Does Authority minified?

[zant]

I have website with authority 50, I put one link for a site, How much will this site take from my authority? , Will this authority minify from my website?

What if I put two links to 2 website, how much everyone will take?

First thing: Your sites authority will not decrease because you add an external link (otherwise no one would ever link)

Second thing: Exactly how much is passed is a little hard to determine and is not revealed by Moz, someone asked a similar question earlier this month and this has got some great responses and I don't want to duplicate their work
