We all know the speed of light, and also the fact that nothing can travel faster than light.

Before we try to find anything that can travel faster than light, we need to understand or answer the question,should there be a speed limit ?

Even if we are able to find something that can travel faster than light, we would be hit by a fact, that there is a speed limit in our universe, because of its nature.

Lets assume that qt is the smallest quantum of time, and qs is the smallest quantum of space. To travel 3 blocks or (n) blocks of qs, we would need 3 or (n) units of time. That is to travel n*qs, we would need n*qt, and hence the maximum speed that can be achieved is qs/qt.

The hypothesis here is, for something to travel from qs1to qs3,the minimum time required is 3*qt, rather any energy or matter can only travel one qs per one qt of time. We are assuming that qs1,qs2,qs3 arein a straight line.

Now, why is the speed of light constant, independent of the speed of the viewer. Thats for later :)

Addendum1:

It would take 4*qt time for the fastest energy to travel from qs1 to qs2, otherwise there will be two actions taking place in one quantum of time, the actions being

1. the quantum energy being in qs1
2. the quantum energy moving from qs1

Similarly

1. the quantum energy moving into qs1
2. the quantum energy being in qs1

Energy means - quantum energy or quantum particle
