Remembering Stephen Hawking on his 4th death anniversary

British physicist Stephen Hawking passed away on 14 March, in the year 2018. 

Contribution of Stephen Hawking to the scientific world:

Remembering him on his death anniversary, here are a few ground-breaking discoveries that can be attributed to the phenomenal scientist and inspiring human being.

• Proving Black Holes:
• He was the first person to ever provide mathematical proof for the existence of black holes.
• They had been a theory before Hawking’s validation.
• The Hawking Radiation:
• His prediction that black holes emit radiation was found true and named after him.
• Thanks to these predictions, we now know black holes can vary in size in accordance to the radiation of energy.
• Hawking Area Theorem:
• This was a team effort with Brandon Carter and James Bardeen. Together, they discovered the laws of the mechanics of black holes.
• The first of these was named after Hawking, which says the black hole never gets smaller in terms of total surface area.
• Formation of Black Holes:
• Apart from discovering their existence, Hawking also postulated how they were formed.
• As a star dies, its entire mass collapses into infinite density at a single point (or singularity) which in turn forms a black hole.
• The Theory of Time:
• His theories regarding time are quite interesting.
• One of the many time-related theories he offered was that before the Big Bang explosion (widely accepted as the event leading to the birth of our current universe) time was basically non-existent.
• This means questions regarding “what existed or happen before” this event is essentially meaningless.
