I Need the explanation of "The image of formation of black hole"
Please Explain Me This
Please Explain Me This
The vertical dimension represents time, the horizontal dimension space. If you take a horizontal cross-section of the diagram it shows the position of the surface of the star and of the event horizon at a given time--you can see that the radius of the star steadily shrinks and the radius of the event horizon grows from the point in space and time labeled "O", until the event horizon reaches a fixed radius at the moment the collapsing star is fully inside it. The representation of the singularity as a wavy line is just a visual convention, don't take it literally.Huma waseem said:Sir that is my basic problem.I ve got this image and now i am unable to understand it,Event horizin is considered as the radius of the black hole this is the point i got from the wekipedia site and in this image it is quite difficult to understand where is the collapsing star from where it is looking like the symmetric collapse?and the most confusing thing present here is the representation of the singularity as a wave form... the co ordinates also hav nt shown here, Can u help me find out its complete discription?
A black hole is formed when a massive star dies and its core collapses due to its own gravity. As the core collapses, it becomes infinitely dense, creating a singularity, which is the center of the black hole. The gravitational pull of the singularity is so strong that even light cannot escape, making it appear as a black hole.
Any matter that enters a black hole is pulled towards the singularity, where it becomes infinitely dense. This process is known as spaghettification, where the object is stretched and torn apart due to the intense gravitational forces. Once it crosses the event horizon (the point of no return), it is impossible for anything, including light, to escape the black hole.
No, black holes cannot be seen directly as they do not emit any light. However, we can observe the effects of black holes on their surroundings, such as the distortion of light and the movement of matter around them. These observations can help us identify the presence of a black hole.
Scientists have observed the effects of black holes on their surroundings, such as the gravitational lensing of light and the movement of stars around a central point. Additionally, the gravitational waves detected by the LIGO experiment in 2015 provided further evidence for the existence of black holes.
No, nothing can escape from a black hole once it crosses the event horizon. This is because the gravitational pull of the singularity is so strong that even light cannot escape, making it impossible for any form of matter or energy to escape as well.
