Simple answer no if the Milky Way did not exist there would be no human race.
We are part of the Milky Way galaxy in the most fundamental ways. We live here. We evolved here. Every element that goes up to make the Earth and you except hydrogen and most of the helium comes from stars that lived and died billions of years ago within the Milky Way. We owe our entire existence to the Milky Way.
It is absolutely probable that life has arisen in far off galaxies. They might even look remarkably like humans although that is very doubtful but still they will not be humans.
It's doubtful if a civilization could still exist within an elliptical galaxy due to the age of the stars. If they could, then the sky would have a slight red tinge, nothing like the Milky Way.
The diameter of the Milky Way galaxy is about 100,000 light-years. If the Sun and Earth were at the edge of the disk, we would still be within the galaxy's boundaries, so the diameter would remain around 100,000 light-years.
That would be a galaxy. Our solar system is part of the Milky Way galaxy, which contains billions of stars, planets, and other celestial objects.
If you were to get close to the Milky Way galaxy, you would continue to see more stars and gas clouds as you approach it. Ultimately, you would not be in any danger as the Milky Way is a collection of stars, gas, and dust held together by gravity.
The Milky Way galaxy is approximately 100,000 light-years in diameter. One light-year is equivalent to about 63,240 astronomical units (AU), so the distance across the Milky Way galaxy would be around 6.32 million AU.
It's doubtful if a civilization could still exist within an elliptical galaxy due to the age of the stars. If they could, then the sky would have a slight red tinge, nothing like the Milky Way.
That would be the Milky Way Galaxy.
A spiral galaxy
I believe that would be M31.
We are in the Milky Way galaxy.
It's very easy to reach one galaxy ... the "Milky Way" ... because we are in it.No human can reach any other galaxy, because the trip would last longer thanhumans live.
its a spiral galaxy and the earth is so far the only planet in the milky way where we know we can live
The diameter of the Milky Way galaxy is about 100,000 light-years. If the Sun and Earth were at the edge of the disk, we would still be within the galaxy's boundaries, so the diameter would remain around 100,000 light-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.
In Kannada, we would say:Haalina Marghada Taaragana
The Canis Major Dwarf Galaxy is currently considered to be the closest galaxy to the Milky Way. It is 25,000 light years from our solar system and 42,000 light years from the center of the Milky Way. Its status as a galaxy is still disputed in some scientific circles. If the Canis Major Dwarf Galaxy loses its galaxy status, then the Sagittarius Dwarf Spheroidal Galaxy would reacquire the title as the Milky Way's closest neighbor. It is it is roughly 50,000 light years from the center of the Milky Way.
No scale was specified. However, if the Earth was one inch, the Andromeda Galaxy would be 29,300,000,000 miles away.
