Is it possible to travel a light-year? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. According to Albert Einstein’s theory of special relativity, summarized by the famous equation E=mc2, the...
How far away is 1 light-year in km? A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km). How long does it take to walk 1 light-year? Walking? That would...
How long would it take to travel 1 Lightyear? Light-year is the distance light travels in one year. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year. How long...
How long would it take to reach Andromeda at the speed of light? Although it may be one of the closest galaxies to our own, since the Andromeda Galaxy is 2.5 million light years distant it would take 2.5 million years...
How long would it take to get to the Andromeda Galaxy from Earth? Although it may be one of the closest galaxies to our own, since the Andromeda Galaxy is 2.5 million light years distant it would take 2.5 million years...
How long will it take to reach the Andromeda galaxy at light speed? Although it may be one of the closest galaxies to our own, since the Andromeda Galaxy is 2.5 million light years distant it would take 2.5 million years...
How long would it take to get out of our Milky Way? Even traveling at the speed of light, it would take nearly a hundred thousand years! Is it possible to go beyond the Milky Way? The technology required to travel...
How long would it take us to get to another galaxy? The closest galaxy is the recently discovered Canis Major dwarf galaxy, which is “only” 25,000 light-years away. So it would take 25,000 years to get there if you traveled at...
How long will it take Andromeda to reach the Milky Way? Taking also into account the sun’s motion, Andromeda’s tangential or sideways velocity with respect to the Milky Way was found to be much smaller than the speed of approach (consistent...
What is the diameter of Andromeda galaxy? Is Andromeda bigger than Milky Way? Most Messier objects are star clusters or gas clouds in our Milky Way galaxy. But the Andromeda galaxy is a whole separate galaxy, even bigger than our Milky...
