The scientist has told, what future waits for the solar system after the death of man
 

The Forbes publication published an article by the astrophysicist Ethan Siegel, in which the scientist predicts how the sky will see the inhabitants of the Milky Way ten billion years after mankind perishes from the Big Bang. Sigel notes that the sky will be very different from the current one.



According to the scientist, there will be more red giants, and the Milky Way galaxy will take the form of an elliptical halo instead of a disk. In addition, in space there will be less dust and gas and fewer areas with star formations. The main reason for this outcome is that the astrophysicist calls the merger of the Milky Way with the Andromeda galaxy, which will occur in about four to seven billion years, as well as with other nearby galaxies.
However, if new intelligent beings appear in the new galaxy, they will not be able to see anything outside the star cluster, even with the help of telescopes, since galaxies from other systems will keep farther from ours.

The specialist believes that in the future universe there will be less gas and dust, but more - old stars (located below the main sequence in the Hertzsprung-Russell diagram). In the world there will be much less noticeable areas of active star formation, and within the Galaxy (at that time - the combined system of the Milky Way and the Andromeda Nebula), the stars will be located mainly within a large elliptical halo, rather than a disk.

Siegel also hypothesizes that reasonable inhabitants of our galaxy will be asked already other questions concerning the cosmos. They will have no evidence that the universe is expanding, since remote galaxies will be invisible, and there will be no idea of ​​the Big Bang.
