It is illogical to believe that there is no difference in temperature. Temperature is a measure of the energy derived from the motion/vibration of subatomic particles, hence there would still be a temperature if no subatomic particles were moving at all - the temperature would be absolute zero. Would you be able to sense hot, cold, or regular temperatures? Why not? Because the temperature isn't right. To be honest, it's difficult to fathom a situation like this because you'd die almost instantaneously at absolute zero. However, if you try to envision a universe in which life is possible, motion is conceivable, energy is conceivable, but there is no such thing as temperature, you are imagining a world so unlike our own that there is no way of knowing what it would "feel like."
