Stop everything. Stop it now. A new study has said that black holes could be the “back doors” to other regions of the universe.

Can humans pass through them?

Scientists have said it is unlikely anyone passing through one of the gateways would survive, so don’t get your hopes up for fleeing the Earth just yet.

First they would be “spaghettified” – stretched out like a strand of pasta – by the black hole’s immense gravity.

Once on the other side of the “door” the traveller would be compacted back to normal size, but could not count on being restored back to life.

Black holes are places where matter has been squashed to such a density by gravity that the normal laws of physics break down.

So what does the new study say?

The new theory rejects the view that at the centre of a black hole spacetime curves to an infinite point known as a “singularity” and all matter is destroyed.

Instead, it proposes that the heart of the simplest type of electrically charged, non-rotating black hole is a very small spherical surface. This acts as a “wormhole” – a doorway or tunnel through the fabric of spacetime of the kind seen in countless sci-fi stories.

Dr Gonzalo Olmo, from the University of Valencia in Spain, said: “Our theory naturally resolves several problems in the interpretation of electrically-charged black holes.

“In the first instance, we resolve the problem of the singularity, since there is a door at the centre of the black hole, the wormhole, through which space and time can continue.”

The wormhole predicted by the scientists’ equations is smaller than an atomic nucleus, but gets bigger as more electrical charge is stored in the black hole.

The new model also gets round the need for “exotic” energy or matter to create a wormhole.

According to Albert Einstein’s theory of gravity, a wormhole can only appear in the presence of matter with highly unusual properties, possessing negative energy, pressure or density. Such “exotic matter” has never been observed.

“In our theory, the wormhole appears out of ordinary matter and energy, such as an electric field,” said Dr Olmo.

The research is published in the journal Classical And Quantum Gravity.
