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.

Does gravity affect light?
Yes as explained in the theory of relativity Yes. Light is affected by gravity, but because light travels so fast, the effect is not noticeable under most conditions. As light passes by something with mass its path bends toward the object in what is called gravitational lensing. We have observed this effect around massive galaxies as the light from galaxies behind them is distorted.
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 Major discoveries did the hubble telescope find?
Many, many, many. Just a few include: Information about planets around other stars. Detailed observations of the Shoemaker-Levi comet crash into Jupiter, giving information about comets and Jupiter. Detailed distances to far away galaxies, allowing refinement of the speed that the universe expands, leading to the discovery of dark energy. Detailed observations of gravitational lensing, leading to dark matter. Discovery that ancient galaxies are different and more irregularly shaped than current galaxies.
How can you see an object that is not luminous and does not produce its own light?
Light can reflect off it - that is how we see all the planets in out solar system.It can bend light (Einstienisn lensing) if it is massive enough.You can see changes in light/energy from objects that go behind it (eclipsing)
Why do astronomers propose that the Milky Way Galaxy contains a lot of dark matter?
Oh, well this is an interesting question, and a fun one to answer!Basically, dark matter is proposed to exist because of the observations of interacting masses both within and between galaxies. (Note that it is not just the Milky Way that is proposed to contain dark matter; rather, 84% of the universe is hypothesized to be made of dark matter.) Basically, the total mass of all the stars and planets and other celestial objects should not be enough to cause the effects of gravitational lensing, solar revolution, etc. that are observed. Therefore, dark matter is proposed to exist; a type of matter that only interacts with gravitons and W bosons (only interacts with gravity and the weak force) and that is entirely undetectable.
What is gravitational lensing?
Gravitational lensing is the bending of light around a massive object due to gravity.
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."
Why do stars look distorted like a full house mirror when you when you are orbiting a black hole?
This is a phenomenon called gravitational lensing. Light, like matter, is affected by gravity and bends as it passes near an object with mass. Because light travels so fast, however, the lensing is generally not very noticeable except with extremely strong gravity such as that around a black hole.
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'
What can happen to photons approaching a black hole?
Light that passes near a black hole but does not cross the event horizon is bent toward it in what is called gravitational lensing. The closer the light passes to the black hole, the more it is bent. For someone with an up-close view, this lensing would result in a highly distorted image of whatever is behind the black hole. Photons that cross the event horizon are lost inside of it forever, and their energy is added to the mass of the black hole.
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.
