Why do stationary or massless photons interact with gravity?
Intense gravitational waves shock the velocity of massless objects including photons or any other electromagnetic radiation carriers, and this is linked to Einstein's general theory of relativity and the gravitational lensing effect dictated by larger objects around which light velocity vector bends but its value remains invariant.
What was Albert Einsteins major contribution to science?
As well as the oft repeated E=MC2, Einstein also produced advances in the photoelectric effect (for which he received the Nobel prize), Brownian motion, and in relativity both special and general. He was also quite active in cosmology, and predicted gravitational lensing. (Bending of light as it passes a star). He also had theories on special and general relativity.
Is gravitational potential energy is the same gravitational force?
No. Gravitational force is the pull an object experience from gravity. Gravitational energy is the energy an object has from its position in a gravitational field. An object moving up in a gravitational field gains gravitational energy.
The energy of position such as a rock on a hill is what energy?
Gravitational energy Potential energy
What is gravitational mass?
Gravitational mass is a term used in physics. The definition of gravitational mass is the mass of a body as measured by its gravitational attraction for other bodies.
Why would gravitational lensing create multiple images instead of just a distorted one?
Gravitational lensing creates two images because light from a given source is being bent around both sides of the object doing the lensing.
Why does light show gravitational lensing if it is not a state of matter?
Gravitational lensing does not depend on a the state of matter of light, rather it is an expression of the geometric curvature of space/time due to mass.
Is gravitational a word?
Yes. It is an adjective meaning "of, relating to, or involving gravitation." It is used terms such as "gravitational acceleration" and "gravitational lensing."
What is lense?
Gravitational lensing is the bending of light around a massive object due to gravity.
What is the estimated universal mass percentage of gravity-lensing dark matter?
Dark matter is estimated to be responsible for about 27% of the total mass-energy in the universe (normal matter is a bit under 5%)."Gravity-lensing" is essentially a meaningless phrase here; all mass causes gravitational lensing, so there's no such thing as "non-gravity-lensing" dark matter.
What two-word term describes the bending of light passing between celestial objects?
Gravitational lensing.
What evidence is there of the existence of dark matter?
The gravitational effects. For example, gravitational lensing; also, galaxies spin way too fast for the amount of known matter.
What has the author Christopher R Burns written?
Christopher R. Burns has written: 'Gravitational lensing of polarized sources'
Does gravitational lensing magnify distant galaxies at distances up to 13 billion light years behind galaxy clusters?
Yes. Lensing magnifies the image of galaxies behind distant galaxy clusters but also greatly distorts the image.
What has the author Gordon K Squires written?
Gordon K. Squires has written: 'Mapping the dark matter with weak gravitational lensing' -- subject(s): Physics Theses
Why do stars look like points of light?
The bending of light around a large distribution of matter, such as a cluster of galaxies is known as gravitational lensing. Gravitational lensing occurs due to the curving of space-time caused by a massive gravitational field caused by either by a large distribution of matter, such as a galaxy cluster or a black hole. This curving of space-time causes light rays passing through to bend around the gravitational center. A very large amount of matter is needed in order for the lensing effect to occur, typically in the range of a hundred to a thousand galaxies. The bending caused by a single star would be negligible.
What do black holes emit that could allow them to be detected from the earth?
Black holes does emit radiation, but they cannot be detected from earth. We use gravitational lensing to "see" the black holes.
