First post in Big Rip Theory

Big Rip

In physical cosmology, the Big Rip is a hypothetical cosmological modelconcerning 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 singularitiesand crunch or rip singularities occur only for hypothetical matter with implausible physical properties.

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.

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
