Through the 4D Magellan strait to reach the promised land a century later

Rating: 10/10 (18 November 2014)

1st November 1520 Ferdinand Magellan crossed the border of the Earth through what will be named the strait of Magellan. This day the reality of the earth being a 3D sphere was touched with men's blood and sweat.
This is a sort of recursive path : Magellan crossed the horizon of earth through the Magellan strait.
In the same way, Nolan bring us to cross the 4D horizon of this universe through the strait of a gravitational hole in 4D space. This is also a mad recursive way of salvation. The travel is fantastic for the eyes and for the brain.
Before this day I clearly understood the relativist twin paradox (which isn't a paradox at all). Interstellar is my first time... I had such a deep feeling to witness what the twin paradox means in real life. One scene stayed within my brain for many days:
Cooper seeing Murph for the last time, after so long,
and having to go ahead with this same vision...
Nolan pay with Interstellar a large tribute to Kubrick and Zemeckis, and at the same time exceed their visions. He inseminate our brain with a few new problems :
 We have to look in the eyes the end of humanity on earth.
The pressure is increasing
we see and feel the climate roaring at us,
we will have to all convert to work in the agricultural field
and we will have to rewrite history to make our children love this fate.
 Facing such an hard fate, which « love » will lead us to hear a non existing message and walk to cross the horizon of the universe ?
Is it the love of:
- ourself,
- our beloved,
- our children,
- the condemned part of humanity (we will probably not be able to move 20 billions human being, with a magic plan A),
- the future humans (plan B) ?
 A lot of path toward the unknown are fundamentally recursive.
This may look like a fundamental problem:
how to pass through a strait which will be conceived (understood) in the future. Look at what Magellan did.
This is simple trust to enter this recursive loop.
To make this trust spring, we need physicists but also great writers and artists which will make us see and cross the horizon.
Nolan is one of these magicians.
