A mysterious stranger Omului may be a cosmic iceberg

looks like Omului – the mysterious visitor from other star systems.
Since in 2017 opened the asteroid Omwamwi first interstellar object discovered in the Solar system, it is the cause of endless controversy among astronomers. The fact that a huge space rock an unusual cigar-shaped, not easily classified as a comet or an asteroid. The uncertainty Omwamwi led to the spread of various theories about its origin and composition. There are suggestions that it is an alien spacecraft, the remains of a small planet, torn apart by star-master, and even that Omului – a huge space iceberg.
Interstellar guest
Two astrophysics from Yale University has put forward a new theory that the asteroid is Omwamwi qualities of the interstellar iceberg. The work traces the origin Omwamwi up to giant molecular clouds – Ghost object that is massive «star nursery», who is stretched for light years and contains enough gas for the formation of tens of thousands of stars. As shown by the results of a new study, the nurseries can push into outer space the hydrogen icebergs that look and behave very similar to Omwamwi. Preprint of the study in the journal Astrophysical Journal Letters.
As Wired, co-author Darryl Seligman from the University of Chicago believes that the «despite the fact that the hydrogen iceberg a little exotic, he explains every mysterious thing in Omwamwi». If Seligman and his colleagues are right, Omwamwi will become not only the first discovered interstellar object, but also the first hydrogen iceberg.
Hydrogen normally exists as a gas and is the substance that nourishes the process of fusion in stars like our Sun. But if he is sufficiently cool, it may solidify. The only known region of the Universe, cold enough for the phase transition, it is dense, cold, cold heart of a giant molecular cloud. It is noteworthy that the core of a giant molecular cloud has a relatively short lifespan – only a few hundred thousand years. Over time it eroded the flow of galaxies until it fades. But according to the theory of the hydrogen of the iceberg (iceberg theory hydrogen), during the brief existence of the core of frozen hydrogen molecules cling to the dust in the cloud, thereby forming a block of ice. The authors note that this is «the painfully slow process».
If Omwamwi in fact an iceberg, it explains a lot.
The Theory of the hydrogen of the iceberg could also explain the strange shape Omwamwi. Once the core of a giant molecular cloud is dissipated and the iceberg drifting in the void, it is constantly bombarded by cosmic radiation, thereby chipping pieces from the iceberg that will lead to a more elongated shape. Seligman compares Omwamwi with a piece of soap, which becomes more flat and oval as you use.
The New theory explains the reason why Omwamwi began to accelerate when I entered the Solar system. According to the theory put forward by several astronomers, Omwamwi moves through the gas. That is why the comet has a brilliant tail that consists of carbon dioxide and water. But when astronomers watched Omwamwi, we found no emissions that can explain the acceleration of the object – unless, of course, Omwamwi not thrown pure hydrogen, which is watching the object telescopes can't detect.
Omwamwi full of surprises from the first day
What is hydrogen iceberg?
The Theory of Seligman and Laughlin makes you imagine a completely new type of astrophysical object, hydrogen iceberg – which has never before been observed, and hardly even thought about its existence. Seligman believes that one of the only mention of something similar is contained in an astronomical article in the 1990-ies, in which it was assumed that solid hydrogen may explain dark matter.
As for physics, there is no reasons why hydrogen icebergs can not exist – and they seem to explain many things in relation to Omwamwi. However, extraordinary claims require extraordinary evidence, and we will never know for sure whether Omwamwi actually a block of hydrogen ice. Interstellar object hurtling out of the Solar system at a speed of 12 654 kilometers per hour, and it is impossible to observe, except for launch an interstellar mission to intercept the object. What do you think, what really is this interstellar visitor? Response
