If wormholes exist in space, they are very similar to black holes, physicists say. This raises the possibility that we could see them without knowing it.
The universe is full of exciting things, like black holes or merging neutron stars. However, all this looks trite compared to what scientists call wormholes, which hypothetically connect parts of space in different parts of the universe.
Many physicists are skeptical that wormholes exist, or at least that three-dimensional objects can pass through them unharmed.
As telescopes develop, a more and more exciting question arises: if wormholes exist, why have we never discovered them? Four Bulgarian physicists believe that perhaps we simply did not recognize them.
Most of the black holes we’ve identified are known either from their gravitational effects on the stars around them or from the jets of material ejected from their accretion disks. If any of them were indeed wormholes, we would be unlikely to know about it.
However, observing the polarization around M87* with the Event Horizon Telescope and its follow-up to Sagittarius A* is another matter entirely. In these cases, we saw the shadow of the object itself on its event horizon and hoped to spot something that looked like a wormhole.
The possibility of wormholes excites physicists, however, as Petya Nedkova and co-authors of the study from Sofia University note, we do not know what they might look like.
Scientists in their study are trying to solve this problem and come to the conclusion that, when viewed from a large angle, wormholes will not look like anything we have previously seen.
However, the authors believe that at low tilt angles, the wormhole will have a “very similar polarization pattern” to a black hole. Therefore, M87*, seen at the assumed angle of 17°, could be a wormhole and we would not know it.
This does not mean that we are absolutely unable to distinguish between wormholes and black holes.
“More significant differences are observed for highly lensed indirect images, where the polarization intensity of a wormhole can increase by an order of magnitude compared to a black hole,” the authors write.
The lensing does not come from a massive object between us and the hole creating a gravitational lens. The photons’ trajectories are distorted by the hole’s huge gravitational field, causing them to make a partial loop around the hole before heading towards us.
The situation becomes even more complicated if we assume that matter or light can pass through the wormhole in any direction. If so, then signals from the area outside the entrance are able to reach us.
They will change the polarized image of the disk that we see around the hole, while the light coming from another place will have different polarization properties. This can provide what the authors call “a characteristic signature for wormhole geometry detection.”
The authors of the study acknowledge that their findings are based on a “simplified model of a ring of magnetized fluid” orbiting a black hole. More advanced models will help identify differences and use them to distinguish a wormhole from a black hole in other ways.

‘October Surprise’: Russia To Launch Nukes in Space
The ‘national security threat’ announced on Wednesday is
about Russia planning to launch nuclear weapons in space, causing some
to speculate whether it’s really an election year ploy.
The panic began when House Intelligence Committee Chair Mike Turner
(R-Ohio) asked President Biden to declassify information about a
“serious national security threat”.
Modernity.news reports: The weapon would reportedly be designed to be used to take out satellites.
Speaker Mike Johnson (R-La.) responded by telling reporters he wanted “to assure the American people, there is no need for public alarm.”
The big, scary threat is serious business and involves a space-based nuke controlled by evil dictator Putin, but it’s also “not an immediate crisis,” according to what three members of the U.S. House Intelligence Committee have told Politico.
Okay, then. Just for election season, is it?
Zero Hedge reports: “So, the question is – was this:
a) a distraction from Biden’s broken brain, or
2) a last desperate attempt to get more funding for anything-but-the-US-border, or
iii) a path to pitching Putin as the uber-bad-guy again after his interview with Tucker Carlson.”
Just by coincidence, Mike Turner recently returned from Ukraine having lobbied for billions more in weapons and aid for Zelensky’s government.
Some questioned the timing, suggesting it might all be a deep state plot to keep American voters afraid when they hit the ballot box.
Speculation will now rage as to whether this is “the event,” real or imagined, that billionaires and elitists the world over have been building underground survival bunkers in preparation for.
Earth has built-in protection from asteroids
Asteroids are not just wandering space rocks, but a potential threat
to Earth. But what if the Earth already has its own built-in defenses
against them? Recent research published on the preprint server arXiv puts forward an unusual theory: Earth’s gravitational forces may serve as its secret shield against asteroids.
planet uses powerful gravitational interactions with other celestial
bodies to break apart asteroids that approach it. These tidal forces,
akin to those that explain Earth’s tides caused by the Moon, can be so
intense that objects undergo tidal disruption, causing them to be torn
Observations of fragments of Comet Shoemaker-Levy 9 after
its collision with Jupiter in 1994 provided the first confirmation of
this phenomenon. However, for decades astronomers have been looking for
evidence that Earth or other terrestrial planets could have a similar
effect on asteroids and comets.
Planetary scientist Mikael Granvik
from the Swedish University of Technology, Luleå, led the research that
came closer to solving the above phenomenon.
discovery is linked to the search for gravitationally disrupted
near-Earth asteroids (NEAS), and provides compelling evidence that our
planet’s gravitational forces are not just an abstract concept, but a
factor capable of breaking asteroids into small pieces.
modeling of asteroid trajectories, Grunwick and colleague Kevin Walsh of
the Southwest Research Institute found that collisions with rocky
planets can cause asteroids to lose a significant portion of their mass,
turning them into debris streams.
New data shows that small
asteroid fragments, while not posing a threat to life on the planet, may
nevertheless increase the likelihood of local collisions like those
that occurred in Tunguska and Chelyabinsk.
Granwick assures that
asteroids smaller than 1 km in diameter are not a critical threat, but
increase the likelihood of incidents. However, it is worth remembering
the additional risks that may arise due to the formation of new debris
