Earlier this Professor Stephen shocked physicists by saying ‘there are no black holes’.

In a paper published online, Professor Hawking instead argues there are ‘grey holes’
‘The absence of event horizons means that there are no black holes – in the of regimes from which can’t escape to infinity,’ he says in the paper, called Information Preservation and Weather Forecasting For Black Holes.
He says that the idea of an event horizon, from which light cannot escape, is flawed.
He suggests that instead light rays to rush away from the black hole’s core will be held as though on a treadmill and that they can slowly shrink by spewing out .  
One of the black holes are so bizarre is that they pit two fundamental theories of the universe against each other.
Namely, Einstein’s theory of 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 these two theories proved problematic, and has become known as the black hole information paradox – how can 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.’
