But a freely falling ...

  5. Speed of gravity - Wikipedia

    en.wikipedia.org/wiki/Speed_of_gravity

    Therefore, the movements of the celestial bodies should be modified in the order v/c, where v is the relative speed between the bodies and c is the speed of gravity. The effect of a finite speed of gravity goes to zero as c goes to infinity, but not as 1/c 2 as it does in modern theories.

  6. Gravitational lens - Wikipedia

    en.wikipedia.org/wiki/Gravitational_lens

    In general relativity, light follows the curvature of spacetime, hence when light passes around a massive object, it is bent. This means that the light from an object on the other side will be bent towards an observer's eye, just like an ordinary lens. In general relativity the path of light depends on the shape of space (i.e. the metric).

  8. Gravitational redshift - Wikipedia

    en.wikipedia.org/wiki/Gravitational_redshift

    The gravitational weakening of light from high-gravity stars was predicted by John Michell in 1783 and Pierre-Simon Laplace in 1796, using Isaac Newton's concept of light corpuscles (see: emission theory) and who predicted that some stars would have a gravity so strong that light would not be able to escape. The effect of gravity on light was ...
