The Andromeda–Milky Way collision is a galactic collision predicted to occur in about 4.5 billion years between the two largest galaxies in the Local Group—the Milky Way (which contains the Solar System and Earth) and the Andromeda Galaxy.
For the two-body system, their calculation implied that a collision between the Milky Way and Andromeda would occur in about 50 percent of scenarios. In the three-body system with M33, that ...
Illustration of the collision path between the Milky Way and Andromeda Galaxy The Andromeda Galaxy is approaching the Milky Way at about 110 kilometres (68 miles) per second. [ 135 ] It has been measured approaching relative to the Sun at around 300 km/s (190 mi/s) [ 1 ] as the Sun orbits around the center of the galaxy at a speed of ...
Intergalactic travel for humans is therefore possible, in theory, from the point of view of the traveler. [7] For example, a rocket that accelerated at standard acceleration due to gravity toward the Andromeda Galaxy and started to decelerate halfway through the trip would arrive in about 28 years, from the frame of reference of the observer.

English: This animation depicts the collision between our Milky Way galaxy and the Andromeda galaxy. Hubble Space Telescope observations indicate that the two galaxies, pulled together by their mutual gravity, will crash together about 4 billion years from now.
In order for humans to live there, a few things would have to happen. First off, its climate is inhospitable with an average temperature of minus 80 degrees Fahrenheit.
Astronomers have estimated the Milky Way Galaxy will collide with the Andromeda Galaxy in about 4.5 billion years. Some think the two spiral galaxies will eventually merge to become an elliptical galaxy whose gravitational interactions will fling various celestial bodies outward, evicting them from the resulting elliptical galaxy.
Imagine life with no humans. One group of researchers has done exactly that -- and they even made a map to show how the world might look sans homo sapiens. SEE ALSO: California drought may ...
