Conflict between Milky and Andromeda Way: New study reduces fusion probability
Scientists have discovered that in the next 5 billion years, only galaxies will be IDE.
An example of Adromeda and Milky Way in confrontation

A. Milky Way And your neighboring galaxy, AndromedaThey are approaching, and believe that the final result is a confrontation, but the new calculations have reduced this probability to 2% in the next 5 billion years.
This way, they have map Future, in the upcoming 10 billion yearsMilky Way and Andromeda, at present, is currently at rising at speeds of up to 100 km / h.
This study conducted by researchers of Helsinsquia, Durham (United Kingdom) and Tulouce (France) universities, in any case, It is very difficult to make an accurate indication.
A. The great cloud of Magalhis
The new data embedded in simulations has an impact on the milky of the great cloud of Magalhis (satellite galaxy of the Milky Way).
Although the mass of the Magalhes’s large cloud is only 15% of the Milky Way, Its gravity, directed perpendicular to its orbit with Andromeda, disrupts the movement of our galaxy Sufficient to significantly reduce the possibility of fusion.
Galaxies IDE 2% hypotheses
This scenario is contrary to previous beliefs, indicating that the conflict during that period is a certainty.
More than half of the imitation scenes, the Milky and Andromeda route eventually will eventually be at least close to the meeting before the IDE loses enough orbit, but in 8 to 10 billion years, not five.
In this time scale, the sun has already been removed.
Scientists are approximately estimated Million million years old, the sun is very hotThe presence of liquid water makes impossible. And, in eight billion years, Oh The sun becomes a red giantSwallowing the earth in this process.
Other simulations of the evolution of galaxies
In most other simulated cases, the two galaxies are far from a long distance, which has been actually developing without disturbance.
New innovations do not indicate an error in previous calculations, but the team has achieved Include more variables in your simulations Thanks to the modern data of the territorial telescopes, Sawala explained to Savala of the study of the University of Helsinichia.
Like previous researchers they tried to get out of the same premises, they got the same results.
“We now know that there is a very good hypothesis that can prevent the fate of the galaxies”, from Durham University, Carlos French has been added.
He is surprised that they can imitate when the researcher, see the results of the team’s calculations “With such accuracy, the evolution of gorgeous stellar groups for millions of years and decides their final destination.”
For french, it is “In combination with the power of Great Super computers. Proof of physical force.”
