There are 18 slides covering the theory behind the precession of hydrogen nuclei, how RF pulses make the nuclei change their spin state and how the subsequent relaxation allows images to be created.

It is believed that the PETM was likely initiated by changes of the orbital parameters of the Earth (eccentricity, obliquity and precession of axis) causing an increase in the intensity and distribution of solar radiation reaching the earth (Sexton et al, 2011).

[25] Also the observed position angles of the stars are also subject to small cumulative changes (additional to position angle changes caused by the Precession of the Equinoxes), as first determined by W. H. van den Bos in 1926.

By assuming that the sun was spherical, Albert Einstein (father of the Theory of General Relativity) explained with precision a variation in the orbit of Mercury, the so - called precession of the perihelion — a phenomenon that Newton's theory of gravity could not explain.

Four years of data track the spin precession of a pulsar orbiting a second pulsar, providing a positive test of general relativity in a strong gravitational field.

The double pulsar PSR J0737 — 3039A / B consists of two neutron stars in a highly relativistic orbit that displays a roughly 30 - second eclipse when pulsar A passes behind pulsar B. Describing this eclipse of pulsar A as due to absorption occurring in the magnetosphere of pulsar B, we successfully used a simple geometric model to characterize the observed changing eclipse morphology and to measure the relativistic precession of pulsar B's spin axis around the total orbital angular momentum.

But geodetic precession had already been confirmed to nearly this level of accuracy in measurements of laser light bouncing off mirrors on the Moon, and the frame - dragging result is no more accurate than an estimate extracted from measurements of the precession of the orbits of the Laser Geodynamics Satellites (LAGEOS) launched in 1976 and 1992.

One of the first rigorous tests of general relativity was an observation of the precession of Mercury's orbit around the sun.

The precession of the equinoxes is caused by the differential gravitational forces of the Sun and the Moon on the Earth.

The resulting theory, though founded on quite different principles and developed in an independent fashion from Einstein's theory, nevertheless gives predictions that are identical to the latter's, within observable limits, for each of the four classic tests of gravitational theories (i.e., precession of the perihelion of Mercury, redshift of light emitted by a massive body, the bending of light - beams in a strong gravitational field, and the apparent slowing of the speed of light propagation near massive bodies).
