I get that, just like how the suns light takes 7 years to hit earth, but how is it in only 20 years we can see galaxies 40+ light years away? Doesn't make sense to me.

i don't know who is dumber, you or the person who told you that.
Whats the point even if space travel technology is getting more advanced, the government will never tell the truth about what they discover out inspace, just because they believe society and religion isn't ready to accept extra terrestrial life-forms.Originally Posted by recycledpaper
looking at all those galaxies.. you KNOW there's a place like pandora out there
the only problem is getting there... any NT'ers up to date on space travel technology? any advances that are currently being tested? damn we need to enter the space age!

This is how it works. The closest star to earth is about 4 light-years away, this means that if you look at it tonight, you are actually seeing the light of that star from 4 years ago. If you look at it 4 years from now, you will be seeing the light it emitted today.
For stars that are 20 light years away, in 20 years you will see the light that it emitted today.
