Interstellar is possibly one of the most gorgeous space epics of all
time. The cinematic genius of Christopher Nolan produced an intriguing
psychological and engineering journey, giving us a glimpse of a
cinematic representation of a black hole — the dying star, Gargantua.
Pleasantly, a report published by Gizmodo has revealed a piece of detail
from the movie — its portrayal of the black hole was actually
strikingly close to the reality. Coming on the back of the first ever
black hole image shared by the Event Horizon Telescope’s team of
scientists, it is quite a feat of scientific accuracy, and the
scientific facts mentioned in it are equally amazing.To get more news about

According to the report, Gargantua in Interstellar is an incredibly
close representation of an actual black hole, and while it does seem
quite different from the reconstructed image of the M87 black hole that
we saw yesterday, the two are quite similar in multiple ways. To
understand this, it is first important to understand a major point of
difference — the black hole from Interstellar had a thin strip of light
matter around its middle, in appearance similar to how rings around a
planet looks like. Furthermore, Gargantua in Interstellar had a more
prominent, definite photon circle, while the light in the image stitched
together by the Event Horizon Telescope (EHT) has a fainter print.
Interstellar also portrayed a more uniform light circle around the black
hole, while the real black hole’s image shows irregularity in the
photon circle around it.
For the first point of difference, the main reason is that while we
got a frontal view of the black hole in Interstellar, the M87 black hole
was viewed by us from close to its poles. As a result, the strip of
matter across the centre of the black hole that we observed in a galaxy
that is not too far, far away appeared in the extended light circle
surrounding the centre of the black hole. The tilted angle at its poles
where we observed the black hole also explain the irregularity in the
photon circle that can be seen around the dying star. As a result, the
strip of light matter streaking through the centre of Gargantua is quite
close to factual accuracy, absolute confirmation of which we shall find
in the coming months, with continued observation of it and the
Sagittarius-A black hole, by the EHT.
Furthermore, the real image of the black hole shows different
intensities of light around its top-left edge, with a brighter crescent
towards the bottom-right. The explanation for this is that while this
supermassive black hole is collapsing, it is also spinning. As a result,
the light around it would be spinning, with spacetime warping around
it. As a result, there are two parts of the spin — one, where light is
speeding towards us, and the other, where light is being thrown in a
direction opposite to us. This explains the optical difference in the
real image, since the spin creates a significant difference in the
amount of time that the two light sources take to travel to Earth.
In Interstellar, this one detail was not included, because
cinematically speaking, we were looking at the black hole at a much
closer distance, in comparison to what we saw from Earth. Because of
this, light will have taken much lesser distance to travel from source
to point of incidence. Furthermore, the intensity of light would be
much, much higher at closer quarters. Because of this, the appearance of
the photon ring around the black hole would look fairly uniform if you
were to, hypothetically take a straight-up look at it from up close.
This, of course, is taking into account if you manage to resist forces
that lead to light bending in with such immense gravitational pull.
As a result, while the black hole image of the M87’s dying star is
the absolute reality, it appears that the cinematic representation of
one, roughly four years before we caught our first glimpse of an actual
dying star, was rather close to reality. Of course, there were certain
discrepancies such as incidental light properties and the way it behaves
in space, in comparison to what was shown on screen, but for the large
part, Nolan’s bit of scientific research work around black holes was
very, very close to reality.
