How is gravitational lensing related to dark matter and what role does it play in understanding the distribution of dark matter in the universe?
Gravitational lensing occurs when the gravity of massive objects, like dark matter, bends and distorts light from distant sources. By studying these lensing effects, scientists can map the distribution of dark matter in the universe. This helps us understand the role of dark matter in shaping the large-scale structure of the cosmos.

What is gravitational lensing?
Gravitational lensing is a phenomenon where light from a distant object is bent and distorted by the gravitational field of a massive object, such as a galaxy or a cluster of galaxies, that lies in between the distant object and the observer. This bending of light can create multiple images of the distant object, distort its appearance, or even magnify it. Gravitational lensing is a powerful tool for studying the distribution of dark matter in the universe and for discovering distant galaxies and objects.
Does light have gravity and if so, how does it affect the behavior of light in the universe?
Light does not have mass, so it does not have gravity in the traditional sense. However, according to Einstein's theory of general relativity, light can be affected by gravity. This is known as gravitational lensing, where light bends around massive objects like stars and galaxies, altering its path. This phenomenon can distort the appearance of distant objects and provide insights into the distribution of mass in the universe.
How can the curvature of space be measured?
The curvature of space can be measured using techniques such as gravitational lensing, cosmic microwave background radiation, and the study of the large-scale structure of the universe. These methods allow scientists to observe how light and matter are affected by the curvature of space, providing valuable insights into the shape and geometry of the universe.
Which thing in this universe can bend the light?
Anything with mass. The larger the mass, the greater the degree that light can be bent or deflected. In reality, you "could" observe it everyday, but the amount is so small you would never see it.
How are photons affected by gravity?
Photons are affected by gravity because they have energy and momentum, which can be influenced by gravitational fields. Gravity can cause photons to change direction or lose energy as they travel through space. This effect is known as gravitational lensing.

How is gravitational lensing related to dark matter and what implications does this relationship have for our understanding of the universe?
Gravitational lensing is the bending of light by gravity, and it can be used to study dark matter because it affects how light is bent. The relationship between gravitational lensing and dark matter helps scientists map the distribution of dark matter in the universe. This can provide insights into the structure and evolution of the universe, as well as help us understand the role of dark matter in shaping the cosmos.
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.
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.
What is the method used view distant galaxies?
Gravitational lensing
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 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.

How does the effect of gravity on light influence the behavior of electromagnetic radiation in space?
The effect of gravity on light can cause it to bend or curve as it travels through space, a phenomenon known as gravitational lensing. This can distort the path of electromagnetic radiation and affect how we observe distant objects in the universe.
