The Great Escape


The Great Escape is a 1963 Holliwood film about an escape by Allied prisoners of war from a German Prisoners of War camp during World War II, starring Steve McQueen, James Garner and Richard Attenborough and directed by John Sturges. The film is based on a real story of the mass escape from Stalag Luft III in Sagan, Poland, in the province of Lower Silesia, Nazi Germany.
But our story is different.
It is based on the paleontological evidence that shows mass destruction of species in our Mother Earth is a cyclic process, repeating in a specific time interval. In the last 500 million years of history of the earth, there was at least five such major mass extinctions were identified. They are 450 Million years ago, 360 million years ago, 250 million years ago, 200 million years ago and 65 million years ago, the latest in which whole set of the dinosaurs species were believed to be destroyed. (Read the ‘Great Dying’).

BUT Man is such a kind of marvelous animal who can travel back and forth through time. He can make a well defined destruction plan as well as a survival plan. Such a survival plan had already made, a plan for the next 10^18 years, or even beyond

University of California, Santa Cruz astronomer and Science’s leading ‘soothsayer’ Greg Laughlin is the man behind such a plan. He started making the generous assumption that humans can survive multiple ice ages and deflect an inevitable asteroid or comet strike. NASA predicts that within a period of 1 billion years, there is at least 10 chances of hitting the size of the rock that wiped out the dinosaurs.

But one major problem is that within in a billion years, our Sun will start aging and will start emitting 10% more energy. The oceans will boil away and the atmosphere will dry. The temperatures will soar past 700 degrees F.
 
 
 


Then the Red Planet, Mars, will be a safety spot. There is enough water stored in the ice caps to submerge the planet with a 40 feet deep ocean.  After 4.5 billion years, when the whole hydrogen fuel is converted to Helium, our sun will become a red giant, (A red giant is a dying star in the last stage of the stellar evolution) 250 times as large and 2,700 times as bright as it is now, stretching the vast space of the solar system and engulfing Mercury, Venus, and Earth and turn Mars into a molten wasteland. Then we can inhabit to Saturn’s Moon, Titan.
 
Finally, about 130 million years after the red giant phase, the sun will go through a final spasm and eject its outer layers into space, leaving behind a white dwarf.
 
 
White dwarfs are the most stable stage of star having 0.7 to 1.4 solar mass. This 1.4 is known as Chandrasekhar limit. This will be an extremely dense star having densities reaching up to 1,000,000 times that of water. A star that ends its nuclear-burning lifetime with a mass greater than the Chandraskehar limit must become either a neutron star or a black hole.
 
 
Then the option is to successfully colonize planets orbiting Proxima Centauri, about 4.2 light years from Earth or another red dwarf. We can enjoy trillions of years of calamity-free living. When proxima Centauri perishes, humanity can relocate to another red dwarf and then another.

Proxima Centauri is a red dwarf about 4.24 light-years from Earth, inside the G-cloud, in the constellation of Centaurus. It is the nearest star from our Solar System, and is a prime candidate for future interstellar travel and space colonization mission. Current rockets are too slow that they would take 100,000 years just to reach the there.



The serious problem starts, if the universe is going for a big crunch after about 10^18 years. The only option is to escape this universe before it chills, rips, crunches, bounces, or snaps into nothingness. As per the String theory, there are other universes hidden from our view—as many as 10500. At least one should be suitable for life.
