Not long at all - as you/we are already in it. About 25,000 light years from the centre.
We are in the Milky Way galaxy.
FAR FAR too long
The Milky Way galaxy will never reach the "Great Atttractor".
FAR FAR too long
the earth is part of the milky way galaxy if that was your question.
Traveling across the Milky Way galaxy at the speed of light would take approximately 100,000 years. However, with current technology, it is impossible for humans to travel at such speeds, so the actual time to traverse the galaxy would be much longer.
No - you are already IN the Milky Way Galaxy
The Milky Way galaxy is about 100,000 light-years in diameter. Since light travels at a speed of approximately 299,792 kilometers per second, it would take a ray of light about 100,000 years to travel from the sun to the edge of the Milky Way.
our galaxy is called the Milky way. its approximately 100,000 light-years (9.5×1017 km) in diameter.
About 100,000 years
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.
Assuming you are referring to our Galaxy - The Milky Way. Light will take about 100,000 years to get from one side to the other.
