How can you detect a time two times faster, i.e. if all entities in the universe, you included, moved and grew old suddenly two times faster, without any knowledge in science and without sophisticated measuring apparatus?

If every thing suddenly goes 2x faster, then I do not think you'd be able to notice it easily. The easiest, and at the moment, only way I could think of would be to use some sort of doppler shift phenomenon. Assuming the speed of sound or light remains a constant, then a passing racecar would have a higher pitch than it did before as it approached you.
