Assume a train travelling in the speed of light and I was running inside the train along the train , is it am travelling faster than light ?
If I am on a train -LRB- hypothetically -RRB- moving at the speed of light -LRB- c -RRB- and I start running at a speed of 5 km/hr in the same direction as the train , am I now moving at a speed of c + 5 km/hr ?
