Title: Stephen Hawking's expanding universes thesis breaks the internet :
Post by: Mohammad Mahedi Hasan on November 05, 2017, 11:14:08 AM

Stephen Hawking’s 1966 doctoral thesis has broken the internet after becoming available to the general public for the first time.

Demand for the thesis, entitled Properties of Expanding Universes, was so great on Monday that it caused Cambridge University’s repository site to go down. The site was still inaccessible at 7.30pm on Monday.

The “historic and compelling” thesis had swiftly become the most-requested item in Cambridge’s open access repository, Apollo.

The university made the essay public at midnight on Sunday to mark Open Access Week after hundreds of readers sent in requests to download Hawking’s thesis in full.

A University of Cambridge spokesperson said: “We have had a huge response to Prof Hawking’s decision to make his PhD thesis publicly available to download, with almost 60,000 downloads in less than 24 hours.

“As a result, visitors to our Open Access site may find that it is performing slower than usual and may at times be temporarily unavailable.”

The work considers implications and consequences of the expansion of the universe, and its conclusions include that galaxies cannot be formed through the growth of perturbations that were initially small.

However, until the university increases the website’s capacity to deal with requests, or demand falls, the paper is likely remain unavailable to many of those trying to access it.

Some implications and consequences of the expansion of the universe are examined. In Chapter 1 it is shown that this expansion creates grave difficulties for the Hoyle-Narlikar theory of gravitation. Chapter 2 deals with perturbations of an expanding homogeneous and isotropic universe. The conclusion is reached that galaxies cannot be formed as a result of the growth of perturbations that were initially small. The propagation and absorption of gravitational radiation is also investigated in this approximation. In Chapter 3 gravitational radiation in an expanding universe is examined by a method of asymptotic expansions. The 'peeling off' behaviour and the asymptotic group are derived. Chapter 4 deals with the occurrence of singularities in cosmological models. It is shown that a singularity is inevitable provided that certain very general conditions are satisfied.
