That depends on where you're starting from and how fast you're going.
25,000 years.
Traveling to another galaxy at the speed of light would take an incredibly long time. The closest galaxy to us, the Andromeda galaxy, is about 2.5 million light-years away. This means it would take 2.5 million years to reach Andromeda at the speed of light.
The Milky Way galaxy will never reach the "Great Atttractor".
Traveling at the speed of light, it would take approximately 2.5 million years to reach the Andromeda galaxy, which is about 2.5 million light-years away from Earth. With current technology, it would take tens of thousands of years to reach Andromeda using conventional spacecraft.
The Andromeda Galaxy is approximately 2.537 million light-years away from Earth. Since radio signals travel at the speed of light, it would take about 2.537 million years for a radio signal to reach Andromeda. Thus, any message sent from Earth would take that long to arrive. Conversely, if a signal were sent from Andromeda, it would take the same amount of time to reach us.
The light from our Sun will take about 2.5 million years to reach the Andromeda Galaxy.
The Milky Way galaxy is about 100,000 light-years in diameter. Traveling at the speed of light, it would take 100,000 years to reach the edge. However, with current spacecraft technology, which travels at approximately 17,500 miles per hour, it would take over 20 billion years to traverse the galaxy. Thus, reaching the ends of the Milky Way is far beyond human capabilities with existing technology.
It takes around 2.5 million years for light from the Sun to reach the Andromeda galaxy, which is approximately 2.537 million light-years away from Earth.
im not sure about galaxy, but for light to reach our Earth from the sun it takes about 8 minutes
Traveling at the speed of light, it would take about 2.5 million years to reach the Andromeda galaxy, which is approximately 2.537 million light-years away from Earth. However, current technology is far from achieving such speeds, making intergalactic travel to Andromeda currently impossible for humans.
The Andromeda Galaxy is 12,904,531,200,000,000,000 miles away and the space shuttle orbits at 18,000 mph so to travel to the Andromeda Galaxy in the space shuttle would take 81.8 billion years which is around 18 times the currrent age of the universe!!!
The time it takes for a cluster galaxy to form would be 13.99 BILLION years....
