A scientist from University of North Carolina states she has mathematical proof that black holes (illustrated) can't exist. She said it is impossible for stars to collapse and form a singularity. Previously, scientists thought stars larger than the sun collapsed under their own gravity and formed black holes as they died.
The research was conducted by
Professor Laura Mersini-Houghton from the University of North Carolina at
Chapel Hill in the College of Arts and Scientists.
Scientist claims she has mathematical proof black holes cannot exist
- She said it is impossible for stars to collapse and form a singularity
- Professor Laura Mersini-Houghton said she is still in 'shock' from the find
- Previously, scientists thought stars much larger than the sun collapsed under their own gravity and formed black holes when they died
- During this process they release a type of radiation called Hawking radiation
- But new research claims the star would lose too much mass and wouldn't be able to form a black hole
- If true, the theory that the universe began as a singularity, followed by the Big Bang, could also be wrong.
When
a huge star many times the mass of the sun comes to the end of its life it
collapses in on itself and forms a singularity - creating a black hole where
gravity is so strong that not even light itself can escape.
At least, that’s what we thought.
A scientist has sensationally said that it is impossible for black holes to exist - and she even has mathematical proof to back up her claims.
If true, her research could force physicists to scrap their theories of how the universe began.
She claims that as a star dies, it releases a type of radiation known as Hawking radiation - predicted by Professor Stephen Hawking.
However
in this process, Professor Mersini-Houghton believes the star also sheds mass,
so much so that it no longer has the density to become a black hole.
Before the black hole can form, she said, the dying star swells and explodes.
The singularity as predicted never forms, and neither does the event horizon - the boundary of the black hole where not even light can escape.
‘I’m still not over the shock,’ said Professor Mersini-Houghton.
‘We’ve
been studying this problem for a more than 50 years and this solution gives us
a lot to think about.’
Experimental evidence may one day provide physical proof as to whether or not black holes exist in the universe.
But for now, Mersini-Houghton says the mathematics are conclusive.
What’s more, the research could apparently even call into question the veracity of the Big Bang theory.
Most physicists think the universe originated from a singularity that began expanding with the Big Bang about 13.8 billion years ago.
If it is impossible for singularities to exist, however, as partially predicted by Professor Mersini-Houghton, then that theory would also be brought into question.
One of the reasons black holes are so bizarre is that they pit two fundamental theories of the universe against each other.
Namely, Einstein’s theory of gravity predicts the formation of black holes. But a fundamental law of quantum theory states that no information from the universe can ever disappear.
Efforts to combine these two theories proved problematic, and has become known as the black hole information paradox - how can matter permanently disappear in a black hole as predicted?
Professor Mersini-Houghton’s new theory does manage to mathematically combine the two fundamental theories, but with unwanted effects for people expecting black holes to exist.
‘Physicists have been trying to merge these two theories - Einstein’s theory of gravity and quantum mechanics - for decades, but this scenario brings these two theories together, into harmony,’ said Professor Mersini-Houghton.
‘And that’s a big deal.’
