Forget the murderer asteroids and nuclear annihilation: The final destination of the Earth can affect a cosmic currency launch.
Astronomers have revealed that our Milky Way galaxy has a 50/50 possibility of colliding with its massive neighbor, the Andromeda galaxy, at some point in the next 10 billion years, an intergalactic combination that could launch our solar system into a deep space or whole swallow land.
Cuise sci-fi panic or not.
“It used to appear to merge with Andromeda to form a colossal ‘Milkomeda’, said Professor Alis Deason, a computational cosmologist at Durham University, by The Daily Mail.
“Now, there is a possibility that we can avoid this destination completely.”
In other words: the end of the world may not be as Inevitable as we thought, at least not the galaxy next door.
The new study, published in “Nature Astronomy”, analyzed 100,000 simulations of the future of the Milky Way.
The findings, thanks to the refined data of the Hubble Space Telescope of NASA and the Gaia mission of the European Space Agency, dramatically reduced the previous predictions of a guaranteed galactic accumulation by only 5 billion years.
“Ultimately, the probability went from certaintage to a currency,” Dr. Till Sawala, from Helsinki University, to Space.com.
The finding factor of the gravity of neighboring galaxies, especially the great Magellan cloud, a much smaller satellite galaxy, whose shot may be in the dairy way.
“The main difference between our research and previous studies is that we benefited from newer and more precise data and that we considered a more complete system,” Sawala said to the site.
Although a 220,000 km / h galaxy collision sounds catastrophic, astronomers say that an impact of head is “very unlikely”.
In fact, only 2% of the simulations showed a direct success in 5 billion years. Most of the scenarios had the galaxies turned to each other, possibly merging much later, or at all.
Still, if they do Harvested, it could be a literal stars program.
“We see that external galaxies often collide and merge with other galaxies, sometimes producing the equivalent of fireworks,” said Durham’s cosmologist professor Carlos Frenk through the Daily Mail.
“Until now, we thought that this was the fate that our Galaxy of the Milky Way expected. Now we know that there is a very good chance that we would avoid this frightening destination.”
But even if the Earth comes from this stellar Shakedown, don’t feel too comfortable.
As reported earlier, it is expected that our Sun becoming a swollen red giant in about 5 billion years, probably boiling the Earth’s oceans or swallowing the planet completely.
So, yes. Choose your apocalypse.
“If [the Milky Way-Andromeda collision] It happens, it can take place after the Earth and the Sun no longer exist, “Sawala told Daily Mail.
“Even if it happens before, it is very unlikely that something happens on Earth in this case.”
Translation: When the universe is achieved to break the Milky Way, we will probably be toast.
However, some experts say that galactic fate is more than an obsession with an astronomer.
“The fate of our Milky Way’s galaxy is a broad interest, not only for astronomers,” said Associated Press in Raja Guhathakurta at the University of California, Santa Cruz.
And while the galaxy could hardly survive, maybe not.
According to Sawala, “Of course, there is also a very significant possibility for humanity to end much earlier, without the need for astrophysical help.”
