Mathematician Roy Kerr predicted space travel through black holes

Published

on

Back in 1963, even before the official confirmation of the existence of black holes , the New Zealand mathematician Roy Patrick Kerr , who at that time was only 29 years old, was able to solve the equations of Albert Einstein and describe the gravitational field of a rotating black hole.

The gray-haired scientists were so delighted with the work of Kerr that they themselves became interested in studying black holes, which at that time were considered only hypothetical objects.

Kerr, continuing to “conjure” Einstein’s equations, proved that during the collapse of a massive star, a rapidly rotating ring of gas and dust is formed.

The gravitational forces of the collapsing star are trying to break the ring, but the speed of rotation is so huge that the ring remains stable, overcoming gravity.

The first image to be captured of a black hole (on the left) has proved a New Zealand mathematician’s work to be true. More than 50 years ago Professor Roy Kerr, solved the equations describing rotating black holes.

Speed ​​and gravity

Kerr grew older, gained new knowledge and absorbed experience, continuing to work with Einstein’s equations. A promising scientist proved that gravity in the center of the ring is incredibly strong (in fact, he predicted the presence of a black hole), but still finite.

According to his calculations, if you accelerate to near-light speed, you can fly through the ring through and… get into another universe. If the ring is large enough, the journey will be very safe and comfortable.

Kerr’s colleagues liked the way he started, but they were annoyed by the scientist’s subsequent conclusions; they began to “gut” Kerr’s decisions, hoping to find errors and quickly get rid of what did not fit in their heads.

However, the actions of mathematicians only strengthened Kerr’s conclusions.

A desperate space traveler, approaching a rapidly spinning black hole at great speed, could bypass the event horizon and “fly out” in some other corner of the Universe. Of course, he would cut off his way back, but the experience of such a journey would be unforgettable.

Just imagine: you fly into a black hole at a huge speed, experience a moderate effect of tidal forces and “pop!” In a minute, you are already a million light-years from Earth. Creepy and cool at the same time!

Was Roy Kerr right?

Today it is known that black holes are real objects, and the ring described by Kerr is an accretion disk that “outlines” the outline of a black hole.

Yes, the scientist was right in many respects, but is he right that black holes are portals to other parts of the Universe or even to other worlds?

Unfortunately, there is no definite answer, but if humanity does not self-destruct, then, undoubtedly, one day it will solve this riddle.

‘October Surprise’: Russia To Launch Nukes in Space

Published

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.

Our
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
apart.

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.

His
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.

Based on
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
clouds.
