Why do astronomers believe that a supermassive black hole lies at the center of the Milky Way galaxy?
Astronomers believe a supermassive black hole lies at the center of the Milky Way galaxy because of the high speeds of stars and gas near the center, as well as the intense radiation emitted from that region. These observations suggest the presence of a massive object that can only be explained by a supermassive black hole.
What force pulls all objects toward the center of the earth?
Gravity is the force that pulls all objects toward the center of the Earth. This force is caused by the mass of the Earth creating a gravitational field that attracts objects towards the center of the planet.
What do objects do as a result of gravity?
Objects are pulled towards the center of the Earth due to gravity.
Why do objects fall towards the center of the earth because of what?
Objects fall towards the center of the Earth due to the force of gravity. Gravity is an attractive force between all objects with mass, pulling them towards each other. The Earth's mass creates a gravitational pull that causes objects to accelerate towards its center.
Do all objects fall toward the center of the earth?
All objects on earth are pulled towards the center of the earth by gravity. The objects are pulled to the core(center of earth), but are not pulled through because of the normal force.
What is infrared oven for baking?
Most ovens bake stuff using two distinct physical phenomena simultaneously: Infrared radiation and convection. both originate from the red hot heating coils/element. In the Infrared oven (Such as some very cheap versions of toaster ovens) there's only one or two infrared sources. these heat using radiation, but there is comparatively much less convection- based heating
Where does the energy emitted by AGN and quasars most likely originate?
The energy emitted by AGN and quasars most likely originates from the supermassive black hole at their center. As matter falls into the black hole, it releases energy in the form of radiation and powerful jets of particles, creating the intense emission observed from these objects.
What are the infrared light used for?
Infrared light has a large range of applications, and is often utilized where visible light cannot be detected, or something is blocking visible light but does not block infrared light. For example, when looking toward the center of the Milky Way large amounts of dust obscure the visible light that emanates from the center of the galaxy. This dust though does not obscure infrared light at certain wavelengths, and so astronomers can use cameras that are sensitive to this infrared light to obtain a picture of this region of space. Infrared light is also used in thermal imaging systems, and night-vision instruments are often sensitive to the infrared wavelengths that are emitted by warm objects.
How does a quasar work?
A quasar is believed to have a supermassive black hole at its center. The radiation is emitted outside the black hole's event horizon - from matter that is falling into the black hole.
Does science have a method or instrument for detecting black holes?
Black holes are distant objects found usually in the center of galaxies; therefore they are studied by astronomers, using telescopes, just as all astronomical objects are studied. Of course, black holes are studied indirectly. They do not emit radiation (or not enough radiation to view; there is Hawking radiation) but they have a strong effect on other nearby objects, which can be observed.
How does the energy created in a star change as it moves through the layers of a star?
The mass that changed to energy when fusing hydrogen-1 to helium-4 is released as photons of radiation that is absorbed and re-emitted by atoms. It takes 1 million years for the radiation in the center of the sun to reach earth.
What is the power source of a quasar?
The power source of a quasar is a supermassive black hole at the center of a galaxy. As material falls into the black hole, it forms an accretion disk that releases immense amounts of energy, generating the intense radiation emitted by quasars.

Does earths gravity pulls objects toward its center?
Yes, Earth's gravity pulls objects towards its center. The force of gravity between Earth and objects on or near its surface causes everything to be pulled towards the center of the planet.
What force pulls all objects toward the center of the earth?
Gravity is the force that pulls all objects toward the center of the Earth. This force is caused by the mass of the Earth creating a gravitational field that attracts objects towards the center of the planet.
Do all objects fall towards the center of the earth?
Yes, all objects on or near Earth's surface fall towards the center of the Earth due to the force of gravity acting upon them. This is why objects dropped from a height fall downwards.
