Question

If an object isn't neccesary to heat a plasma when its fall to a black hole ...
There is a matter quasars matter ...
So in a spiral shape it move down towards horizon ...
Itz density and speed both increases ...



This much how i know ...
I just a junior still hos much at my limit i know i told u ​

Answer 1

Answer:

An object isn't necessarily heated to a plasma when it falls into a black hole. With quasars matter spirals down towards the event horizon so both it's speed and density increases, but this doesn't heat it directly. ... Also accretion disks will form around any heavy object.

Answer 2

Answer:

To understand roads and subways at new places.

To calculate distance between two places.

To know whether there are two or more paths to the same place and which is the shortest.

We can get information about mountains, rivers, valleys or any other thing, which may come on the way, and we can prepare for that.
