Light would reach it in 2.2 million years, but according to Einstein's relativity, a spaceship can only get close to the speed of light , but never reach it. At that sort of speed, due to time dilation , a spaceship would get there almost instantly, but it would take an almost infinite amount of energy.

So a spaceship very very close to the speed of light could reach it in minutes, whereas on Earth 2.2 million years would have passed.

Not only does time slow down, but mass increases and length contracts at relativistic velocities. So as an object approaches the speed of light, its mass becomes greater and greater, until eventually it begins pushing up towards the mass of a star. The amount of energy needed to push the mass higher becomes correspondingly greater. Another effect, however, is that as you approach the speed of light, your own escape velocity increases. Before you reach the speed of light you enter your own Schwarzchild radius, effectively pinching off from the rest of the universe as a black hole. So you can't even theoretically get "infinitely close" to the speed of light. There are limiting factors precluding it.

# How long would it take to get to the Andromeda Galaxy traveling at 100000 miles per second?

100,000 miles per second = 360,000,000 miles per hour Andromeda Galaxy is 2.5 million light years away Which is 14,699,563,432,959,025,000 miles Which is 408,237,797,313

# If you could travel at 100000 times the speed of light how long would it take you to go to the other side of our Galaxy?

At the speed of light itself you would cross the galaxy in zero time. Time stands still for the subjective observer (the person or object moving) at the speed of light. What i

# Why does Andromeda galaxy give out light?

Because the stars of Andromeda emit light

# How long would it take to get to Andromeda Galaxy at 600 mph?

I hope you have a very good book. It will take ............... 2,838,945,720,000 years - almost 3 trillion years.

# How long does it take light to travel from the Sun to the Andromeda Galaxy?

The light from our Sun will take about 2.5 million years to reach the Andromeda Galaxy.

# How long would it take for a space shuttle to travel to the Andromeda galaxy?

The maximum speed achieved by the shuttle is 17,500mph The Andromeda Galaxy is about 2.54 million light years away, which is about 1.5 x 10 19 miles. This gives a total tim

# How long will it take to reach the Andromeda galaxy by space shuttle?

The Andromeda Galaxy is 12,904,531,200,000,000,000 miles away and the space shuttle orbits at 18,000 mph so to travel to the Andromeda Galaxy in the space shuttle would take 8

# How long would it take to count all stars in Andromeda galaxy?

Since it is not possible to SEE the stars in Andromeda, it would take forever. Of course, if you can wait 3 billion years until Andromeda collides with the Milky Way, it will

# How long would it take you to reach earth's nearest galaxy if you were travelling at the speed of light?

Aside from the Magellanic Clouds (small sibling galaxies to the Milky Way visible from the southern hemisphere) the closest galaxy to our own (the position of the Earth in the

# How long does it take light from the star Andromeda to reach earth?

First of all, Andromeda is not a star, it's a collection of many stars, dust, and gas, all held together by gravity in a spiral shape. In other words it's a spiral galaxy. And

# How long would it take to get to the end of your milky way galaxy at the speed of light?

The Milky Way has a diameter of about 100,000 light-years, meaning it takes 100,000 years to get across at the speed of light. We are about 30,000 km from the center, meaning

# Would you escape the inevitable collision of the Milky Way and Andromeda Galaxies in three billion years traveling at the speed of light from the earth?

Yes of course you would - assumming you sped away from Andromeda. Andromeda is approaching us at about 500,000kph, so you could cut your speed down somewhat and still esc

# How long would it take to get to center of your galaxy at the speed of light?

Objectively, about 26,000 years - but IF (and you cannot!) you could travel at the speed of light, it would seem like no time at all had passed.

# Does the speed of light allow the Andromeda Galaxy to emit a blue shift?

There is some blueshift in the Andromeda galaxy as it is movingtoward us. The speed of the Andromeda Galaxy relative to the sun isabout 300 kilometers per second or about 0.1%
