I've recently become somewhat obsessed with Space and Time. I've lost count of the number of documentaries I've seen since mid Feb.

The concept of time has been making me think a lot recently. This idea of space time and time dimensions has got my mind spinning. Surely time is nothing more than a concept. We humans came up with to introduce some sort of order to the world. Nothing more and nothing less.

And that talk of time travel (into the past or future) is nothing but Sci-Fi fantasy.

Of course such a journey would be a one way event, you would be leaving everyone and everything you knew behind. The physics in the movie Interstellar (ignoring the last 15 minutes :p) are sound, Miller's planet they went to where 1 hour there equates to 7 years back in Earth time is a real concept.

Time travel into the past is a big can of worms though. Some believe it will never be possible (and I am on that boat also), whereas others believe it would only be possible from the point a time machine was built and turned on. Neil deGrasse Tyson talks briefly about this in a Cosmos episode if I remember right. I don't think going backwards in time will ever be possible due to the humungous paradoxes that come into play by doing so. The major one is likely time-loops. You'd effectively be creating a loop every time you went back in time, because there would be a point where time reaches the point of going back in that timeline's future.

Great movie. Enjoyed every second!

However that whole series of events simply baffled me. The fact everyone, apart from Matthew didn't age doesn't compute. This whole bending and warping of time... Its surreal!
