To spot the black hole's event horizon, a team of astronomers — led by Michael Garcia and Ramesh Narayan of the Harvard - Smithsonian Center for Astrophysics in Cambridge, Massachusetts — watched what
happened as a black hole stole gas away from a nearby star.
Not exact matches
So they're kind of the same in some deep mathematical sense, and
as of today we don't really know what
happens at the center of a
black hole and we don't really know what
happened at the moment of the big bang so these are two puzzles that are cousins of one another and anything that we learn about one is certainly going to shed light on the other.»
Sometimes thought leads nowhere,
as in considerations of what
happens to information absorbed by a
black hole.
This is intriguing, but,
as long
as the
black hole continues to exist, we do not need to worry about what might have
happened to the information, or entropy, associated with the original star.
A
black hole arises when the warping around a point grows so severe that that spacetime in the area becomes like a funnel so steep that nothing can climb back out,
as may
happen when a massive star collapses.
«But I don't think we can explore that question without looking at what is
happening at the inflationary zone inside
black holes and trying to understand the physics
as best we can.»
As with Las Vegas, what
happens in a
black hole stays in a
black hole.
Specifically, in this work he has applied geometric structures similar to those of a crystal or graphene layer, not typically used to describe
black holes, since these geometries better match what
happens inside a
black hole: «Just
as crystals have imperfections in their microscopic structure, the central region of a
black hole can be interpreted
as an anomaly in space - time, which requires new geometric elements in order to be able to describe them more precisely.
The feeding process is somewhat similar to what
happens around supermassive
black holes, but isn't
as big and messy.
But
as many
as half of
black hole births may
happen more stealthily, with no explosion to mark the event.
Such a «theory of everything» would unite all the forces of nature and explain why time and space exist,
as well
as answering such trifles
as how the Universe began and what
happens at the centre of a
black hole.
«Some years ago we may have thought of [
black holes]
as surly loners sucking their thumb in the corner and gobbling anything that
happened to come by,» Miller says.
However,
as we haven't been able to directly see what's
happening close to the
black hole's event horizon, how this accretion works has been a mystery.
This latest detection originated from a merger creating a
black hole of 49 solar masses (another «heavy»
black hole like the first one), but the merger
happened over twice
as far away than previous events.
Set in the distant future, The
Black Hole features a crew of five, as well as a rambunctious robot, who happen upon a mysterious black hole in their space vessel, the Palo
Black Hole features a crew of five, as well as a rambunctious robot, who happen upon a mysterious black hole in their space vessel, the Palom
Hole features a crew of five,
as well
as a rambunctious robot, who
happen upon a mysterious
black hole in their space vessel, the Palo
black hole in their space vessel, the Palom
hole in their space vessel, the Palomino.
The
black holes are people who
happen to hit retirement age at the start of a downturn, such
as in 1929, 1946 and 1973.
It may not be a Hadron Collider (the less said about
black holes and anti-matter the better), but whilst it won't enlighten us
as to what
happened at the beginning of time, it will shed some light on the subject at hand, and it's a lot funnier.
