The exotic cosmic objects known as
ultraluminous X - ray sources
produce some 10 million times more energy than the Sun . But what is really striking is that
they break the laws of physics
, and the reference is to the so - called
, which baffles scientists . scientists.
Precisely this limit regulates precisely to what point an object can shine in relation to its size.
According to scientists, if something were to break it, the energy released
would blow it apart
Which, of course, is not the case with ULXs, which
according to NASA
"regularly exceed the Eddington limit between 100 and 500 times, leaving scientists baffled."
The finding that breaks the laws of physics and baffles scientists.
Observations with X-ray telescopes carried out by the North American agency and recently published in
The Astrophysical Journal
confirm that the extraordinary brightness of a particular ULX, called M82 X-2, is absolutely real, and not some kind of optical illusion as suggested some previous theories-
In addition, according to ABC
, they also confirm that it greatly exceeds the Eddington limit.
How can you break the laws of physics?
According to what specialists divulge, there is a hypothesis that suggests that
this impossible brightness
is due to the strong magnetic fields of the ULX.
The cosmic source puzzles scientists.
However, scientists can only prove this idea through observations: Up to
billions of times more powerful than the
strongest magnets ever made on Planet Earth, ULX magnetic fields
cannot be reproduced
in a laboratory.
What is the Eddington limit
Particles of light or photons exert a small push when they are emitted.
So if any cosmic object (for example, an ULX) emits a sufficient amount of light per square meter, the outward push of the photons can overcome the inward pressure of gravity that tries to compress it, summarizes Infoterio .
This is precisely the Eddington limit.
And when it is reached, the light from the object acquires enough force to
push any gas or material that tries to fall towards it.
This change is very significant, because the material that falls on an ULX is, at the same time,
the source of its brightness.
It's the same thing that happens with
: when their strong gravity pulls in surrounding gas and dust, those materials accelerate, heat up, and start radiating light.
they are not black holes
thought that ULXs were black holes surrounded by glowing rings of gas
But in 2014, data from the NuSTAR Telescope Network revealed that M82 X-2 is not a black hole, but a
These are formed when a star dies and collapses, squeezing one or more solar masses into an area not much larger than an average-sized city.
This incredible density also creates an exceptional gravitational pull on the surface of the neutron star, about 100 trillion times stronger than that of Earth.
A supermassive black hole.
The researchers have now returned to studying M82 X-2, and apart from confirming that its brightness is not an illusion,
they discovered that this neutron star is 'parasitizing' a nearby star
Based on the amount of material hitting the neutron star's surface, scientists were able to estimate how bright the ULX should be, and their calculations matched independent measurements of its brightness.
Thus, they confirmed that
M82 X-2 exceeds the Eddington limit.
