He didn't. Although Hawking has done an immense amount of theoretical work on black holes, as well as the topology of our Universe, he has always taken Big Bang Cosmology as his starting point. That's because, by the time he got his PhD in 1966, observational evidence had pretty much ruled out any cosmology but Big Bang. Hawking has simply improved our mathematical understanding of BBC.
That is a complicated matter.Black holes are usually the result of matter being concentrated to such a degree that it collapses gravitationally, and produces an event horizon, a sphere of influence in which the escape velocity exceeds the speed of light.But it is possible that black holes were produced during the Big Bang not as a results of concentrations of matter, but as flaws in the development of space/time itself. Some such flaws may be one-dimensional: cosmic string. Others may be zero-dimensional: they would be tiny singularities. Most such black holes will, according to current theory, have evaporated by now.

The density of matter just after the big bang is calculated to be sufficient to have spontaneously created black holes; such are called primordial black holes, and searches for their existence are ongoing.
Bang Bang Machine was created in 1989.
A singularity is a situation in which a certain mass (usually a large mass) is concentrated in ZERO volume, resulting in an infinite density. This can happen, in certain theories, for black holes, and as the initial conditions of the Big Bang. Physicists generally believe that such singularities don't really exist, and that, if singularities to appear in some formula, they represent a failure of the corresponding theory at extreme conditions.
Hello, i am minakshi so, the big bang theory as currently postulated incomplete because the big bang theory does not answers about the questions that what happened or what was there before the big bang ? it also does not tells about the singularities,that what is singularities, and why the laws of physics are not implied on it.
The Big Bang almost certainly did occur.A singularity, on the other hand - whether it is the singularity of the Big Bang, or the singularity in a black hole - probably indicates that something is incomplete in our current understanding of physics.

no black holes are stars
No. The Big Bang was an event, not a material thing. (There are plenty of other ways in which it is utterly unlike a black hole as well.)
Actually one interpretation of the big bang is as a white hole, the inverse of a black hole.
One of the considerations for the eventual termination of the universe is that all matter will be pulled into black holes, and then these black holes would eventually evaporate.
scientists think that the Big Bang which generated the univerese waas the consequence of the explosion of a massive black hole. so the big bang
