BLACK HOLES "DOORS TO ANOTHER WORLD"

Black holes are doors to other parts of the universe. But you wouldn't ever get to come back. Anyone who managed to get through one of the mysterious doors would end up "spaghettified" and stretched out like a long strand of pasta. They'd get squished back down to size once they reached the other side, but it's unlikely they'd be alive to see it. Previously scientists have held that all matter inside of a black hole is destroyed and so there would be no way of making it through. But the new reaserch suggests that it could act as a doorway or a tunnel. Black holes are places where matter has been squashed to such a density by gravity that the normal laws of physics break down. The new theory rejects the view that at the centre of a black hole space-time 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 space-time. The wormhole is smaller than an atomic nucleus, but gets bigger as more electrical charge is stored in the black hole. The problem of the singularity is resolved since there is a door st the centre of the blackhole, the wormhole, through which space and time can continue. The new model gets around the need for "exotic" energy or matter to create a worm hole. In this theory, the wormhole appears out of ordinary matter and energy.
