It depends on your speed.

The distance of Andromeda galaxy from Earth is 2.537 million light years and hence it will take that many years for light to travel to Andromeda galaxy.

However, to leave planet Earth, an escape velocity of 11.2 km/s or 40,320 km/h is required and a speed of 42.1 km/s is required to escape 's gravity and exit the Solar System). As these are very small fraction of velocity of light, the time taken will be much much more than billions of years.

How do us humans know that there are millions of other galaxies? If galaxies are millions of years apart, how do scientists know that there are billions of other galaxies and that andromeda is the closest?

There are a ton of extremely powerful telescopes both here on Earth and in space that is capable of looking billions of light years far. And we can see a...

Edwin Hubble discovered the universe was expanding by measuring the light of distant stars, and by showing that those distant stars were moving further away from the earth. If this is so, then why is the Andromeda Galaxy moving closer to us?

Andromeda is being pulled apart by the expanding universe. But the gravity between the Milky Way and Andromeda is strong enough to overcome this expansive force. Gravity is pretty...

If the nearest star to us went supernova what effect would it have on earth, how long would it take to reach us?

If a supernova occurs between about 30 and 1000 light years away it would have significant effects on 's biosphere. The nearest star is just over 4 light years away...

When we look at a picture of a galaxy, how is it possible that we see a disk form or a near perfect circle? Considering how long light takes to travel between the galaxy and the earth, shouldn't the images be more distorted?

This is because our atmosphere distorts the light coming from the cosmos. Telescopes in space can take much more clearer pictures and that's how the perfect circle of galaxies are...

What is the possibility that there is life in the galaxy Andromeda?

The Andromeda Galaxy is massive (bigger than our Milky Way) so that makes it having many more stars than the Milky Way, which makes a higher chance of having stars...

Are there planets in the Andromeda Galaxy? If so how many? Could life be sustainable there?

At this distance we can not resolve planets.Even resolving individual stars is difficult >So astronomers do not have any idea of the planets in Andromeda galaxy..

Half-life of carbon-14 is 5730 years. A piece of wood that contained 0.200g of Carbon-14 when it was alive now contains 0.0125g of Carbon-14. How old is the piece of wood? 5730 years old 11460 years old 17190 years old 22920 years old?

$(1/2)^(t/5730)(I)=A$ I = initial amount, A = current amount, t = years I=0.200g, A= 0.0125g, solve for t $(1/2)^(t/5730)(0.200)=0.0125$ $(1/2)^(t/5730)=0.625$ $log_(1/2)((1/2)^(t/5730))=log_(1/2)0.0625$ $t/5730=4$ $t=22920$
