The fourth dimension

If I had to choose a superhero to be, I would pick Superman. He's everything that I'm not.

If you've watched this. DONT READ!

We say, a car travelling along a straight line is a one-dimensional motion. The same car, when travelling along a curvy road, is a two-dimensional motion. Along the hilly ups and downs, turns and bends, the car travels in the all three dimensions of physics. But I would say, the car were travelling in two, three and four dimensions respectively, the added dimension being the TIME.

Space, being the first three dimensions has a negative axis, but time is a dimension where the negative axis can violate humans fundamentals of physics.

There is reason for everything, might be violated because, as we can travel through negative time, we can kill our self in our past which can result in a absurd state where we don't have the answer for "who kill me?".

To travel through time, we have three options, a wormhole, a black hole or else just travel faster than the cosmic speed limit. 

The cosmic speed limit, being the speed of light is considered to be the ultimate speed. Above that speed everything seem to be in slow motion so that the fundamentals are not being violated. Another reason for the ultimate speed is maybe because we don't just see the reality. We are just seeing the past. 

Consider a train faster than light travelling towards us. Imagine that we can see it approaching us, then before it reaches us, we will get get hit by it, because we only see the train's past. The reality is faster than light that, reality becomes the future. 

All these crazy theories are so true that time travelling may happen in the near future.
