In physics,
Albert Einstein recast the theory as space itself being sucked into
each mass (General Relativity, GR), calibrating his formula to virtually match
Newton's excepting extreme circumstances,
but with some consequences, such as Electromagnetic Radiation passing near a massive
object being affected just as a passing object would be.
The term These theories are phenomenally successful: for example, their reliability and precision has made space navigation as we know it possible, and the theorized bending of light has been observed. Yet they have failed to explain some observations: - Stars in galaxies do not orbit the galaxy in accordance to gravitational theory, given the apparent masses of the galaxies' constituent stars and clouds.
- Gravity would make the universe accelerate inwardly (or given its current expansion, would make that expansion decelerate), but observations suggest it is doing the opposite.
Scientists have sufficient faith in gravitational theory that they cite it to assert galaxies must include matter that has yet to be seen (Dark Matter), and that there must be an as-yet-unexplained outward force at work in the universe (Dark Energy). Alternately, attempts have been made to further refine gravitational theory to explain these observations (Modified Newtonian Dynamics and DGP Gravity). physics,relativity)Referenced by:
