Quora
It’s kind of ironic that I’m thanking Quora here, yet, I feel grateful to the person who prompted me to join Quora. Unfortunately, I don’t remember this person and this would be a gratitude offered in the open, let free in the infinite horizon of social media, hoping that he/she gets it somehow.
Why am I grateful to this person? Because I feel so much more knowledgeable on so many things, all thanks to Quora. All it takes is to follow the right people and read as much as you can.

This was answered by scientist at NASA. (If you want to know the answer, get on Quora and follow Robert Frost :) )
