Dark matter remains one of the greatest mysteries of physics. Scientists know that the mysterious substance constitutes the majority of all materials in the universe, far exceeding the number of natural materials such as stars, planets and humans. But no one knows exactly what it is.

"data-reactid =" 24 "> A group of astronomers has at least They have simply dismissed a hypothesis about the nature of dark matter advanced by the late Stephen Hawking, who stated that dark matter might consist of tiny black holes created at the beginning of the universe.

Astronomers and physicists are familiar with the regular black holes, which are created when a giant star explodes and the remaining core is so massive that it collapses under its own gravity. Hawking proposed a different type of black hole and a lot smaller.

According to Hawking's hypothesis, black holes could have formed in the early stages of the universe long before the formation of the first stars. At that time, all the material was free-floating gas clouds, and some of this gas could have collected and collapsed into very small black holes. Because they did not form stars, they could weigh less than a milligram.

If enough of these tiny black holes formed in the early years of the universe, they could possibly explain most or all of the undetected dark matter. Black holes are almost impossible to see directly, which would explain why dark matter has remained so inaccessible for so long.

For seven hours, astronomers looked at Andromeda and hoped to capture the flicker of revealing light from a miniature black hole. If Hawking's hypothesis was right, you would expect to see about a thousand of these twinkles. They saw one.
