It seems you are referring not to any collapsed star, but a black hole. The "event horizon" is the area from which nothing can escape.
That refers specifically to black holes (there are other types of "collapsed stars"). This sphere is called the "event horizon".
The name for the sun's sphere of light is called the photosphere. It is the visible surface of the sun that emits light and heat.
No, the lithosphere is the rigid outer part of the Earth, consisting of the crust and the uppermost mantle. The sphere of light around the Earth is called the atmosphere, which is the layer of gases that surrounds the planet.
Only around a black hole. There is a sphere around every black hole where light orbits the black hole.
Spheres are cool. Spheres are the beauty of this galaxy.
The only thing in our solar system that gives off light of its own is the sun.
No you can't. I've allready cleared the game and there is no light sphere.
The effect of varying the intensity of light on a sphere's surface is that it will change the brightness and shadow patterns on the sphere. Higher light intensity will result in a brighter appearance and sharper shadows, while lower light intensity will make the sphere appear dimmer with softer shadows.
A black hole's photon sphere is the region around the black hole where photons can orbit in a stable circular path. The event horizon is the boundary beyond which nothing, not even light, can escape the gravitational pull of the black hole. In simpler terms, the photon sphere is where light can circle the black hole before falling in, while the event horizon marks the point of no return.
A black hole.
The photosphere.
The moon is a sphere that does not give off light of it's own. Rather, moonlight is caused by the sun's reflection off the moon.
