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
Exoplanets which are between two to four times the size of earth are likely to have vast amounts of water, according to a study that may have implications for the search of Alien life in our Galaxy.
Data from the exoplanet hunting Kepler space Telescope and Gaia mission indicates that many of the known planets may contain as much as 50 % of water. This is much more than the earth's 0.02% water content, researchers said.
"It was huge surprise to realize that there must be so many water worlds," said Li Zeng from Harvard University in US.
Scientists have found that many of the 4000 confirmed or candidate exoplanets discovered so far fall into size categories: those with the planetary radius averaging around 1.5 that of earth, and those averaging around 2.5 times the radius of the earth. After analyzing the exoplanet with mass measurements and recent radius measurements from the Gaia satellite, scientists have developed a model of their internal structure.
"We have looked at how mass relates to radius, and developed a model which might explain the relationship,"said Zeng.
The model indicates that those exoplanets which have a radius of around x1.5 earth radius tend to be rocky planets ( of typically x5 the mass of the earth ) , while those with radius of x2.5 earth are probably water worlds".
"This is water , but not as commonly found on here earth",said Zeng."there surface temperature is expected to be in the 200 to 500 degree Celsius range. Their surface may be shrouded in a water vapor dominated atmosphere.
