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.
The Milky Way galaxy will never reach the "Great Atttractor".
FAR FAR too long
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
About 100,000 years
our galaxy is called the Milky way. its approximately 100,000 light-years (9.5×1017 km) in diameter.
No. We can't take a picture of the whole Milky Way from inside the middle of it. We would need to somehow get a camera outside of the galaxy to take that picture.
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.
The Milky Way galaxy will not melt or dissolve; it will continue to exist for billions of years. However, the Milky Way is on a collision course with the Andromeda galaxy, and they are expected to merge in about 4 billion years.
