Life

Stephen Hawking was born in January 1942 .. At that time, London was under attack during the Second World War, his mother went to Oxford to give birth in greater safety.

Hawking went up to Oxford in 1959 at the age of 17.[

In 1962.,he began his graduate work at Cambridge.

But soon the diagnosis of motor neurone disease came when Hawking was 21. At the time doctors gave him a life expectancy of two years.At first, Hawking was shocked and upset. He could not find a reason for living before he met his wife Jane Wilde.

In 1965 Hawkin g married Jane Wilde at Cambridge

In 1966,he completed his doctorate and go on working at Cambridge until now.

singularity theorem

Hawking extended the singularity theorem concepts and showed that the classical concept of time must have begun with a singularity at the Big Bang, and thus the Universe existed at one time in a hot dense state.

This is Hawking’s major world wide contribution to Big Bang cosmology.

black hole

A black hole is a region of space-time from which gravity prevents anything, including light, from escaping. But Hawking’s results, which he presented from 1974, showed that black holes emit radiation, known today as Hawking radiation, which may continue until they exhaust their energy .

He has written books that make these complex subjects easier to understand.

A Brief History of Time attempts to explain a range of subjects in cosmology, including the Big Bang and black holes , to the nonspecialist reader. Its main goal is to give an overview of the subject but, unusual for a popular science book, it also attempts to explain some complex mathematics.
