Who doesn’t remember the years of their childhood as being much longer compared with those lived though after adolescence? Why does it seem to us that time slows down when we experience a dangerous situation? Films appear to be shorter the second time we see them, just like a journey from one place to another is shorter when it’s not the first time we do it. At least from the subjective point of view, time is not rigid. It is a highly malleable cerebral construction.
To understand better the phenomenon of the subjective perception of time, Eduard Punset has interviewed a young man of many talents and scientist with a promising future. Neuroscientist David Eagleman is Director of the Laboratory for Perception and Action at the University of Texas Medical School in Houston.
What do neuroscientists do to understand how the brain reconstructs events in time? Punset listens first hand to the explanations of Eagleman, who will soon return to Redes to talk about synthesis, another of his fields of research.

Time is presence of motion and forces and is due to expansion of space. Time is slow where expansion of space is slow as in gravity. As total motion(time) imparted by expanding space to a mass is a constant therefore when an objects velocity is increased the motion within the object slows this is perceived as slower time.
