A newly developed solution to the equations at the heart of Albert Einstein's most revolutionary theory suggests hypothetical stars called "nestars" could be made from stacked gravitational stars, or "gravastars," like Russian tea dolls, also known as matryoshka dolls. One of the most impressive things about Einstein's 1915 theory of gravity,  general relativity , is just how many incredible cosmic objects its central equations have predicted . As well as predicting that gravity arises from objects of mass curving the fabric of spacetime, general relativity spawned theories of black holes and the ripples they create in that fabric called gravitational waves. Both of these things have had their existence confirmed through observation; anti-black holes called white holes, and "wormholes" that potentially linking them with black holes, are other general relativity-based ideas that have remained purely theoretical, however. Only time will tell ...

Astrophysicist Alexander Panov detected two stars where they found signs of extraterrestrial civilizations. The scientist told what kind of objects they were and why they interested specialists. The astrophysicist affirms that the modern equipment of the observatories makes it possible to find systems inhabited by extraterrestrials. He drew attention to one more fact. When something flies past a star, its mass “wobbles” slightly. But this is not always the case. It may not respond to some objects. And it is precisely this lack of reaction that signals the passage of an astroengineering structure. Its mass is too small to affect the star. Similar objects are found using the transit method. Space stations, which could theoretically be built by extraterrestrial civilizations, become noticeable during their passage through the stellar disk. In a telescope, this looks like a decrease in visibility in a given area. Recently, scientists mana...
