At a constant acceleration of 1 g, a rocket could travel the diameter of our galaxy in about 12 years ship time, and about 113,000 years planetary time. If the last half of the trip involves deceleration at 1 g, the trip would take about 24 years. If the trip is merely to the nearest star, with deceleration the last half of the way, it would ...
For example, a spaceship could travel to a star 32 light-years away, initially accelerating at a constant 1.03g (i.e. 10.1 m/s 2) for 1.32 years (ship time), then stopping its engines and coasting for the next 17.3 years (ship time) at a constant speed, then decelerating again for 1.32 ship-years, and coming to a stop at the destination. After ...
A generation ship, generation starship or world ship, [1] is a hypothetical type of interstellar ark starship that travels at sub-light speed. Since such a ship might require hundreds to thousands of years to reach nearby stars, the original occupants of a generation ship would grow old and die, leaving their descendants to continue traveling.
The travel time is only 600 years due to the discovery of a form of faster-than-light travel that cuts down the time to traverse the 2.5 million light years between galaxies (by comparison, it is mentioned in the game that a cargo vessel, also sent in the direction of Andromeda, will not arrive for more than two million years.)

According to the authors, a black hole to be used in space travel needs to meet five criteria: [5] has a long enough lifespan to be useful, is powerful enough to accelerate itself up to a reasonable fraction of the speed of light in a reasonable amount of time, is small enough that we can access the energy to make it,
The current distance to this cosmological event horizon is about 16 billion light-years, meaning that a signal from an event happening at present would eventually be able to reach us in the future if the event was less than 16 billion light-years away, but the signal would never reach us if the event was more than 16 billion light-years away.

Scientists have discovered a mysterious pulsating light—and they don’t know what it could be. It pulses at a rate of about once every 21 minutes, and has been doing so since at least 1988.
The vessel he designed was the IXS Enterprise, named after the famed ship of the Star Trek franchise. The energy required to power the warp drive, according to White, [ 3 ] is approximately the negative (negative energy is required for the Alcubierre drive concept to function) mass–energy equivalence of Voyager 1 , which has a mass of ...
