A new research of two scientists from the Shanghai University suggests that it is possible that there is a wormhole in the middle of the Milky Way.
It is estimated our galaxy has a supermassive black hole called Sagittarius A* at its center, which is an object with a mass four million times that of the Sun.
An intense emission of radiation from this relatively small object, combined with the influence it has on the motion of adjacent celestial bodies, led astrophysicists to this conclusion.
Wormholes from the past
The laws of physics allow the existence of wormholes, which are ‘shortcuts’ in the structure of spacetime that connect distant points either in the same universe or even in different universes.
The hypothesis that a wormhole can exist in the center of our galaxy is not new. Its presence is associated with quantum disturbances that occurred in the early Universe and were maintained after the era of cosmic inflation, when the universe had increased by several orders of magnitude.
A wormhole in the center of the Milky Way could indeed solve a problem relating to the formation of it: many scientists consider that the formation of galaxies requires a supermassive black hole, which stabilizes the structure of the galaxy with its pull.
However, the creation of a giant black hole requires a long time, many times greater than the age of some of the galaxies we can observe. Unlike a wormhole, it owes its presence to the phenomena that prevailed immediately after the Big Bang.
Black hole or wormhole?
The question that arises then is whether one can determine whether the Sagittarius A* is a black hole or a wormhole. The answer is «yes» according to Zilong Li and Cosimo Bambi of the Shanghai University. The fact that a wormhole is much smaller than a black hole is the key point of their theory.
The two scientists argue that the superheated material which is rotated at high speed around a black hole has a different shape relative to that around a wormhole.
The scientists also calculated the difference in the emission of infrared radiation from the surrounding area and created computer simulations that could help astronomers to decide on the nature of Sagittarius A* in the coming years.
For now, this distinction is not possible, since there is no technical infrastructure for the observation of Sagittarius A* in the infrared wavelength.
But this will change soon, as the Very Large Telescope in the Atacama Desert of Chile will soon have this feature, giving answers to researchers about the past of our galaxy.
