Oh so, whenever we go at the speed of light (im sure you do that every day) we have to know what is the maximum speed that we can go with respects to the eye of the beholder (remember Theory of Relativity?) We also need to know what will happen in about 2 eons from now and whether the total useful energy of the Universe is greater than or if its equal to 0 (thermodynamics?). We also need to know if we can perform telekinesis (According to M-theory (which is one of those superstring theories) we can)
