Interstellar the Movie

I saw "Interstellar" on Putlocker a couple of days ago. Although the slow internet and the quality of the video was stressful for me (made me want to throw the keyboards out the door), the story did manage to hook me despite of everything.

    1. In Earth's future, a global crop blight and second Dust Bowl are 
    2. slowly rendering the planet uninhabitable. Professor Brand
    3. (Michael Caine), a brilliant NASA physicist, is working on plans
    4. to save mankind by transporting Earth's population to a 
    5. new home via a wormhole. But first, Brand must send former 
    6. NASA pilot Cooper (Matthew McConaughey) and a team of 
    7. researchers through the wormhole and across the galaxy to find
    8.  out which of three planets could be mankind's new home.
The movie is slow and more of thinking movie than a techno-action sci-fi.

1. Time Dilation 

There are many movies that featured Einstein theory of relativity, but this film did great in showing the effects of time dilation. When Cooper, Doyle, Amelia and robots TARS and CASE landed on Miller's planet, a water planet, to investigate if it could support life, they were caught off guard by giant waves that killed Doyle and marooned the shuttle for an hour or so and when they returned to their ship Endurance 23 years had already passed..

The time dilation was due to the strong gravitational pull of the black hole Gargantua. The stronger the gravitational pull, the slower time ticks. And according to Einstein's theory, inertial and gravitational mass are the same. That's why when an astronaut is in a speeding vehicle like say a rocket nearing light speed, his time slows down compared to the people on earth. Speed increases mass, and mass is relative to gravity: the larger the mass the greater the gravity. black holes have massive mass and gravity that light could not escape from it. That's why they are called black holes, by the way. Hmmm...obvious enough.
Bending time and space.

2. Wormholes.

Distance is the main problem with interstellar travel. Even if a ship that could travel as fast as light, it would still take years to visit the nearest star and hundreds and even millions of years to explore our galaxy.

So, instead of inventing an engine that could move a vehicle or a spaceship from point A to point B at great speed, scientists have this idea of bending time and space. It's like driving a car from Taytay to Cebu but instead of the vehicle moving, the whole of the Philippines was bent allowing the car to get to Cebu without leaving its position, its the roads under the car that moved! Of course,this will take massive amount of energy and according to a physicist about the power of a star.

In the movie, a wormhole appeared near Saturn (or Jupiter) and NASA sent probes and later astronauts to search for habitable planets for the emigration of the survivors or the genes of the survivors on Earth.

3. Fifth Dimension

We live in a three dimensional world. 

3 Dimensions: L,W and H.
spatial dmension
2 deimensions: L and W
Easy to understand think of movies. 2 D movies have length and width or lines: plane. One Dimension is line and the other is plane. Now with 3D movies, depth is added: space. The third dimension is space. these are spatial dimensions. This is how we are able to coordinate location .

4 Dimensions 3 spatial dimensions+Temporal

Fourth dimension is time. In three dimension we could place location but with the addition of time as fourth dimension, it is now possible to locate "events". Think 3D movie again, but since we are outside the 3d movie, we could go to and fro through time in the movie.

In the movie, Cooper  sacrificed himself so that Endurance and Amelia could survive. He was sucked into the black hole and later found himself floating behind his daughter's multi-level bookcase. with each level, he could see events in the past. He was later able to manipulate objects to send messages to her daughter in the past. In the  present, Murphy, Copper's daughter, realized that it was her father who has been talking to him in codes from the past. She discovered that the data on gravity was being transmitted by her father in morse code through his watch which was given to her before Cooper left for space.

The tesseract (3 dimensional representation of time-space) collapsed and Cooper was sucked into the future rescued by a NASA space station travelling towards Edmund's planet. Cooper was reunited with his daughter Murphy who was 120 years old then.

There will come a time when humanity will
surpassed the limitations of biological bodies
brain and move on to the next level: the Singularity
What's the fifth dimension then? Cooper was outside space and time. Sapce-Time was represented in 3 dimensions where Cooper was able to move about inside looking out at temporal locations. This is the fifth dimension.

4. They.

Humanity was saved by entities called they.  They created the wormhole that enabled NASA to travel interstellar and they, according to Cooper, also allowed him to go into the fifth dimension. Who are they? They are us from the future.
