Stephen Hawking speaks on Facebook; Congratulations Mark Zuckerberg!

The Stephen Hawking, noted Theoretical Physicist joined Facebook today. Within no time during the time of writing this article his page has 1,151,476 likes. I think record number of likes in shortest time period, not sure. Hope Facebook will release something in future or someone else will dissect this aspect. Time vs Hawking Liking :) Welcome Sir, thank you to come in open, and meet people. And Congratulations Mark Zuckerberg and Company.
