Quantum tunnel it is a new concept of modern physics. Since last decade quantum mechanics is successor over classical physics rules at quantum level. It will help us better for understanding of matter. Starting from matter, it a composition of atoms , nuclei , nucleons , electron, etc. their size from 10^-11 to 10^-15 . At this quantum level ,long range forces (like Gravity)become very weak. And strong forces like nuclear force, Wander waal force ( little weak) , Electrostatic force , Inter-atomic force of Gluons came up. Due to this it changes the whole structure of time at quantum level. Let's us understand how it works -- Nucleus is final density of matter it is equivalent to density of atom at center of Black holes,or other stellar bodies in universe. According to theory of Relativity , gravitational force can bend space and time and increase in gravitational forces literally Squeeze time and space. ( Ex: any stellar massive body) . Then what is its relation to Quantum le...

SCIENTISTS have fount evidence for a large number of double supermassive black holes,likely precursors of gigantic black hole merging events. The research published in the Journal monthly notices of Royal astronomical society,confirm the current understanding of cosmological evolution-- that Galaxy and their associated black hole merger over time, forming bigger and bigger galaxy and black holes.Astronomers from the university of Hertfordshire in the UK and colleagues look at radio map of powerful Jet sources and found signs that would usually be present when looking at black holes that are closely orbiting each other.
Before black hole merge they form a binary black hole , where the two black hole orbit around each other. Gravitational wave telescopes have been able to find evidence of the merging of small black hole since 2015, by measuring strong burst of gravitational waves that are emitted when binary black hole merge. However current technology cannot be used to demonstrate the presence of super massive binary black hole.
Supermassive massive black holes emit powerful jets. When supermassive binary black holes orbit, it causes jet emanating from the nucleus of a galaxy to periodically change in direction. Astronomers studied the direction that this jets are emitted in,and variance in these directions. They compared the direction of the jets with the one of the radio lobes (that store all the particles that ever went through the jet channel) to demonstrate that this method can be used to indicate the presence of supermassive binary black holes.
"We have studied the jets in different conditions for a long time with computer simulations," said Martin Krause from the university of Hertfordshire.
" In this first systematic comparison to high resolution radio map of most powerful radio sources, we were astonished to find signatures that were compatible with jet precession in three quarters of the sources,"Krause said.The fact that the most powerful jets are associated with binary black holes could have important consequence for the formation of the stars in the galaxies; stars form from the cold gases, jets heat this gases and thus suppress the formation of stars. A jet that always heads in the same direction only heats limited amount of gas in its vicinity, researchers said.
They can heat much more gas, suppressing the formation of stars much more efficiently, and thus contributing towards keeping the number of stars in the galaxies within the observed limits.
