Astronomers study the S2 star and other stars orbiting a black hole | FREE NEWS

What are the stars hiding around a supermassive black hole in the center of our galaxy?

Spectacular time-lapse photography with the VLT telescope of the European Southern Observatory in Chile captures stars that revolve around a supermassive black hole in the Milky Way galaxy, including S2, a star orbiting incredibly close to this space monster. Recall that the black hole Sagittarius A * is located 26 thousand light years from Earth. However, the incredible speed with which the stars rotate (4800 km/s) and the proximity of S2 to a black hole can also mean that there is a wormhole or a wormhole nearby.



As watched the stars next to the black hole

According to phys.org, S2 came incredibly close to a black hole in May 2018. Astronomers tracked this event using VLT. Observations showed that at maximum approach, the star was located at a distance of at least 20 billion km from the black hole and moved at a speed of 25 million km / h. Researchers note that S2 is an ideal test object for studying extremely strong gravitational fields and testing Einstein’s theory of general relativity. It should be noted that this is not the first time that astronomers have observed the approach of S2 to Sagittarius A *. The last time S2 approached a black hole 17 years ago. In May 2018, astronomers collected the data and made a slow motion video, as well as an animation that mimics the orbits of a close group of stars that circle around a black hole.

However, the speed and nature of the movement of stars around Stelts A * prompted researchers to think that a wormhole could be located next to a black hole. De Chiang Dai from the Center for Gravity and Cosmology at Yangzhou University and Deian Stojkovic from Buffalo University suggest that if the wormhole is really near Sagittarius A *, its mouth will be larger than the event horizon of the black hole – a point beyond the black hole from which it cannot escape nothing, not even light. This means that particles and forces can pass through a wormhole without being absorbed by a black hole.

Gravity leaks

De Chang and Stojkovic point out that the wormhole can be a two-way street for gravity, electromagnetic radiation and electric charges. Therefore, the gravity of a star or stars rotating around the other end of a wormhole must propagate through a wormhole to attract stars rotating around Sagittarius A *, and vice versa. However, the detection of the gravitational effect of this wormhole twin on S2 will require an accurate measurement of acceleration, which is currently not possible. As a result, astronomers will have to wait for the next generation of 30–40-meter telescopes, like the VLT. According to physicsworld.com, the mass of the wormhole on the other side can affect the orbits of objects on our side.

Worm whole

However, dark objects invisible to us that move near Sagittarius A *, such as neutron stars, can also perturb S2’s orbit. There are other problems with the wormhole hypothesis. In particular, the reason why the mouth of the wormhole should be constantly open and stable. This requires either negative energy, or some kind of complex setting that allows you to keep the mouth open. Note that the concept of negative energy is not hypothetical, since the mysterious dark energy responsible for accelerating the expansion of the Universe is a form of negative energy. However, it is not known whether the release of dark energy or other exotic matter with the same properties into a wormhole is possible. To date, there is no answer to the question of whether there is a wormhole in the immediate vicinity of the black hole and it will probably take several decades to wait.
