A black hole in the center of our galaxy can be a wormhole
Of all the astounding cosmic phenomena, black holes and wormholes (mole holes) attract the most attention. Perhaps this is because they are too far from the natural world as we know it. But despite all the theories related to these objects, they are full of mysteries.
In the center of the Milky Way there is a very compact source, emitting a huge amount of radio waves. Scientists say that this strange phenomenon was the result of the actions of a supermassive black hole, manifested in the central region of our galaxy. For many years of painstaking observation of outbreaks, astronomers have concluded that the object Sagittarius A * is a black hole with a mass of more than 4 million suns. Moreover, almost all if not all galaxies have black holes in the center. And we still have little understanding of how they grow and develop - that is, with such a disproportionately high speed.
Take Sagittarius A *, for example. It concentrates a mass of more than 4 million suns, but still it is a small pea compared to the giant ultramassive black holes, the mass of which can reach a billion suns. Some of them are so large that it is impossible even to determine the upper limit of the size of black holes. It is quite natural to assume that the development of such black holes takes time. But no, it seems that black holes grow literally “per day” in cosmic equivalent. Bring the size of individual supermassive black holes in line with the model of galactic evolution, scientists could only with an unknown variable, which determines their growth.
Not so long ago, two researchers - Zhilong Li and Cosimo Bambi (both from Fudan University in Shanghai) - published a paper in which they assume that Sagittarius A * is not a black hole, but a wormhole. Why is that?
Wormholes themselves are overgrown with many myths. Some people think that they serve as portals in time, others just know that wormholes can theoretically shorten the path between two remote points in space. Lee and Bambi work with an ordinary wormhole, which resembles a traditional black hole in its structure.
We quote scientists:
“Despite the exotic nature, at least several types of primary wormholes can become viable candidates for explaining the presence of supermassive objects in the centers of galaxies. These objects do not have a solid surface, so they can mimic the presence of the event horizon. They were born in a young universe and grew up during inflation, so they can explain their presence even with a very large redshift. ”
“Very large redshift” refers to galaxies that have a large redshift due to the Doppler effect. Such galaxies are very old and distant, probably formed in the first epochs after the Big Bang. The expansion of the universe shifted them far from the line of sight, so their frequency shifted to the red segment of the electromagnetic spectrum. The same effect, only in the opposite part of the spectrum, we used to determine the approach of the Andromeda galaxy to the Milky Way galaxy. The light of distant galaxies passed billions of light years before reaching Earth. But since the speed of light travel is limited, we see these old galaxies at the very beginning of their life. We also know that in the first galaxies formed after the Big Bang, black holes also nest in the central parts.
And here the wormhole alternative comes into play. The type of wormholes with the properties of black holes could be created only in one case: in the process of the Big Bang, and each of them was born simultaneously.
In fact, the type of wormhole that can imitate the properties of a black hole could be formed only during the Big Bang, and each of them had a mass of millions of suns, which might explain why the very first galaxies have supermassive black holes in their nuclei. It's just not black holes. These are wormholes whose properties are very similar to black holes.How to check it?
Scientists believe that the truth lies in the "fingerprint" of a stellar object, which we will be able to see with the release of a new instrument that will be integrated into one of the most powerful telescopes in the world. Scientists have invented an ingenious way to test their hypothesis: consider the unique glow of any such wormhole, especially Sagittarius A *.
More specifically, black holes and wormholes emit spectrally different “drops” of plasma, which can be easily determined by GRAVITY: the aforementioned tool that will soon be installed on the Very Large Telescope. Not only will the signatures be different, but the radiation rays from the two objects will differ in size. Our hypothetical wormholes will have a “very narrow radiation line,” while the black hole spectrum will be “broad and distorting the effects of special and general relativism.”
It goes without saying that GRAVITY still needs to stand up. But perhaps we will find the first proof of the existence of wormholes.
