By the way you can understand that our galaxi is made of bilions stars just looking at the sky ?
I would like to have your sight
No, but it's totally easy to understand how there must be huge distances involved, even between any random pair of two stars you can see.
In fact, calculating distances between stars doesn't require seeing all stars and you don't need to have a good eyesight as long as you can see the stars you are tracking on their different locations within one (or more) year(s).
It's basically how the Egyptians, Mayans and so on calculated how celestial bodies move.
May be someone wonder who is that guy who agrees with fastline but disagrees with an article written by a scientists of the "Niels Bohr Institute in Copenhagen, Denmark"
accepted by the "International Journal of Astrobiology " and published by "Cambridge University Press 20 Apr 2007"
Here are his credentials :
" more than 10 years' experience in media, arts and communications "
Well, maybe that's because not every person, regardless of their excellent credentials, can be right all the time... Remember all the guys with so called good credentials and credible psychological records that report having seen Ufos? Same story... they may or may not have seen what they think they have seen, but in the end it doesn't prove anything.
