The reason why we go to space

The space exploration has intangible value.
It's stimulus for people.
Kids always go crazy about the space,
specially if there are some astronauts in front of them.
Even it's good for the economy.
Also through out our history the human kind always keep exploring the new world which used to be considered as a mystery. From Australopithecus to Columbus, Maseran and Wright brothers.
People always try go further in nature.

Interstellar

I watched the film "Interstellar" today.
It was good, especially about the time and space, relativity thing.
The scene that dad is in his daughter's time-space room.
The five dimensional room is good image to me.
It makes me re-think about time, space and our future.
