Sentences with phrase «strong gravitational fields»

The discovery provides the first confirmation of general relativity in very strong gravitational fields (as opposed to the weak fields of Earth and other planets).

However, these tests do not constrain how well the very strong gravitational fields produced by merging neutron stars obey this theory.

Albeit frightening, their action is reasonably straightforward: black holes have such strong gravitational fields that nothing, not even light, can escape their grip.

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).

Soon after Einstein published his theory describing gravity as warps in space - time, the German astronomer Karl Schwarzschild used the theory to show that if a large star were squeezed into a small enough point, it would create such a strong gravitational field that nothing, not even light, could...

All you would have to do is use an extremely strong gravitational field, like that of a black hole, to bend space - time.

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.

Around a black hole, however, the effect would be much more noticeable because of the stronger gravitational field.

«We are directly measuring the motion of matter in a strong gravitational field near to a black hole,» says Ingram.

This is the first time that the Lense - Thirring effect has been measured in a strong gravitational field.

Einstein's Theory of General Relativity predicts that light coming from a strong gravitational field gets stretched out, or «redshifted.»

«In principle, these stars could test general relativity, because they get into a very strong gravitational field at the central black hole,» Ghez says.

A number of places in the Indian Ocean, such as Madagascar, Mauritius and the Seychelles, Maldives, and Lakshadweep islands, are known to display a slightly stronger gravitational field than expected.

As the argument goes, as an observer approaches the horizon, time slows down, since clocks tick slower in a strong gravitational field.

That change caused the minor planet to travel very close to the white dwarf, where the star's strong gravitational field ripped the minor planet apart into gas and dust.

The black holes that power quasars probably started their lives in miniature and grew exponentially by accretion — whereby matter close to a black hole can not escape the strong gravitational field and is ultimately pulled into the black hole.

Occasionally, when the stars are aligned just right, this warping of the fabric of the universe results in a phenomenon known as gravitational lensing, wherein the strong gravitational field of a foreground object acts as a lens that «bends» light from an object in the background and allows scientists to catch a glimpse of what might otherwise have remained invisible.

At once scientists seized on double pulsars as a way to subject General Relativity to its hardest test yet in the presence of a strong gravitational field.

The degree of broadening implies that the gas is moving around at high speed, a result of the strong gravitational field of the black hole.

A stronger gravitational field will produce a lower, denser, warmer surface than a weaker gravitational field since the amount of solar energy retained by the atmosphere will be focused into a smaller volume and that amount of energy will be determined by the amount of mass available to absorb it at any given level of solar irradiation.

In a very strong gravitational field?

Not exact matches

Apple has the strongest «gravitational field of loyalty,» Forrester Research analyst Charles Golvin said.

By studying gravitational waves, they can now explore extreme conditions in which the energy in an object's gravitational field accounts for most or all of its mass — the realm of strong gravity so far explored by theorists alone.

The region of space around an object where a satellite could orbit indefinitely is called the Hill sphere, roughly defined as where the object's gravitational field is stronger than that exerted by another object outside the sphere.

Because of that equivalence principle, then, the same must be true for gravity: As a gravitational field grows stronger, time slows even more.

Cohen and others think the cure could be hypergravity: a force stronger than Earth's gravitational field delivered to astronauts on a centrifuge.

There's a chance the supernova would collapse into an even more enigmatic state — a black hole, which has a gravitational field so strong that not even light can escape.

General relativity has been tested with great precision within the solar system, and in binary pulsar systems where gravitational fields are very strong, but never on large scales where gravity's pull is weak.

If detected, Chen's effect — a derivative of the gravitational Faraday effect — would provide strong evidence of the correctness of Einstein's general relativity theory in the «strong - field regime,» or an environment in close proximity to a black hole.

This detection has, in a single stroke and for the first time, validated Einstein's theory of general relativity for very strong fields, established the nature of gravitational waves, demonstrated the existence of black holes with masses 30 times that of our sun, and opened a new window on the universe.

-- Einstein's landmark theory of general relativity is holding strong, even at the doorstep of the most extreme gravitational field in our galaxy.

Although GR has been accurately tested in weak gravitational fields, it remains largely untested in the general strong field cases.

Indeed, sometime after the tenuous gas of the Solar nebula began collapsing into the proto - Sun within its host molecular cloud, a strong magnetic field developed that was instrumental in transporting rotational energy away from its core region in bi-polar jets of gas so that centrifugal forces created by the nebula's collapse did not grow so much as to halt continuing gravitational contraction.
