Rethinking Reality: Space, Time and Gravity
Δημοσιεύτηκε στις 16 Φεβ 2017
With
Sam Gralla. At the dawn of the twentieth century, Einstein
revolutionized our conception of reality, showing that space and time
are not merely the stage on which the show unfolds, but dynamical
entities that stretch, bend, and vibrate to give rise to the force we
know as gravity. A century later, the vibrations of spacetime have been
directly detected as gravitational radiation from colliding black holes,
confirming Einstein’s prediction and ushering in a new era in
observational astronomy. How did physicists measure these minuscule
vibrations, and what does it mean for our understanding of the universe?
And what is the next revolution, fomenting right now, in our conception
of space and time?
