| The discovery of a black hole 30 billion times bigger than the Sun has put scientists in trouble |
Scientists believe that our galaxy, known as the Milky Way, contains millions of black holes, but now a group of astronomers from the UK claim to have discovered the largest black hole in the universe. has been discovered.
The size of this black hole is incredible. This can be estimated from the fact that the Sun is 109 times larger than the Earth, but the black hole discovered now is believed to be 30 billion times larger than the Sun.
Dr. James Nightingale of Durham University in the UK was the head of the research. They say they have a hard time believing how big this thing is.
How was a black hole discovered?
These scientists from Durham University discovered this black hole using a new technique. This technique is called 'Gravitational Leasing'.
In this technique, scientists measure the amount of light that a black hole absorbs. Their research was published in the journal 'Monthly Notices of the Royal Astronomical Society'.
Dr. James told the BBC: 'Even as an astronomer I find it difficult to understand how big this object is.'
"If you look at the night sky and count all the stars and planets at one point, they will all be a very small fraction of the mass of the black hole."
"This black hole is bigger than most galaxies in the universe."
He said that this discovery has challenged the understanding of astronomy. 'How can such a big black hole be formed in the 13 billion years of the universe?'
Using this new technique, Dr. James says, 'we will be able to discover more black holes and learn how they evolved.'
What is a black hole?
Black holes form near the end of a star's life. As these stars die due to their mass, they collapse from within due to their own weight and pressure.
A black hole is a region in space where matter becomes infinitely dense. The gravity is so strong here that nothing, not even light, can escape.
Black holes form at the explosive end of the life of some very massive stars. Some black holes can be billions of times larger than our Sun.
Scientists cannot say with certainty how these black holes at the center of galaxies formed, but it is clear that they provide energy and keep the galaxies moving and influence their evolution.
