博客來Time is something we grow up thinking we understand: a steady rhythm marked by clocks, days, and the rising of the Sun. However, modern physics tells us a very different story. Since Einstein, time has been revealed as flexible, intertwined with space, and shaped by the speed of light itself and through the eyes of famous telescopes like Hubble and the James Webb, we now are given the opportunity to see light that has travelled billions of years, carrying captivating images from the early universe. Yet, because our everyday lives unfold on human scales, we rarely feel the true variability of time because of an underlying factor that hinder our appreciation in full of Einstein’s relativity: this factor is experience.
The truth is that light is absurdly slow from a cosmic perspective, but senselessly fast in our perspective. The author brings readers of all ages to value and understand the true nature of time, with a fascinating journey through cosmic scales: from Earth to black holes, where we will feel time as an unparalleled new dimension. Something that can bring us to the future, and maybe even to the past.
