Black holes are the most peculiar phenomena of the universe. These strange entities present a gravitational acceleration so strong that nothing, even light, can escape. But NASA scientists now believe that a black hole dubbed V404 Cygni has propelled astronomical strangeness to another level.
Most black holes are believed to spit plasma jets from its poles.
However, the Cygni black hole V404 was discovered 8,000 light-years away from the Earth, blasting plasma jets while its gravitational pull was pulling the tissue of space-time itself.
Spacetime merges the three dimensions of space and the unique dimension of time into a single four-dimensional continuum.
The counter-intuitive concept is a way to understand relativistic effects such as why different observers perceive where and when different events occur.

Professor Greg Sivakoff, a researcher at the University of Alberta, said, "We were upset by what we saw in this system – it was completely unexpected.
"The discovery of this astronomical first deepened our understanding of black hole operation and galaxy formation.
"That tells us a bit more about this big question:" How did we get here? "
A detailed analysis of the bizarre behavior of the V404 Cygni was made possible only with data captured by the Very Long Baseline Interferometer.

Professor James Miller-Jones, of the International Center for Research in Radioastronomy, said: "Like many black holes, it feeds on a nearby star, removes gas from the star and forms a disc of matter surrounding the black hole and the spirals. towards her under gravity.
"What's different about V404 Cygni is that we think the material disk and the black hole are misaligned.
"This seems to cause an oscillation of the inner part of the disc like a top and the projection of jets in different directions as it changes orientation."
The discovery of shock has led some observers to wonder if the black hole was an opportunity to travel back in time.

Albert Einstein's theory of special relativity states that a surprising thing happens when you travel in space-time, especially when your speed relative to other objects is close to the speed of light.
Time passes more slowly for you than for the people you left behind.
And you will not notice this effect until you return to those motionless people.
A kind of time travel also occurs for objects in gravitational fields. Einstein's theory of general relativity predicts that time passes more slowly for objects in gravitational fields – as here on Earth – than for objects distant from such fields.
So there are all kinds of spatio-temporal distortions near black holes, where gravity can be very intense.
