Strange star wigs may convey the presence of worm holes if these fabulous space-time tunnels do exist, a new study shows.
The worms are from science fiction brackets; over the years, many stories, books, and films have sent their main characters zipping through widely separated locales through these cosmic shortcuts. Worm holes are possible according to Einstein's general theory of relativity but no one has ever noticed one.
The new study provides a possible way to make the first tentative discovery: Look for the light but strange movements of the stars.

"If you have two stars, one on each side of the worm hole, the star from our side you have to feel the gravitational influence of the star, which is on the other side, "said co-author Dejan Stojkovic, a cosmologist and professor of physics at Buffalo University in New York, said in a statement ," The gravitational flux will go through the hole. "
Red holes require extremely distorting It is space and time, which in turn depends on many powerful gravitational forces. So, a good place to hunt these theoretical tunnels is near the supermassive black holes that lurk in the nuclei of galaxies ̵
"So if you are mapping the expected orbit of a star around Sagittarius A *, you should see deviations from that orbit if there is a worm in a starred hole on the other side," he said.
Current surveillance techniques probably do not are sensitive enough to make such a discovery right now, he added, but that may be possible in the next decade or two with advances in the toolbox, as well as long-term monitoring of appropriate target stars, such as the S2, which orbits near Sagittarius A *
Don't worry too much much, however; such a finding, if astronomers ever manage to make one, is unlikely to have sunk.
"When we reach the accuracy required in our observations, we may be able to say that the worm hole is the most likely explanation, if you find disturbance in the orbit of S2, "said Stojkovic." But we cannot say that "Yes, this is definitely a worm." There may be some other explanation, something else on our part that is disturbing the movement of this star. "
And there is some other bad news from space exploration: the journey of worm holes will probably remain just one science-fiction dream for a very long time, if not forever," Stojkovic said.
"Even if a wormhole is passable, humans and spacecraft will probably not go through it," he said. "In reality, you will need a source of negative energy to keep the wormhole open, and we don't know how to do it. To create a huge worm hole that is stable, you need some magic. "
