Taking the milky-way galaxy to be approx 100 000 ly across, and travelling at a realistic speed of 5 000 km/h, it would take just under 200 000 billion earth years to traverse the galaxy end to end.

Andromeda is unquestionably purely 2.5 MILLION easy years, from the Milky way, no longer 5 billion. The collision between the Andromeda and Milky way is 5 billion years away in time; the collision won't ensue for yet another 5 billion years... perhaps that's what's confusing you. this is coming near us through that factor talked approximately as gravity. that's in all likelihood no longer coming near us in a suited directly line the two, yet possibly in a curved course. "i dont comprehend the reason to why directly at us milkyway while there is a lot empty area throughout?" 2.5 million easy years is an extremely very minuscule distance while in comparison with the dimensions of the universe. the gap has no longer something to do with the potential for the collision, the cost and trajectories do. "If andromeda galaxy is attatch to the milkyway.. how could that be so occurring while 5 billion years for the time of is so some distance to ever have a galaxy atracting yet another galaxy from that distance?" it is not "related" to the Milky way and that they don't seem to be that some distance from one yet another. we are speaking approximately huge galaxies hundreds of thousands of cases larger than the solar and separated by way of a distance of purely 2.5 million easy years (gravity is going to effect them significantly by way of the years). The Milky way is a hundred,000 easy years for the time of and we are able to work out out into area very nearly thirteen billion easy years, 2.5 million easy years isn't something. "Its in contrast to each of the galaxys u see around us additionally are going to be attatck by way of incomming galaxys additionally." Andromeda and the Milky way are the two best galaxies contained locally crew, a galaxy cluster that contains Andromeda, the Milky way, Triangulum and incredibly some smaller galaxies. there are a number of galactic communities, yet they are separated by way of 1000's of hundreds of thousands or billions of light years and function little effect on one yet another.

from end to end it could take 100000 light years
from up to down 25000 light years
the milkyway galaxy is like a disk

It takes light about 100,000 years to get across the Milky Way.

It's about 100,000 light years across. We're about 30,000 light years from the center, so it would take us 70,000 years at near light speed to get to the far edge.

The Milky Way has been calculated to be over 25,000 light-years across. Assuming you could travel at the speed of light, it would take 25,000 years to traverse it.

By what means of travel? I am able to teleport instantaneously by the intent. Your choices of movement may take longer.

Well that would really depend on how fast you were going.
