'Hungry' can cause time to stop

It is possible that time does not change in black holes in the final stages of life, astronomers insist.

Black holes are one of the strangest things in the vast universe . They appear when matter is compressed in an extremely small space, making the material density super large. Like hungry demons, black holes suck all kinds of matter, including light , through their tremendous gravitational pull.

The results of many studies show that the number of black holes in the universe is quite large, but so far the scientific world has not understood the activities and processes taking place within them. People often apply relativity to understand the laws of the universe, but they become meaningless to black holes.

' The rules of black holes lie beyond the physical knowledge that people know. To understand what happens inside a black hole, we have to create a new physical foundation , 'Juan Antonio Valiente Kroon, a mathematician at the University of London, told Space.

Fortunately, when black holes reach the final stages of life, the physical processes within them become much simpler.Space said, Valiente Kroon and Thomas Backdam, a colleague at the University of London, rely on relativity to create equations that can help them see what happens in the end of the black hole.

The two scientists believe that, when the time comes, everything in the black hole does not change, meaning that time does not drift.

' Someone might say that once a black hole goes into an aging stage, there is no process in them, ' said Valiente Kroon.

Astronomers think most galaxies, including the Milky Way, have black holes in the center. Some researchers speculate that every black hole in the middle of the galaxy is in the final stages of development.
