Just the other day I was intently watching a feature of Stephen Hawking on TV and couldn't help admiring the man for his profoundness in passion and the ability to dream outside permissible limits, such as for instance, time travel! He has always fascinated me, and that began several years ago, when I first read his very articulate account of the universe, space and time, titled 'A brief history of time,' which, most certainly, is a very authoritative text on the four dimensions that we surround our existence in!
It amazes me beyond imagination how someone so severely disabled, (by motor neurone disease also known as amyotrophic lateral sclerosis or ALS), continues to delve into the nuances of space and time with a sense of ease and passion like that employed by a child during it's course of play.
What is certainly commendable about him is his ability to transcend boundaries despite his massive incapacity! Sometime in early 2007, he became the first paralytic to undertake a zero gravity flight as a precursor to his sub-orbital flight in space, which I'm not sure has happened yet.
Perhaps, the two things I absolutely like about him are, among others, one, his belief that alien life does exist in other parts of the universe, and two, his answer to the question of 'What came before the Big Bang?' which he asserted was meaningless, when he compared it to asking 'What lies north of the North Pole?'
