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.
Many people today have long been told that this is the definite, ... their calculation implied that a collision between the Milky Way and Andromeda would occur in about 50 percent of scenarios. In ...
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.

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.

According to Stephen Hawking, the human race is in danger of being wiped out in the next 100 years, and it's all our own fault. According to the BBC, the physicist says he believes humanity will ...
The Tibetan Plateau has more snow and ice than anywhere on Earth except the north and south poles, experts said.
Lotz's team tried to account for a broad range of merger possibilities, from a pair of galaxies with equal masses joining to an interaction between a giant galaxy and a tiny one. The team also analyzed different orbits for the galaxies, possible collision impacts, and how galaxies were oriented to each other.
