But it's hard to begrudge the cutesy ending sequence, just like it's hard to resist the way the film brings out the children for sentimental effect and features visual motifs inspired by Stephen's
theory about black holes.
A collaboration with colleague Jacob Bekenstein, the formula paved the way for further
theories about black holes.

Their findings dispel the so - called firewall paradox which shocked the physics community when it was announced in 2012 since its predictions
about large
black holes contradicted Einstein's crowning achievement — the
theory of general relativity.

The idea of matter escaping the alleged point - of - no - return was surprising (it's a central plot point in that other recent movie
about black holes, the biographical The
Theory of Everything), but the fate of information that falls into the
black hole was what really troubled Hawking's colleagues.
This was a major triumph for string
theory because it could do something — offer clues
about a
black hole's inner makeup — that no other approach could.
Until we have a
theory that effectively integrates quantum mechanics and gravity, theoretical physicists are likely to remain almost as puzzled as everyone else
about what goes on at the heart of a
black hole — although that hasn't stopped them from trying to work it out.
That journey started in earnest when he heard
about the counterintuitive notion that
black hole theories might apply to other phenomena in different settings.
According to relativity
theory, information
about what falls into a
black hole is forever lost.
This behavior aligns with Albert Einstein's predictions
about extreme gravity near rotating
black holes, published in his famous
theory of general relativity.
That is of interest because there are competing
theories about what would happen to such
black holes.
Theories of stellar evolution predict that stars weighing less than
about 25 times the mass of the sun end up as neutron stars, while heftier stars are destined to become
black holes.
In a new study in the journal Nature Astronomy, a team of researchers from Dublin City University, Columbia University, Georgia Tech, and the University of Helsinki, add evidence to one
theory of how these ancient
black holes,
about a billion times heavier than our sun, may have formed and quickly put on weight.
Joseph Polchinski, Firewall Institution: University of California, Santa Barbara Year: 2012 Known for: Discovering D - branes, explaining what D - branes are (a string
theory thing) Idea: Once a
black hole has lost
about half of itself to Hawking radiation, the event horizon can no longer store enough encoded information to tell the story of what's inside.
The characteristics of the surrounding stars suggest that although the magnetar's progenitor probably reached 40 solar masses at one point, it shed its mass so quickly that when the star exploded it fell under the 20 - solar - mass limit, thereby creating a magnetar instead of a
black hole — and conforming to current
theory about stellar evolution.
That's
about twice as massive as they should be, according to current
theories of how
black holes form from stars.
Unlike Einstein's
theories, which have been confirmed many times by experiment, Hawking's ideas
about singularities and
black hole evaporation will probably never be observed.
Light from the collision should help test Einstein's
theory of general relativity, and tell us more
about two huge bubbles of hot gas at the centre of the Milky Way that the
black hole may have spawned.
Since then, there have been many
theories about the structure and emission mechanism of Sgr A *, but, in the past few years, astronomers have found increasing evidence that it is a supermassive
black hole.
Gravitational waves — ripples in the fabric of space and time produced by dramatic events in the universe, such as merging
black holes, and predicted as a consequence of Albert Einstein's 1915 general
theory of relativity — carry information
about their origins and
about the nature of gravity that can not otherwise be obtained.
COSMOS - A Spacetime Odyssey's presenter / co-writer talks
about Stephen Hawking's
black hole theory, known as «Hawking Radiation».
If further data support this observation, it could mark the first confirmed finding of a primordial
black hole, guiding
theories about the beginnings of the universe.
What is so fascinating
about the primordial
black hole theory of Garcia - Bellido and Clesse is that it will be tested with current and future instruments.
We are understanding a little more
about the Super Massive
Black Hole at the centre of our galaxy and observations are also revealing that Einstein was right
about his
theory of general relativity.
However, both explanations directly contradict
theories about how
black holes formed and grew in the early universe.
Bryan, you are perhaps unaware of the Big Bang vs Steady State rows, the rows
about existence of
black holes, the rows
about the causes of active galactic nuclei, the current rows
about inflationary
theory (which touch on your reference to dark matter).
