Hello ✋🙋🙋🙋🙋✋✋✋ My Name is Aman Kumar I'm a student And I'm going to start a book written by me in my mind I'm not a professional writer this is my first time.This book is research of m y 8 years. OK i know u all thinking hmm.. Fak raha hai 8 saal lie no its not lie its true ye book meri invention hai to all human kind. Kya tum Saab ke maan me ye saval (question) nahi aata   ke ye universe kha se aye hum kaise aye kya hua hooga ki ye infinite( anant ) bramhand baana hoga aur humara ghar yani ( Dharti ) earth baani hogi kitna samye laga hoga is puure universe k o banne me kabhi is subject par vichar kara hai nahi kia hooga paata hai aaj kal ka moto nahi motorola nahi ( aaj kal ka suvichar yaar apple ne iPhone x launch kar diya Samsung ne s9 launch kar diya Intel ka naya processer i9 a gaya baas yahi par dimaag ke puri power khatam nahi yaar humare pass sirf 100 saal hai bolne ko ke insaan ke umar

First post in Big Rip Theory

Big Rip In  physical cosmology , the Big Rip is a  hypothetical   cosmological model concerning the  ultimate fate of the universe , in which the  matter  of the  universe , from stars and galaxies to atoms and subatomic particles, and even  spacetime  itself, is progressively torn apart by the  expansion of the universe  at a certain time in the future. According to the hypothesis, first published in 2003, the  scale factor  of the universe and with it all distances in the universe, which is known to be increasing, will be found to increase exponentially. If this were to happen, the model speculates that eventually in many billions of years' time the scale factor would become  infinitely  large, pulling even subatomic particles and the fabric of  spacetime  apart, and ending our universe. The possibility of sudden  singularities and crunch or rip singularities occur only for hypothetical matter with implausible physical properties.

Goldilocks Zone (part-2)

Is presence in Goldilocks belt enough for having life on a planet? No, besides distance from the sun, if the atmospheric condition of the planet is accurate to form and sustain water to its surface, can only have the possibility of life. For instance, like Earth and Mars, Venus too considered in the habitable zone of the sun, but life chosen the earth only. Why? NASA's Mars rover mission evidences the ancient bacterial life on mars . Later, due to the thin atmospheric layer it was not able to sustain water to its surface. On the other hand, Venus is too hot to origin the life. Its atmosphere consist a very thick layer of carbon dioxide. It absorbs sun energy and restricts revert it back, thus create a non habitable furnace.   Bottlenecks for origin of life in the Goldilocks zoned planets: Billions planets in such zones in the universe orbit around different stars. For instance, NASA claims its recently discovered  TRAPPIST-1 planetary system have perfect chances of alien life
