Sentences with phrase «light in the gravitational field»

Lens - like action of a star by the deviation of light in the gravitational field.

And so Einstein's brief paper, «Lens - like action of a star by the deviation of light in the gravitational field,» was published in the Dec. 4 Science.

Kramer and his colleagues are trying to do just that: «We can test many different aspects, among them the characteristics of gravitational waves, the propagation of light in gravitational fields, the fact that clocks go slower near massive bodies, the curvature of spacetime, etc..

Not exact matches

For instance, if the earth were slightly larger, hydrogen, a light gas, could not escape into the atmosphere at its prescribed rate (due to an increase in the earth's gravitational field), and over time would build up and cause life to cease.

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).

The signals generated by the magnitude - 9.1 quake that struck Japan were barely one - billionth g, the amount of Earth's gravitational field at sea level, but they traveled at the speed of light and were detected at seismometers hundreds of kilometers away, the researchers report today in Science.

Just as light waves can be polarized horizontally or vertically depending on which way the electromagnetic field in them jiggles, gravitational waves can be polarized in two ways, according to general relativity, Will says.

So when a dim star in our galaxy passes almost directly between Earth and a second star, the gravitational field of the intervening «lens» star bends and magnifies light from the background star, a process called gravitational microlensing.

And much as one can apparently detect a black hole by seeing how it bends the light attempting to pass by it, I felt I could detect the value of Stephen's work by its gravitational pull on neighboring scientists in his field.

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...

This testing is especially so in regions close to a black hole, according to Chen, because the current evidence for Einstein's general relativity — light bending by the sun, for example — mainly comes from regions where the gravitational field is very weak, or regions far away from a black hole.

The recent blockbuster Interstellar is based on premises that Einstein made technically plausible, if not (yet) technologically feasible: that by travelling close to the speed of light, or moving in an intense gravitational field such as that of a black hole, we age more slowly than those we leave behind on Earth (see diagram).

This is that light moving in a gravitational field can experience small wavelength changes (redshifts and blueshifts).

Gravitational lens, matter that through the bending of space in its gravitational field alters the direction of light paGravitational lens, matter that through the bending of space in its gravitational field alters the direction of light pagravitational field alters the direction of light passing nearby.

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.

In these cases, each planet's gravitational field bends and focuses light from a star lined up behind it, much as the glass lens in a telescope bends and focuses starlighIn these cases, each planet's gravitational field bends and focuses light from a star lined up behind it, much as the glass lens in a telescope bends and focuses starlighin a telescope bends and focuses starlight.

For example, in order to test the prediction that light from a distant star would be «bent» by the gravitational field of the sun, one had to make certain assumptions regarding the behavior of light — namely, that it takes the «straightest» path between any two points.
